1 The LadyUno Sound Unit

2 Here s what we ll need for this project

3 We start with our finished Lady Ada Wav Shield.

4 5V for LCD Serial Data for LCD GND for LCD 5V (coming from the BBB) is_lady_ada_busy PIN GND rx PIN Install female headers on the Lady Ada Wav Shield (details follow)

5 Cut your female headers with your wire cutters.

6 Install 2 Pin female headers on holes 6&7, 7&8

7 If you need to trim the header more tightly, you can send them smooth with sandpaper or a nail file.

8 Install 2 Pin female headers on holes 0&1

9 Maybe yours will be more straight than mine!

10 Install female headers on holes GND through Analog Pin 5

11 Make sure that you solder in the cluster of 6 male header Pins on the Lady Ada board.

12 We ve now completed the Lady Ada Wav Shield & Arduino Uno sandwich!

13 Now we will get the LCD display set up.

14 With your LONG male header Pins... cut off a group of 3 Pins.

15 Step 1 Step 2 Step 3 Using your small pliers, bend a long leg of the LONG male header in the above order.

16 It should look like Insert the altered male header into the LCD s connection cord. this when you are done. The other side of the altered pin should connect to the WHITE wire.

17 Black wire to Gnd Red wire to PIN Vin White wire (serial data out to LCD) -- connects to PIN A0 The cord/header will now be inserted into the Lady Ada board.

18 I like to mark the positive Pin (+5V) with silver marker. This helps me to not hook things up backwards.

19 Connect the BBB to a breadboard.

20 We have now completed our LadyUno Sound Unit!

21 Now we have to connect our LadyUno Sound Unit to the BBB/breadboard in order to use it properly.

22 You ll need the 2 servo cables that you were given in class this week.

23 On one of the cables, cut through the center of the connector (sacrificing the Red wire).

24 Separate and trim. Cut the red wire so that it is out of the way.

25 Cut 6 - single LONG male headers to use to connect the cables to the boards.

26 Insert the single LONG headers into the connectors.

27 You ll cut 3 of the 4 ends this way. Leave one end intact.

28 On the intact connector - mark the White wire with silver marker because we are going to use it as our +5V line.

29 We will use the ICSP header to provide +5V and Gnd to the LadyUno Sound Unit.

30 Gnd +5V Connect the intact 3 wire connector. It will provide power and ground to the LadyUNO from the BBB/ breadboard.

31 On the other end of that same cable, mark the White wire with silver - denoting its +5V usage.

32 Now our LadyUno is connected to +5V and Gnd.

33 The final step is to connect the serial data connection and the Lady Uno is busy connection.

34 One end of the cable will attach to the LadyUno.

35 Make sure that you solder in the cluster of 6 male header Pins on the Lady Ada board.

36 The White wire will connect to PIN 0 - (NOT A0). The is the Receive or RxPIN.

37 The Black wire will connect to PIN 6. When the LadyUno is playing a file it will be HIGH. When the LadyUno is not busy playing a file it will be LOW.

38 The White wire is connected to BBB Pin 11 - for serial data send from the BBB to the LadyUno. You can change this in the controller sketch.

39 The LadyUno is busy playing a file wire will be connected to Pin 10. You can change this Pin assignment too - in the controller sketch. You do not need to use this capability (or wire). It is optional.

40 I added an LED to the busy wire. When the LadyUno is busy then it will light up - providing some visual evidence.

41 Here is our complete LadyUno Sound Unit.

42 I can tape up the connector wires to make a nice simple connection.

43 I think that we can now view the system from this point of view - as the LadyUno is now a system separated from the BBB -

44 Now our BBB can control the LadyUno with 1 (or 2) Pins - And our BBB is free to do more things to make our projects work.
