In this article we will explore 3 different Morse code practice oscillator circuits, for generating exact replication of Morse code signals in the form of dots and dashes. Contributed By: […]
Blinking LED Circuit using LDR and Resistors
This is perhaps the most simplest looking LED flasher that does not depend on any semiconductor. This LED blinker circuit utilizes ordinary passive components like a few resistors, a capacitor […]
DC Lamp Dimmer Circuit using IC 555
In this post we will learn how to use the control pin#5 of the IC 555 to build a simple PWM controlled DC light dimmer circuit. The proposed DC lamp […]
Electronic Cricket Sound Generator Circuit
The post explains how to build a simple cricket chirping sound generator circuit using a single IC 4093 and a few other passive components. An electronic cricket sound generator is […]
Transistor Multivibrator Circuits [Astable, Bistable, Monostable]
A transistor or BJT multivibrator is a two-stage switching circuit that is configured in a cross-coupled manner. This allows each of the active BJT stages to be regeneratively cross-coupled with the […]
CMOS Astable, Bistable, Monostable Circuits Explained
In this article we discuss how to use the low-cost CD4001 and CD4011 quad 2-input gate CMOS integrated circuits in bistable, astable, and monostable multivibrator applications through forty different manners. […]
