555 IC Based Schmitt Trigger Circuit
555 IC Based Schmitt Trigger Circuit is a small project. It work like comparator and comparator is ON/OFF when input cross the voltage. Noise make output jump and Schmitt Trigger stop this. It have 2 limit: high and low. Input goes high then output is ON. Input goes low then output is OFF. Between them […]
Two Star Flasher Circuit with 555 IC
This simple article is for Two Star Flasher Circuit with 555 IC. Main part is 555 timer IC which works in astable mode. In this mode IC give continuous square wave pulses. These pulses make two lamps blink one by one like star. Blink speed depend on resistors and capacitor values. Transistor are used for […]
