In this post I have explained a simple automatic PIR controlled solar garden light circuit which will switch ON the LEDs only under two conditions: when it is completely dark and when a human being is detected in the vicinity. The above feature of the circuit ensures that the LEDs are turned ON only when […]

3 Laser Beam Controlled Circuits Explored
A compact, battery-powered transmitter emits a LASER beam when the control push button is activated. The beam is frequency-coded to provide a maximum level of reliability in transmission. The receiver can be located at a considerable distance from the transmitter (up to several tens of meters). The light beam, by definition, remains highly focused, and […]
Simple Remote Controlled Curtain Open/Close Circuit Diagram
In this article I will explain a simple curtain controller circuit designed by me which can be used to control the opening and closing of a curtain through a remote control. Overview Referring to the circuit diagram in your screen, we can see there are just two relays employed for implementing a remote controlled opening […]
Mobile Phone Controlled Door Lock Circuit
Controlling your door lock through your personal cell phone was never this easy. Learn how to build a simple electronic circuit that will help in converting your ordinary door lock into a high security door lock which can be now controlled through your own cell phone. Your ordinary door lock can be now very easily […]
Remote Controlled Fish Feeder Circuit – Solenoid Controlled
In this design a solenoid is operated using an IR remote control, which in turn toggles the fish feeder mechanism. In this article I have explained how to make a simple infrared controlled fish feeder circuit. The idea was requested by Mr. Harishvar. Technical Specifications I just want a circuit which should turn on when […]
Temperature Controlled Relay Switch Circuit
In this article I have explained a simple temperature controlled relay circuit which can be switched ON/OFF depending on the temperature on its temperature sensor. Meaning, when the temperature on its temperature sensor rises above a set threshold point, the relay switches ON, and when the temperature drops below the threshold, the relay switches OFF. […]
