Arduino Wiring - SimonTelescopium/PowerBuddy-Arduino-Sketch GitHub Wiki

I've tried to keep the sketch as flexible as possible in order to ensure that you can wire the Arduino UNO to suit your set-up.

below is a diagram showing how I set mine up.

IMPORTANT NOTES:

  1. Read the Instructions in the sketch before you connect the capacitor - this has to be connected after you have finished commissioning the software or you will not be able to upload your sketch.
  2. I use locking connectors for power, these have a number embossed on next to each pin - THERE IS NO STANDARD FOR THESE some mount manufacturers are now using these so beware their pin out may not be the same as what I used it is your responsibility to get this right - not mine! - check and double check before connecting any equipment that your polarities are correct.
  3. The software assumes your relay board turns on to a positive signal on the data pins.

Suggestion for how you might wire your Arduino Uno
