Something like that and then were going to put our switch right here. Can be 100k just to keep things calm and then a capacitor one microfarad. Okay, so then were going to take another resistor. These are 10k, so right here at this, node were going to be just about 2.5 volts. We simply use the led just to show whats going on here in the 30 ohm whoops now were going to do is were just going to take two 10k resistors and were going to whip up a little voltage divider here, and it is from that voltage divider That were going to feed this, so what you see we have is our 555 is going to be hanging on. You could easily substitute a transistor here or a relay whatever you want. Then simply, our output pin 3 in this case were sending it to a resistor, and then we have a diode in this case its an led. Pin 8 and pin 4, which is our vcc and our reset pin and both of those are going to get tied high of course, pin one our ground pin is gon na go low, pin five, which is our control voltage, is not connected the same with pin Seven is another not connected and then pin six and pin two theyre going to be connected over here to our switch. So lets start by drawing in our 555 timer were not going to be using many of the pins at all. This is our vcc, in this case, its plus 5 volts dc and theres our ground. This is probably about one of the simplest ways you could set up a 555 timer completely, all right so heres our circuit. Finally, not working there, we go thats, just pretty cool, so lets get that out of the way and ill show you the circuit, its really simple. The output is going over here, its currently syncing, just going through a 330 ohm resistor to the led, and it just makes stuff so much fun and simple, and you got there. Well, you got to know what that is its a 555 timer, nothing to it, but to do it were taking the output of the switch cone into a pin 6 and pin 2 our threshold and trigger pins. These are 10k resistors, making a little voltage divider here and this guy. How easy is that pretty cool huh? So what weve got here is attack switch capacitor. It is simply a single button, toggle circuit. What ive got for you today is a really neat little circuit.
