Simple Led Driver Circuit using IC LT1932
This Simple Led Driver Circuit using IC LT1932 chip works like special power for LED lights. LEDs do not like too much or too little power so this circuit gives just a right amount and then LED shine good and live long. Also, LT1932 chip work like traffic police it controls power flow nice and […]
Simple Light Operated Relay Circuit
Simple Light Operated Relay Circuit work like small auto light switch, as it uses special sensor like LDR or photo diode which work like small eye. Furthermore, when light appears sensor gives signal to the circuit and then circuit turn the relay ON or OFF; and this help for turning outside light at night or […]
Simple Rain Sound Effect Generator Circuit
This small and Simple Rain Sound Effect Generator Circuit it like a rain sound maker in box, as it uses electric parts to make sound and almost same like real rain drop. Also, this soft sound are good for many things like background music or sleep timer or help us in dreaming. So next time […]
Simple Adjustable Zener Diode Circuit
Think like small switch which controls how much voltage go through. A normal Zener diode works like a fixed switch that allows electricity to pass only when the voltage rises above a certain level, but this Simple Adjustable Zener Diode Circuit works more like a flexible dimmer switch. We can also change voltage level using […]
Simple 5V Switch Mode Power Supply Circuit using IC LM2674
This Simple 5V Switch Mode Power Supply Circuit using IC LM2674 work like charger for electronics but better; as it take strong electricity which is more than 5 volt and make it just 5 volt. A 5V supply provides perfect power for small electronic devices and project boards, also this circuit uses a special chip […]
