The following post illustrates a simple light toggled/operated remote control circuit, which can be activated by an ordinary flashlight or more effectively through a laser beam unit (key chain type). The circuit idea may be understood with the below mentioned points: How the Circuit Functions Transistor T3 along with the associated parts and the LDR […]

Infrared Remote Control Safe Lock Circuit
A simple, cheap yet highly effective infrared remote control safe lock circuit can be studied in the following post. Using IC LM567 The LM567 IC is one of my favorites simply because it’s too versatile, and becomes applicable in most of the crucial circuit concepts through hassle free configurations. One such crucial yet simple IR […]
Make this Touch free Faucet Circuit for Hands-free Tap Control
A very simple touch free faucet circuit or touch free automatic tap circuit can be built using as little as an IC 555 and a few passive components, in order to implement a contact less water supply operation from the attached facet or the tap. Drinking Water is Precious Pure drinking water which we normally […]
Triac Phase Control using PWM Time Proportional
A triac phase control using a PWM circuit can be useful only if it’s implemented using a time-proportional format, otherwise the response could be haphazard and inefficient. In a few of of my earlier articles as given below: Simple Remote Controlled Fan Regulator Circuit Push Button Fan Regulator with Display Circuit Dimmer Circuit for LED […]
Remote Control Infrared Tester Circuit
We all use remote control handsets for controlling various household devices such as TV, AC, Music systems, curtains etc, and sometimes we seem to have problems with these devices, or even a newly purchased remote controller unit occasionally seem to malfunction, and identifying the issue becomes quite difficult for us. This simple 2 transistor infrared […]
Multiple Appliances Remote Control Circuit
In this post I have explained a simple IR remote control circuit which can be used for controlling many appliances independently through a single transmitter handset. The idea employs ordinary components like IC LM567, IC 555 and does not incorporate microcontroller devices. The idea was requested by Mr. Saeed Abu and also other dedicated readers […]
