x ARCHIVE: Hardware_Electronics Box (v1)

The original electronics box (version 1) was designed around the Arduino Micro. The box could be triggered by audio input or photodiode input and had a 5V output for powering/triggering a pump. Three LEDs indicated various events.

Construction

1. Solder wires onto panel mounted switch and audio jack. Attach 2 resistor's in parallel to the end of the wire attached to one of the switches end pins.
   

2. Attach the two panel mount components' black wires.

3. Solder together the three LEDs with a common ground and a resistor in series with the green LED . Notes: The input of the LED (colored wires) is the side with the longer pin, the ground is the side with a flattened edge on the bulb itself.
   

4. Solder the arduino micro, surface-mount audio ports, diodes, and transistor to the PCB Notes: You may need to cut the PCB down to size beforehand. Make sure the diodes and transistor are facing the correct directions, the PCB is marked with a notch for the transistor and a filled in side for the diodes to make this easier.

5. Solder the LEDs to the board.
   

6. Solder the panel mount components to the board.
