LED Color Fade Effect circuit diagram

Posted on Feb 5, 2014

This is the circuit of LED color fade effect. Just like the name of the circuit, the light intensity of LEDs in this circuit will fade from high intensity to low intensity and then off. 30 uF condensator and the resistor marked with blue 100k control the speed of the fading. You can replace the 100 kilo ohm resistor with 100k linear potentiometer

so you can adjust the speed any time. LM324 is an OP-Ampamplifier. There 4 op amp, and we just use 2 op amp in abovecircuit diagram. You may use the other 2 op-amp to build another similar circuit. Transistor is BC547 and the led isultra brightred with 220 ohm resistor in series. We aim to transmit more information by carrying articles.
