This is a motor protection circuit. It will protect the AC motor burn out because under voltage input. The principle is simple, it will check for voltage at all times. Normal voltage is 220V AC. If the voltage falls below a preset. Relay will not work and the LED is a warning.
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…
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.
This is IR appliance switch circuit using any infra-red remote control.Can choose to work or SPST switch-normally open pushbutton switch.One channel output.
This is The small tweeter speaker protection circuit It can be packed into any speaker cabinet, and does not require a power supply as well. [...]
This infrared remote control can control working of 2 channel or can use to control two Electric appliance, each one on-off freely and a maximum of 300 watts on Control…
We try to apply a JK Flip-Flop to Light sensor switch circuit experiment. We use MC14027 or CD4027 or TC4027 as CMOS-IC that inside has JK-Flip-Flop
It is a H-Bridge motor driver circuit that popular, high performance,to moving of a robot,designed by mosfet or transistor to control rotating of motor[...]
