Light Sequencer 5 Channels 220V


Posted on Feb 6, 2014

This circuit controls five outputs 220V. Potentiometer change speed and a switch select effect (one direction or both directions). The circuit has a divider by 10 (4017), a transistor oscillator (2N2646), the power stage and power supply. Each pulse on pin 14 of 4017 advance to the next (the order is: 3, 2, 4, 7, 10, 1, 5, 6, 9, 11 - In that orde

r - and then repeat). If the integrated pulse is applied in pin15 back and resumes on pin 3. 4148 diodes prevent the return of power to the IC. Capacitors at the bases of transistors BC548 (47 µF) (but this value can be changed and should be tested) when higher the value output will remain switched on and off to turn off more smoothly.
