1 Electronic Organ PART NO This project is based on IC555 timer circuit that is capable of providing the set of musical notes: DO, RE, MI,... And with the help of some components and essential devices, the project can be made. The circuit is basically an oscillator constituted with an integrated circuit 555 and some different values of resistor to generate a signal output with different frequencies. In a nutshell, if you assemble this project, you will obtain a circuit generates musical notes. Time Required: 3 hours depending on experience Experience Level: Intermediate Required tools and parts: Soldering iron and solder 6ft of wire (#22) Wire cutters Needle nose pliers Bill of Materials: Qty Jameco SKU Component Name BREADBOARD 3.25X PNT This component is basic to develop the project Switch Tactile ON OFF Single Pole, Single Throw Round Button PC Pins 0.05A 12 Volt Thru-Hole This component is fundamental to achieve the project PACK OF 5% 1/4 WATT CARBON FILM RESISTORS, 6.8K OHM This component is vital part of the project PACK OF 5% 1/4 WATT CARBON FILM RESISTORS, 4.7K OHM This component is essential to the project PACK OF 5% 1/4 WATT CARBON FILM RESISTORS, 3.3K OHM This component is a necessary part to the project PACK OF 5% 1/4 WATT CARBON FILM RESISTORS, 2.2K OHM This component is important part of the project PACK OF 5% 1/4 WATT CARBON FILM RESISTORS, 5.6K OHM This component is necessary to develop the project RESISTOR,CARBON FILM,8.2K OHM,1/4 WATT,5%,(100 BAG) This component is indispensable to the pproject RESISTOR,CARBON FILM,10K OHM,1/4 WATT,5%,(BAG OF 10) This component is obligatory in the project Standard Timer Single 8-Pin MDIP Rail This device is the core of the project CAPACITOR,RADIAL,22uF,50V,! 20%,85C,5x11x2mm,(10) This component is basic to achieve the project uF 100 VOLT MYLAR CAPACITOR This component is fundamental to develop the project uF 50 VOLT MONOLITHIC CAPACITOR This component is unavoidable in the project INCH ROUND FERRITE PAPER SPEAKER

2 Step 1 - Materials for your Electronic Organ In this step, you will identify the following parts: 2 Breadboard 3.25" X 2.125" 400 Point 9 Switch Tactile OFF-ON Single Pole 2 Resistors of 6.8K, 1/4W 2 Resistors of 4.7K, 1/4W 2 Resistors of 3.3K, 1/4W 2 Resistors of 2.2K, 1/4W 1 Resistor of 5.6K, 1/4W 1 Resistor of 8.2K, 1/4W 1 Resistor of 10K, 1/4W 1 IC555 Timer 1 Electrolytic Capacitor of 22 F, 50V 1 Capacitor of 0.01 F, 100V 1 Capacitor of 0.1 F, 50V 1 Speaker of 8, 0.25W Step 2 - Identify the Tactile Switch s You will need to identify the pins of each tactile switch of your project.

3 Step 4 - Connect the Pin D to Terminal Positive Connecting to terminal positive of your protoboard each pin D of each tactile switch. Step 5 - Identify the Pin A of the Tactile Switches Identify the pin D of each tactile switch.

4 Step 6 - Connect the Resistors All resistors should be connected to each pin A of each tactile switch. Step 7 - Identify the Pins of the IC555 Timer Mount your IC555 on the other breadboard. Step 8 - Connect the Resistor of 10K The resistor of 10k should be connected to pins 6 and 7 of the IC555 timer.

5 Step 9 - Connect Pins 2 and 6 of the IC555 The pins 2 and 6 of the IC555 timer should be interconnected. Step 10 - Install the Capacitor of 0.1 uf Between terminal negative and pin 2 of the integrated circuit should be connected the capacitor of 0.1 uf. Step 11 - Connect the Capacitor of 0.01 uf Between the pin 5 of the IC555 timer and terminal negative of the circuit, you should connect the capacitor of 0.01 uf.

6 Step 12 - Connect the Resistor of 6.8K Connect the resistor of 6.8K to pin7 of the IC555 timer and the other end will wait to be connected to the resistor of 4.7K of the other breadboard with the tactile switches. And the pin 1 of IC555 timer should be connected to terminal negative of the circuit. Step 13 - Connect Pins 4 and 8 of the IC555 Connect Pins 4 and 8 of the IC555 to terminal positive.

7 Step 14 - Interconnect each one of the Polarities Interconnect each polarity correctly, i.e., connect the terminal positive with the terminal positive. Then, connect the terminal negative with the terminal negative. Step 15 - Connect the Electrolytic Capacitor of 22 uf Connect the Electrolytic Capacitor of 22 uf between the pin 3 of the IC555 timer and the speaker. You should connect the pin 3 with the terminal positive of the capacitor, and the terminal negative of this with the terminal speaker later.

8 Step 16 - Connect the Speaker Connect the speaker between the terminal negative of the circuit and the terminal negative of the electrolytic capacitor of 22 uf. Step 17 - Complete your Project Complete your project by joining both breadboards that with the tactile switch and the other with the Integrated circuit. Then, you need to connect the terminal positives of both breadboards and the end isn't connect of the resistor of 6.8K to the resistor of 4.7K.
