555 Timer IC - Low Frequency Pulse Generator Circuit 45 related questions found Is a pulse generator circuit? A pulse generator is eitheran electronic circuit or a piece of electronic test equipment used to generate rectangular pulses. Pulse generators are used primarily for working with digital cir...
This schematic shows an astable 555 timer IC pulsing an LED on and off: 555 timer uses R1, R2 and C1 to generate a clock signal. Transistor Q1 amplifies the pulse to drive LED D1. R3 limits LED current. Voltage Divider Circuit
What is PWM (Pulse Width Modulation)? PWM stands for Pulse Width Modulation; we will get into the reason for such a name later. But, for now understand PWM as a type of signal which can be produced from a digital IC such as microcontroller or 555 timer. The signal thus produced will ...
A 555 timer IC1 is used in astable mode i.e. with the free-running multi-vibrator condition the frequency of which is to be varied by a variable resistor. This output is used as clock pulses for a decade counter IC2. Running Light using IC4017 and IC 555 The output of the counter ...
In this tutorial we will learn what is Schmitt Trigger and how it works. The Schmitt Trigger is a logic input type that provides hysteresis...

The circuit is consists of twoNand gates(74HC00 IC) forming aSR flip flop. As you can see in the circuit diagram whenever the toggle switches to the A side the output logic gets ‘HIGH’. Here, we have used an oscilloscope to detect the bouncing. And, as you can see in ...
However, if a low logic voltage is applied, the output will instead be at a high impedance state, because the NPN transistor will be acting as an “open circuit”. This effectively prevents any current from flowing through the IC, and so no current will flow through the coils of the ...
