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…
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[...]
This is Simple light controller circuit that is controlled light-activate. Use inverter gate IC-40106 as main,controlled switches phototransistors as sensor
