How to Make Ultrasonic Remote Control Circuit
This ultrasonic remote control circuit can be used to switch and control any appliance ON/OFF through a relay in the receiver circuit. Written by: S.S. Kopparthy Using Ultrasonic Waves This circuit is a different one that uses ultrasonic sound waves whose frequency ranges from 40 KHz to 50 KHz. These waves can’t be heard by […]
Infrared Remote Controlled Door Lock Circuit
In this article I have explained about a simple infrared remote controlled door lock circuit which can be used for securely locking doors through unique foolproof IR frequencies. The proposed infrared remote controlled door lock circuit can be used for locking your main door, gate, garage door, shop or any entrance which may need a […]
Bluetooth Function Generator Circuit
In this article I have explained a simple Bluetooth function generator circuit which can be used for testing and troubleshooting various critical audio video equipment and gadgets Using a Function Generator Function generator is vital equipment for an engineer, professional, hobbyists, or someone who reached above “beginner level” in electronics. Function generator is an expensive […]
How to Connect an IR Photodiode Sensor in a Circuit
In this post I have explained how to correctly connect an IR photodiode in circuits such as a proximity sensor circuit. The explanation is presented in the form a discussion between one of the dedicated readers of this blog NVD, and me. Here’s the discussion which explains how to connect a photodiode in an electronic […]
Digital Clock Synchronized Programmable Timer Circuit
I have already discussed one programmable timer circuit in this blog earlier, the circuit involves the IC 4060 for generating the basic oscillations which is further used for generating the required time intervals, however this cannot be synchronized with an external clock. The following circuit was requested by Mr.Amit, here the concept makes use of a clock for acquiring the required base timing […]
