5 Then We Got Sidetracked After taking a year away from the Arduino to write ARRL s new book, High Speed Multimedia for Amateur Radio, ARRL now has me working on a sequel to my first book, Arduino For Ham Radio. With any luck, the book will be out in time for Dayton/Xenia In the time since the first Arduino book, the Arduino world has changed dramatically, with an emphasis on newer, faster processors and the addition of built-in wireless networking on many of these new boards But wait, there s more

6 Then We Got Sidetracked Again

7 How Big???

8 Now Back to The Arduino The Arduino and the now many variants is a group of very versatile, inexpensive, and easy to use microcontrollers Because of this, they have rapidly become the development tools of choice for Makers and Hams alike The Arduino s versatility allows it to be used for simple children s projects, complex robotic and other Maker projects, and a wide range of Ham Radio applications Many 3-D Printers are actually powered by an Arduino The Ten-Tec Rebel and Patriot are powered by an Arduino variant The Arduino now has direct transceiver capability with the development of the HobbyPCB RS-UV3 and HamShield add-on shields along with other devices

9 The Arduino is for Kids The Arduino can be used for youth projects such as the Firefly Jar and other easy-to-build projects In conjunction with the Horn Lake Library, a group of hams from the Olive Branch Amateur Radio Club led a 3 day Practical Robotics seminar, where the kids built and programmed their own Arduino-powered robotic carts An Arduino-controlled animatronic diorama was the hit of the Library s summer floor display. Even now, the kids aren t sure if there were real critters in the display case

11 Kids and Arduino Robotics

12 Animatronic Display Powered by 3 Arduinos Used motion sensors, relays, motors, solenoids, and Taxidermist LED-lit eyes to simulate the critters

13 The Arduino Is For Makers The Maker community uses the Arduino to create all kinds of projects, including flying drones complete with autopilot, robots, and even automated paintball guns The rapidly expanding new area of wearable electronics (also known as e- textiles) is powered by the Arduino

38 Cool Things About Arduino Modules The sensors and devices used on the Arduino are easy to interface. Most have program libraries already written to do all the work for you. Many communicate using I 2 C/TWI (Inter- Integrated Circuit Two Wire Interface) or SPI (Serial Peripheral Interface) serial communication I 2 C/TWI is a two wire bus-oriented communication protocol that requires only two wires. Each peripheral device is accessed via its pre-programmed hardware address SPI is a bus-oriented protocol, allowing many sensors to communicate with the Arduino over a single shared bus. Devices are selected via hardware selection lines

39 What Can You Do With An Arduino? The better question to ask is what can t you do? With the Arduino, you re only limited by your imagination The Arduino is ideally suited for applications where you want to sense and control things Programming the Arduino is easy. Through the use of the Arduino Integrated Development Environment (IDE) and libraries (modules other people have already written), the actual programming often takes less time than it does to hook up your sensors and controls. The Arduino IDE now supports many of the newer ESP8266, ARM Cortex, and other variants Some of the Arduino projects I have built: Portable CW Keyboard with Programmable Memories Portable Satellite Tracker Rotor Azimuth/Elevation Controller Lightning Detector And much more as you will see in a bit

Programming The Arduino Programming the Arduino is done using the Integrated Development Environment (IDE) The Arduino programming language is based on C and C++, but is largely modeled on the

40 Programming The Arduino Programming the Arduino is done using the Integrated Development Environment (IDE) The Arduino programming language is based on C and C++, but is largely modeled on the Processing ( language Arduino programs are called Sketches Allows the seamless integration of previously-written code libraries (usually written by someone else) The programming language is very easy to learn and with just a little bit of study, you can be producing usable code very quickly

41 Libraries Are Your Friends One of the really cool things about the Arduino is the way you can integrate pre-written code libraries into your sketches A number of common libraries are automatically available from within the IDE. Any additional libraries you download are also accessible from within the IDE Libraries are one of the neatest things about the Arduino and Open Source. Everybody is sharing the libraries and hardware they create. The hardware and software for the Arduino is all Open Source And the best part A lot of this cool stuff is free. The IDE is free, the libraries are free. Even the PC board designs to build your own Arduino are free. The pre-built boards, shields, sensors are all low cost. It doesn t take a huge investment at all to get started with the Arduino

42 Libraries - The Dark Side Once you go beyond the standard libraries included in the Arduino IDE, there is an amazing number of libraries other people have created. This is both a wonderfully good thing and cause for potential headache By nature of the beast, Open Source software is created by people like you and me. In a few cases, the libraries you download don t do what you think they should, or have errors In the case of the Morse Code Library, it was not 100% accurate and would occasionally send the wrong character In the case of the PS/2 Keyboard Library, it didn t allow the use of the F- Keys Fortunately, libraries are written in C and easily modified. I m not a C programmer, but I was able to figure out how to modify these libraries to suit my needs in just a few days

43 The Arduino and Amateur Radio Amateur Radio and the Arduino go great together Since many Hams love to tinker and build things, the Arduino is that perfect tool for those quick projects we re always thinking up For example, I built a Morse Code (CW) keyboard as my first Arduino project. The actual project took longer to interface the keyboard and other components than it did the actual coding From start to finish, the project took about 2 weeks to get working and another week or two to add features and package it into a usable prototype Remember, this was my very first Arduino project

The CW Keyboard Uses an Arduino Uno and a PS/2-style Keyboard Sends the CW equivalent of what is typed on the keyboard and also displays it on the LCD display Added features include: Adjustable

44 The CW Keyboard Uses an Arduino Uno and a PS/2-style Keyboard Sends the CW equivalent of what is typed on the keyboard and also displays it on the LCD display Added features include: Adjustable sending speed LCD backlight on and off Audible beep for code practice or a relay output to actually key a rig 5 user programmable memories with 40 characters each Uses standard PS/2 keyboard Runs off a 9-volt battery Total cost: about $30

45 Into The Unknown With an Arduino and a handful of inexpensive parts, we can build our own feature-rich Arduino-powered Transceiver

Arduino Transceivers Combining the Arduino with a low-cost 40m QRP CW transceiver board, a DDS, a Nokia display, and a rotary encoder should give us everything we need It could cover the entire 40

46 Arduino Transceivers Combining the Arduino with a low-cost 40m QRP CW transceiver board, a DDS, a Nokia display, and a rotary encoder should give us everything we need It could cover the entire 40 meter band How about adding dual-speed tuning? Why not give it dual-range RIT too? Theoretical Transceiver Block Diagram While we re dreaming, why not throw in a built-in Keyer (Iambic A, Iambic B, or Straight Keying) with adjustable speed?

40m CW Transceiver Board Available on ebay - $12 kit or $22 preassembled Based on the NoCal Forty-9er 1.8W Output Rockbound on 7.

47 40m CW Transceiver Board Available on ebay - $12 kit or $22 preassembled Based on the NoCal Forty-9er 1.8W Output Rockbound on MHz Direct Conversion NE602-based Receiver Easily built in a single afternoon The instructions alone are worth the price of admission Frog Sounds V3 40m QRP CW Transceiver Kit

48 Lost In Translation Read the instructions carefully, then put them aside, you won t need them. Here s why: This is the maximum power of frogs, at the same time suite power output using the American ring, so that the "Jungle" with the remote communication ability, enhance the "practical frogs"! The headset with the beat hair drops pattered generated audio Avoid prolonged shorting key launch, or D882 and dummy load fever large, carefully damaged Carefully adjusted, you will receive an unexpected effect. In the dissemination of good times with a signal on a distant contrast reception, this local effect is no difference between basic commodity machine, which makes unexpected Communication distance of about km more secure, to greater distance depends on the propagation environment and the operator's operating skills

49 Add An Arduino and A DDS And you now have a fully functional 40m QRP CW transceiver with a built-in 5-35 wpm Iambic keyer, and dual range tuning and RIT

But Wait - There s More Let s do what we did with the Ten-Tec Rebel and add JT65 to it By digitally shifting the DDS output frequency, we can precisely shift the carrier frequency, as we would with

50 But Wait - There s More Let s do what we did with the Ten-Tec Rebel and add JT65 to it By digitally shifting the DDS output frequency, we can precisely shift the carrier frequency, as we would with standard FSK. This carrier offset will cause the receiver to hear the frequency shifts just as if they were normal analog audio signals Instead of sending audio, the PC program sends command codes to select the desired carrier offset frequency This method could also be used to digitally generate RTTY, PSK31, and other digital mode transmissions

51 The World s First (?) Homebuilt Digital JT65 Transceiver Cost To Build: $65 Won Best in Show in QRP- ARCI Four Days in May homebrew contest at Dayton 2015

52 So We ll Say It Again When it comes to the Arduino, you are only limited by your imagination As long as it doesn t violate the laws of physics If it does violate the laws of physics, just use a bigger hammer
