What it is¶
A small brushed DC motor mounted on a driver module. Your ESP32 can turn it on, turn it off, and vary its speed using PWM. Unlike the servo (which rotates to a specific angle), the DC motor just spins continuously.
DC Motor vs Servo Motor¶
| DC Motor | Servo Motor | |
|---|---|---|
| Motion | Continuous spin | Rotate to specific angle (0°–180°) |
| Speed control | Yes (via PWM) | Indirect (by changing angle over time) |
| Typical use | Fans, pumps, wheels | Robotic arm, gates, dials |
What you'll build with it¶
- Cooling fan for a smart climate project (pairs with DHT11 — turn on when it's hot)
- Wind turbine animation (pairs with the Solar Panel)
- Simple motorised vehicle
