SubscribeSimple LED flasher electronic project using transistors
Using this circuit diagram can be made a very simple LED flasher which offers the possibility of adjusting the frequency of LED flickering , and require a very small amount of current.
Transistors T1 and T2 form a relaxation oscillator whose frequency can be set between 1 Hz and 10 Hz, with potentiometer P1.
Period as the LED stay on is about 5 ms and can thus give a relatively high current value and thus produce intense pulses of light.
Circuit can be used with a supply voltages between 6 V and 15 V.
