Controlling a relay with microcontroller - how does it work, what should you check out for? - German

Friends, in this video I will introduce you two circuits with which you can control relays with different coil voltages via a microcontroller (Arduino, ESPxx ...). I explain how the circuit diagrams work and which protective measures are necessary, as well as something about the electrical isolation of the circuits. As always, all information, component values ​​and the circuit diagram are available on the blog: www.aeq-web.com/relais-mit-mi...
