I am not fully understanding how transistors work. It would be great if someone could explain to me more thoroughly. As I understand it and have read transistors can be used as switches or to amplify voltages. Say then I needed to amplify 5v into 12 volts. How would I do this with a transistor...
This is a really simple question. My math teacher was explaining how if you drop a ball with some amount of air in it, it will never stop moving because it will always bounce half of the height of its last bounce. Then my science teacher said the force of gravity would eventually stop the ball...
Ok, I remade the whole circuit based on this.. not quite the same function but it still should go on and off. I wired it exactly like in the picture and now when I give the board power the LED lights up for a second then goes out and won't come back on no matter how long I leave it on. But when...
I pretty much put the whole idea of my calculations being wrong (with capacitor and resistors) by using a 470uF capacitor. The Led still light up like a Christmas tree. So, it has to be something wrong with how it's wired. I have gone over the circuit diagram a ton and I can't find what I did wrong.
Thanks for the welcome. Actually, there are two resistors there. I don't know if you missed it or what, but there is a 220k ohm and a 470 ohm resistor. Actually, I followed the data sheet for the timer. I am positive the way I have it set up should work which is why it is just so frustrating...
I just purchased a breadboard and components because I love tinkering with things. It's not for a class or anything more of a hobby, but I just needed some advice on a simple hello world like blinking led circuit. I have gotten down the basics of lighting up leds, and my second project I wanted...
