Low Cost Pulse Generator circuit Circuit Diagram 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 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
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 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
Pulse Generator Using a 555 Timer : 3 Steps Circuit Diagram
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.
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
