Summary of Led dimmer 2 channels using Attiny13 microcontroller
This article describes a 2-channel LED dimmer circuit built around the Attiny13V microcontroller. The device supports five program modes, including dimming two channels individually or together, and three distinct blinking modes with speed control. The design utilizes a simple hardware setup featuring voltage regulation, capacitors for stability, resistors for current limiting, and transistors for channel switching, all controlled via a single button and potentiometer interface.
