optocoupler circuit

The optocoupler U1 isolates the ESP-01 electronics from the lethal mains voltage. The PWM signal comes from the ESP-01 microprocessor and switches the infrared diode in U1 On and Off. When the diode is on, the emitter(4)-collector(5) transition of the transistor in U1 will conduct, causing the gate of Q1 to become > 10 volts, closing the MOSFET switch and causing the LED lamp gets voltage.

However, most of his working life he has worked in automation where he has worked in just about all disciplines from programmer to project leader and project manager. Willem was one of the first Dutchmen with a micro-computer (KIM-1, 1976) at a time when the PC had yet to be invented. Nowadays he is mainly concerned with the design and production of small electronic circuits with microprocessors. His 'mission in life' is to make people enthusiastic about making their own electronic circuits, microcomputers and programming.
