One LED flasher circuits
These circuits are simple One LED flashers that use transistors as the main (first circuit), the transistor UJT (second circuit) and IC Op amps (the Third), Read more below. 1. Using transistors as base The capacitor C1.Resistors R1 frequency generator to Q1. Which acts like a switch.then used Q2 to be the current increase. Operation of this circuit from capacitor C1 through R2 and LED1. Until the voltage drop at C1 increases,Q1 to the value that work. As a result, the current Q1. The current through pin E and C stand to cooperate with the Q2 Q2 B’s conduct as …
