In this post I have explained how to build a letter box open indicator circuit, which indicates through an LED if the letter box had been opened either by the postman, or by somebody else! The idea was requested by Mr. Bill. I wonder if you could help me.I want to make an LED indicator […]

Tuned Radio Frequency (TRF) Receiver Circuits
A tuned radio frequency receiver (or TRF receiver) is a form of radio receiver which is made using a number of tuned radio frequency (RF) amplifier stages accompanied by a detector (demodulator) circuit to draw out the audio signal, along with an audio frequency amplifier for amplifying the extracted audio into a loudspeaker. This kind […]
Making an EGS002 Equivalent Board using Arduino
The EGS002 board is nothing but a combination of a microcontroller with a H-bridge driver like the IR2110. So if you are interested to build your own EGS002 equivalent board with exactly identical features, then you can do it using the instructions given in the following article. So, here we are trying to build our […]
Arduino 3 Phase Inverter Circuit with Code
An Arduino three phase inverter is a circuit which produces a 3 phase AC output through a programmed Arduino based oscillator. In this post I have explained how to make a simple microprocessor Arduino based 3 phase inverter circuit which could be upgraded as per user preference for operating a given 3 phase load. We […]
H-Bridge Bootstrapping
Bootstrapping is a crucial aspect that you will find in all H-bridge or full bridge networks with N-channel mosfets. It is a process in which the gate/source terminals of the high side mosfets are switched with a voltage that’s at least 10V higher than its drain voltage. Meaning, if the drain voltage is 100V, then […]
IC IR2184, IR21844 Half-Bridge Driver Circuit Diagram, Datasheet, Working
In this article we are going to learn about one very useful IC called IR2184 or IR21844. This one is a smart half-bridge gate driver IC which we can use for driving both high-side and low-side MOSFETs or IGBTs, mainly when we are making full bridge inverters, or DC motor controllers, or even induction heater […]
