So now we are talking about this digital IC called 4035 which is made using CMOS technology, that means it will use very low current and will give us high noise immunity. Inside this IC we have got 4 flip-flops which are arranged in such a way that they can hold and shift 4-bit data. […]

Morse Code Practice Oscillator Circuits
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: Anil Patil What is Morse Code Morse code is a legacy method of message encoding that uses rhythm and impulses to transmit telegraphic communication. Morse […]
DC Lamp Dimmer Circuit using IC 555
In this post I have explained 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 dimmer can be used for controlling the light intensity of any DC lamp having an operating voltage anywhere between 6 V and 12 V. The […]
Electronic Cricket Sound Generator Circuit
In this post I have explained 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 a device which generates a sound exactly similar to a real cricket insect. This is done using a set of oscillators configured […]
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 other BJT stage, so that one switches ON when the other switches OFF, and vice versa. This cross-coupling may be set up to switch either a […]
CMOS Astable, Bistable, Monostable Circuits Explained
In this article I have explained 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. We also learn how to enhance and modify these configurations to produce highly improved outputs from these multivibrators. When CMOS logic gates are configured […]
