In this TV, we will be creating an electronic keyboard.
In this TV, we will be creating an electronic keyboard. Each key plays a different note, and it cam be configured by programming.

Note that this part can be tricky to solder straight. The easiest way is to get 1 pin soldered, even if its' crocked.

After this, the header should be lined up.

Next, se need to solder the USB Serial adapter onto the header pins. This board converts the serial protocol that the processor speaks to usb.
This converter chip is a fine pitch surface mount part, so we have it on a premade board. With practice, it is possible to solder parts this small though!
Just like soldering the header, solder 1 pin in place, align the module, and then solder the rest of the pins.
Make sure the board isn't at an angle, because we need to leave room for the USB cable to plug in.

Next, we need to attach the speaker.
Go to the wire cart, and grab 2 lengths of stranded wire, each about 4 inches long. Strip the ends of both using the stripping tool at the soldering station, and then twist the wires together.
Solder 1 end of the wires to the speaker, and the other ends to the board. It doesn't matter which connection goes to which pad, it works either direction.

The last thing to solder is a bypass jumper where the large capacitor was. An easy way to do this is to use one of the cut off leads from the resistors.
Fold it into a U shape, feed the wires through the holes, and solder it in place.

Now just add the keycaps, and were done with the hardware!

==Software==
For the code, we will be using the Arduino IDE. It's on the lab computers, or it's free to download.
In the main window, copy this code:
[[Media:Tone_arduino2.ino]]
under tools > board, select Arduino uno. Then, connect a usb cable from the board to the computer. under tools, make sure that the "com port" is set to the listing in the drop down; this is the device on the other end of the usb cable. Then, select upload!
