For some time now, I've wanted to build a circuit on my breadboard that uses a button to turn an LED on and off. When the button is pressed, the LED should light up and remain lit until the button is released. When the button is pressed a second time, the LED should go out…
Hello, I'm looking for a button like this. It doesn't matter whether it says door, bell, light, or nothing at all. Does anyone know where I can get these buttons, what year they're from, and what brand? thanks in advance
So not a toggle switch but a toggle button. I can't think of anything other than connecting it as a normally closed or normally closed contact, depending on what is needed. Greetings 🙂
So, I have a completely normal push button with two connections. There's a glow lamp on both connections, which should light up when the light is off and go out as soon as the light is pressed. My impulse switch has contacts A1, A2, 1, and 2. How do I connect it like this? A…
Hello, I would like to buy a micro switch with printed circuit board. Can it be put on a breadboard, or is that not possible?
Hello, I need a circuit in which a button is pressed for x seconds, resulting in a pulse of the same length. I also want to be able to quickly and easily adjust/change the length of the pulse. A new impulse may only be generated when the button is released and then pressed again. Unfortunately…
So, I want to be able to switch something using a contact rail. So, the train travels over contact rail A, emits a brief current pulse, and the relay should remain in the other switch position, allowing current to flow through it, until the train later travels over contact rail B, which emits another current…
Hey, Quick question: If I connect the 3.3v output to a gpio input with a switch in between and press the switch, will I then fry the Pi?
