For this project I used a raspberry pi 3b. However, any pi should work the same. I used a Sainsmart 8 channel relay, with the intention that at some point i could easily expand the number of valves simply by creating another instance of the PiPonics object inside of piponics.py.Connect the relay to the gpio headers using physical pin numbering as follows;
| Growbed | Power | Valve One | Valve Two | Pump | Ground |
|---|---|---|---|---|---|
| Relay | VCC | in1 | in2 | in3 | GND |
| GPIO | 5v | 36 | 38 | 40 | GND |
