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 |
|---|---|---|
| D12 | LCD RS | Parallel 4-bit LCD wiring. |
| D11 | LCD Enable | Keep wires short for stable classroom demos. |
| D5, D4, D3, D2 | LCD data pins D4-D7 | Order must match LiquidCrystal lcd(12, 11, 5, 4, 3, 2). |
