Simple Micro Ampere Meter Circuit is like a special tool to measure small electric, normal tools too are strong but are not good for tiny current. But this one uses super sensitive meter microammeter or maybe special setting on multimeter to find very small electric flow like millionth of amp. Also, other parts like resistors […]

Simple Light Activated Alarm Circuit
This Simple Light Activated Alarm Circuit is like very sharp nightlight, it have small part called LDR which work like a tiny eye. Furthermore, when light goes away fast like someone is moving near circuit it make sound or light happen to warn us. Moreover, it also uses other parts like transistors, resistors, capacitors to […]
Simple Skin Biofeedback Circuit
This one is a special and Simple Skin Biofeedback Circuit which help people learn about skin, it uses sticky pads put on skin to catch small electric signal. Also, signal change when person feel more calm or is not calm; hence, the circuit show this change maybe with light or sound so person can learn […]
Simple Freezer Alarm with Buzzer Circuit
Simple Freezer Alarm with Buzzer Circuit is like small guard for our ice food, it uses one sensor, thermistor to check cold level. Furthermore, if freezer become warm too much then buzzer makes loud sound to tell us something is not right, like food is going to melt. Hence, with this indication we can do […]
Simple Solid State Relay (SSR) Circuit
Simple Solid State Relay (SSR) circuit is like ON/OFF switch but with more better and modern; not like normal switch with moving parts but this one uses special electronics parts like transistor or triac for turning ON or OFF. Also, it works quietly with no noise and last a long time, it is very good […]
Simple High Temperature Alarm Circuit using IC 555
Simple High Temperature Alarm Circuit using IC 555 uses one special chip called IC 555 which works like a temperature guard; also it keep checking temperature always. Hence, if its too much hot it make alarm sound like buzzer and tell us something is getting too hot, so we can know early and fix before […]
