In this post we elaborately study how to make an Arduino based PWM signal generator circuit, which can be set or adjusted with a potentiometer or a pot to any preferred duty cycle ratio. WHAT IS PWM? pwm or pulse width modulation as the name itself suggest is modulation of width of the pulses i.e. […]

Generator/Alternator AC Voltage Booster Circuit
In this article I have explained an alternator power booster circuit which was unveiled by one of the keen followers of this blog, Mr Michael Mbamobi. I have explained more about the details. Technical Specifications There is this circuit I want to show you. I want to show you the circuit through Homemade Circuit or Brighthub. I […]
2 Tone Ringtone Generator Circuit
The IC LS1240A from SGS Thompson is specifically designed for generating a 2 tone ringtone generator circuit. Thus the IC specifically becomes suitable for landline telephones for producing the ringtones when a call is received. However with little modifications the IC can be easily utilized for normal applications, in circuits where a double tone alarm […]
1 Hz to 1 MHz Frequency Reference Generator Circuit Diagram
This circuit is an universal frequency generator which you can use in numerous frequency and time period testing applications. It is primarily well suited for a gate pulse generator in frequency counters. The circuit is capable of generating an entire range of reference frequencies such as 1 Hz, 5 Hz, 10 Hz, 50 Hz, 100 […]
7 Easy Sawtooth Waveform Generator Circuits using UJT, IC 555, and Transistors
In this post I have explained how to build 7 types of easy sawtooth generator circuits, using BJTs, UJTs, and IC 555. In a sawtooth waveform the voltage increases slowly in a slanting manner or diagonally, then as soon as it reaches the peak, the waveform voltage suddenly drops to zero. Once it drops to […]
9 Simple Sine Wave Generator Circuits Explored
A sine wave generator is actually a sine wave oscillator circuit which generates an exponentially rising and falling sinusoidal waveform. The 9 simple sine wave generator circuits presented in the following article are easy to build, since they incorporate a small number of ordinary electronic components, and can be used for generating an exponentially varying […]
