The AC light dimmer circuit can control light bulb or speed AC motor, we use triac and SCR as main,and adjust potentiometer and switch,more circuits [...]
All controller, motor speed driver,switches,timer,sensor,and more : Timer switches • DC motor speed control • Delay timers • Light switchs • SCR controls • Light dimmers • Infrared remote control system • and more…
Tank empty! No water! You do not like it. Let's make automatic water level controller circuit. Keep constant water. Simple parts. You can do.
For learn about MOSFET. I recommend Time Delay circuit easy to make and long time and a few parts than normal transistor
This is IC 4060 Timer circuit. When rises time that is set, Suppose set 5 minutes time. after all time to 5 minutes. the circuit will emit a sound of buzzer once. [...]
This circuit prevents surges. From the opening is switched off or power failure. The damage to electrical appliances.
