Wiring up the Line sensor
Attach the following wires to the pico
| Pico GPIO Pin | Line Sensor | Comments |
|---|---|---|
| 3.3v out | V+ | Solder the end of a female dupont cable to the 3.3v out on the Pico |
| GND | GND | Solder the end of a female dupont cable to the ground (GND) out on the Pico |
| GPIO 17 | Signal | Solder the end of a female dupont cable to GPIO 17 on the Pico |
MicroPython code
Using a line following sensor is fun and simple! After you attach the special wires (called Dupont connectors) to your robot, you can make it work with some cool code.
Remember, we need to slow down our robot’s speed so it doesn’t go too fast and miss the line it’s trying to follow. Also, we want our robot to check the line very often, so it can stay on track while moving along the line.
