Imagine small suns making light in our garden at night. This Outdoor Garden Solar Lights Circuit works like small power house for our garden flowers. In daytime solar panel take sun energy and put it in battery. Then night time come smart circuit take that energy and make LED light ON so our garden stay […]
Electronic Gatekeeper Circuit
This small and Electronic Gatekeeper Circuit work like little guard for our door. It uses sensor to check if someone comes or goes from gate. Sensor can be like light beam or something we can step on. If person goes through without permission then circuit make alarm or send message to tell us. So we […]
Line Following Robot Sensor Circuit
This Line Following Robot Sensor Circuit work like robot eyes for follow line. It uses special sensor called IR or infrared to see black line and white ground. These sensor are like small light but light is invisible. Circuit look how much light come back then know where line is. Then this information goes to […]
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. It take strong electricity which is more than 5 volt and make it just 5 volt. 5 volt is perfect power for small electronics like those tiny computer boards for projects. Inside it got a special chip […]
Heat Sensor Circuit using Piezo Transducer
This Heat Sensor Circuit using Piezo Transducer is like small detective for heat. It uses special thing called piezo transducer which work like tiny electricity maker. When it get hot or cold it presses itself little bit and make small electric shock. The circuit look at this shock to know how much hot or cold […]
Automatic Parking Light Switch Circuit
This special Automatic Parking Light Switch Circuit makes car parking lights turn ON by itself. It look outside to see how bright it is. One light sensor is like LDR thing which check the light outside. If outside it become dark, more dark than set level then circuit turn ON the switch. Then electric connects […]
