Two-way relay

Introduction: Relay: It is an electrical control device. When the change of input quantity (excitation quantity) reaches the specified requirement, it causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system (also called input circuit) and the controlled system (also called output circuit).

Schematic PCB

Dimmable light STM8

Introduction: The PWM wave is output through STM8, and then the brightness of the LED light is controlled through the change of the ADC sampling value. When the light is strong, the brightness of the LED light becomes weaker, and when the light is weak, the brightness of the LED light becomes stronger.
