555 astable multivibrator circuit diagram
The circuit diagram illustrates the 555 timer (or 556 timer in half configuration) configured in astable multivibrator mode. It features three resistive and capacitive elements connected as shown. In one-shot mode, the trigger terminal (pin 2) is connected to the...
555 timer circuit temperature monitoring system
This 555 timer circuit temperature monitoring system project can monitor temperature at up to four points. The system allows for the selection of whether the alarm should be triggered when the temperature increases or decreases, depending on the resistance R10....
Electronic Roulette wheel with 20 LEDs and with 36 LEDs
In this electronic roulette wheel, the 555 timer functions as a pulse generator with a fading frequency. The 4017 counter activates LEDs sequentially in the selected string, while a D-type flip-flop (4013 IC) serves as a divider by two to...
555 timer touch activated alarm circuit
This is the circuit diagram of a touch-activated alarm system that remains operational during power outages. The alarm system is triggered when someone touches the designated touch plate. A notable feature of this circuit is the automatic battery activator, which...
Sequential Led Flasher With Reversible Direction
A 555 timer controls a 74190 up/down counter. The 74190 drives a BCD decoder driver 7442. The 7476 is utilized to reverse the count at 0 and 9, resulting in an up-down-up-down counting sequence.
The circuit utilizes a 555 timer configured...
