Automatic Doorbell Light Circuit is like small help friend for our door; like when someone presses doorbell light turn ON by itself near button. Also, it help us to see button easily and specially in night or dark time; so we can open door fast and can be safe for visitor. Circuit Working: Parts List: […]
Automation Circuits
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 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 […]
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 and if person goes through without permission then circuit make alarm or send message to tell us. So […]
Line Following Robot Sensor Circuit
To begin with, this Line Following Robot Sensor Circuit work like robot eyes to follow line. Furthermore, it uses special sensor called IR or infrared to see black line and white ground. Also, these sensor are like small light but light is invisible. Then circuit look how much light come back then know where line […]
Simple Water Level Indicator Circuit using IC ULN2004
This Simple Water Level Indicator Circuit using IC ULN2004 work like small helpers for our water tank; as it uses one special chip named as ULN2004 to control many things together. This chip can work with big electricity but here it only control lights, the lights show how much water is inside the tank. So […]
