Topic: Toggle button NE555 trigged over Arduino (Read 2474 times) previous topic - next topic

Hi all. the transistor actually does its job without problems if the ouput of ne555 corresponds to high. each time you press the button, but the polarity (the collector and emitter terminals) therefore, the diode is used to prevent reverse current collector emitter circuit. Maybe then I can not explain, but if you have a way to do a test with the components you will realize the thing. Thank you all for your interest, I felt it was easier.
