Simple Time Delay Relay Circuit
Can anyone think small timer for their electric things? This Simple Time Delay Relay Circuit work like stopwatch for power; it waits for some time before turning ON or OFF something like light or motor. Also, this wait time can be same always like 5 second or can change using timer knob, main reason to […]
Simple Multi Siren Tones Circuit using IC UM3561
This Simple Multi Siren Tones Circuit using the UM3561 chip works like a small sound box for emergency vehicle sounds. Moreover, the special UM3561 chip can create many siren noises, such as the “wee woo” sound of a police car or the fast tone of an ambulance. Furthermore, it only needs few more parts and […]
Simple Temperature Controlled DC Fan Circuit
Simple Temperature Controlled DC Fan Circuit is like smart fan, which uses special sensor to feel heat around; so when place, it get too hot then circuit makes fan run fast like turning AC high. Therefore, if the place cools again then fan slow down or stop to save power, hence, this circuit uses parts […]
Simple 220V White LED Flood Light Circuit
This Simple 220V White LED Flood Light Circuit is like a small power machine for big bright light, as it takes normal home current 220V and make those special white LEDs glow. Also, the circuit works like converter and change big voltage to small one which are good for LEDs. Inside small parts like resistors, […]
