Blynk Fan Control
Motors · Board: Pi Pico · Day 22 of 100
Switch a DC brushless fan from the Blynk app through a relay on the Pico W. Phone-controlled cooling in minutes.

How it works
A button in the Blynk app sends a cloud message down to the Pico W, which switches a relay connected to the fan. The relay handles the fan's higher current while the board only handles logic-level signals. Phone-controlled airflow with two components doing what each does best.
What you'll learn
- Switching inductive loads
- Cloud-based actuation
- Relay driver stages
- Separating logic from power
