robodatech.Switch pumps, lamps, valves, and classroom loads through relay modules.
Open in compiler →Source code and build tools are available in the protected platform workspace.
How it works
Practice this Arduino feature with a verified Roboda sketch.
- Read the constants at the top of the sketch.
- Wire the pins exactly as listed in the pin map.
- Upload or compile once before changing values.
- Change one value at a time and watch Serial Monitor or the output device.
Connections
| Pin | Connect to | Note |
|---|---|---|
| D10 | Relay module IN pin | Use a relay module/driver, not a bare relay coil from the Arduino pin. |
