Dimmer with a Micro

Dimmers come in many varieties — you’d think. Still, the author did not find what he wanted. So it was back to the drawing board to design a dimmer circuit with the exact personal requirements. The result is a project that’s easy to add to the existing electrical installation as well as simple to operated using existing light switches. The design is for 230 V, 50 Hz AC power lines and our US and Canadian readers are expressly invited to rework it to 110/115 VAC, 60 Hz.

Features

- Dimmer function using phase angle control
- Simple to set (can also be permanently set)
