Pulse Generator Circuit Diagram Welcome to my channel! In this video, I'll show you how to create a simple and effective clock circuit or pulse generator using the versatile 555 timer IC. W In this video you will learn how to make a pulse/wave generator with varying frequency with help NE555 timer IC.For more information and circuit check the ar The STM8S103F3 has three timers, a basic timer, and general purpose timer and an advanced timer. The advanced timer (TIM1) can be used as a One-Pulse timer, just what is needed. When a One-Pulse timer is triggered it counts from zero to the value set in the Auto Reload Register (ARR) and then stops, until it receives another trigger.
This is sometimes called a one-shot circuit. The time it stays HIGH is decided by the size of a resistor and a capacitor. The higher the values, the longer it stays HIGH. If you connect a buzzer to the output, you can create an alarm circuit that is triggered for example by a window being opened. 555 Timer One-Shot Example Circuit These pulse generator circuits—a.k.a. an astable multivibrator oscillator circuit—employ a 555 timer IC, NE555 or LM555, in its astable (free-running) mode. These types of circuits are often paired up with digital logic circuits. The 555 timer IC is also very popular and simple to use, with a small eight-pin package and a supply voltage range of 4.5V to 16V.

This is a pulse generator with adjustable duty cycle made with the 555 timer IC. The circuit is an astable multivibrator with a 50% pulse duty cycle. The difference from the standard design of a 555 timer is the resistance between pins 6 and 7 of the IC composed of P1, P2, R2, D1 and D2. The diodes D1 and D2 set a definite charging time for C1 For comparison, in figs 10 and 11 I set up another 555 timer on my breadboard, identically to the setup of the first 555, but I used a 0.47uF capacitor instead of a 1uF. I calculated the duration of the pulse for this new circuit: t = 1.1*R*C seconds t = 1.1*5100*0.00000047 t = 2.64 ms, approximately half of the duration of the first 555 timer How the Circuit Works. Any one of the total four gates can be used to produce an oscillator with a variable duty-cycle and a set frequency. The RC time-constant of this network that has a capacitor C1 and resistor R1+P1 helps in determining the pulse duration.
