Led Dimmer Circuit 555. If playback doesn t begin shortly try restarting your device. The circuit is designed around a popular 555 timer ic which acts here as an astable multivibrator.
Before we get start building a 1 watt led dimmer circuit first consider a simple circuit as shown in figure below. If playback doesn t begin shortly try restarting your device. Then the pwm pulses drive an n channel power mosfet.
