SCHEMATIC DIAGRAMHere we will see the schematic diagram of the project and all its values to be able to do it both on the breadboard or on the pcb
Many times we have a hard time making circuits without the data sheet of a main component. This is the case of a 555, we know that with this device we can carry out many applications, pulse generators, delay generators, etc. But what would happen if I wanted to make a disconnection time delay circuit with a single pulse? Let's put ourselves in the case that one day we don't have this integrated. Well, in this video we will learn how to make the turn-off time circuit with a single pulse, just with a few resistors and a capacitor without using the 555 or another similar component, in addition, we will be able to regulate the duration of the turn-on time after having pressed a button.
