Remote Controlled Ceiling Fan Regulator Circuit
In this article I have explained a few simple infrared TV remote controlled fan regulator or dimmer circuits using ordinary parts such as a 4017 IC and a 555 IC. The first concept uses a standard MOSFET based SSR for controlling the fan load and for easy and clean PWM signal operation from the IC […]
Understanding SG3525 IC Pinouts
In this article I have explained the pinout functions of the IC SG3525 which is a regulating pulse width modulator IC. So I have explained in details: Main Technical Features The main features of the IC SG3525 may be understood with the following points: Pinout Diagram of the IC SG3525 PinOut Description A practical implementation […]
Mains AC Short Circuit Breaker/Protector – Electronic MCB Circuit
In this post I will try to explain the making of a simple 220 V, 120 V AC mains short circuit breaker using an SCR and a triac combination, (researched and designed by me). The circuit is an electronic version of the normal main circuit breaker MCB units that we use in our homes. Note: […]
How to Send and Receive SMS Using GSM Modem
In this article I have explained, how to send and receive SMS using GSM modem which is controlled by Arduino. Let us see, what GSM modem is, how to interface it with Arduino, how to send SMS with the setup. We are also going to explore what are all applications we can achieve with GSM […]
