I'm in high school computer engineering, and I'm experimenting with the 555 Timer chip on my own. I'm using the Electronic Experimenter Box.
- Pin 8 is connected to +5V
- Pin 1 connected to ground
- LED1 is connected to Pin 3 and +5V
- LED2 is connected to Pin 3 and ground
At first, LED1 is off and LED2 is on. When I connect pin 6 to +5V, LED1 turns on and LED2 turns off. When I connect pin 5 to +5V, LED1 turns off and LED2 turns on.
The weird thing is that when I touch pin 6 with only 1 end of a wire, it produces the same results as if I connected pin 6 to +5V. The other end isn't connected to anything either and I'm not touching any metallic part of the wire. What's going on here?
