How to Control LEDs on the Arduino - Circuit Basics

The same concepts used to control LEDs are used to control motors, relays, buzzers, and many other devices.

Temperature controlled LED circuit. Student. Arduino. Blinks every 3 seconds at or below room temp. When too warm it shuts off. Very basic example of temperature monitoring/control. : r/electronics
