3add BNC jacks and wire everything up!
On the MCP4725, connect GND to ground, VDD to 5V, SCL to A5 on the shield, and SDA to A4 on the shield, like this:

If you want to make SignalBuddy truly happy, you can add the following bells / whistles:
- Tap the 4 holes in the base for M2.5 screws to screw-mount the Arduino.
- Tap the 4 holes in the inner brackets of the lid so the box can be securely closed with M2.5 screws.
- Add a button to the cutout near the USB jack. Wire it such that pressing it causes the trigger pin to go high, making SignalBuddy deliver signals with the push of a button.
- Add LEDs to the holes beneath the BNC jacks. Splitting the PWM output of analog output to a pair of LEDs will cause them to light up as signals are delivered to external devices.
Download the code and follow the instructions on the SignalBuddy github repo to generate your signals!
