lets to see Automatic Op-amp night light circuit using IC-741. It is also very simple. As my feelings It has high sensitivity more than one,high accuracy.
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…
To Control speed DC motor easily with a few parts in circuit.
The super dimmer it is certainly better than the normal dimmer you are using now. It would be better, however, to try to prove it. Let's see how it works circuits.
Automatically change the dark corner of the house to be brighter with LED. No AC main but can run with battery solar charger. Do not doubt that How does it work or is it easy? Let's learn.
See simple Infrared Intruder Alarm circuit. Even it is best. But it is a good teacher to learn electronics. Using infra-red system.
See: 555 PWM DC LED dimmer circuit in 12V source. For a lot of loads even control the speed motor. Nearly with loss and high performance
SEE DIY compressor time delay circuit. Protect your compressor when power outage and Electrical fluctuations. Using normal parts and cheap.
