hey guys:
I am new to electronics and this problem is getting me very confused, your help will be appreciated.
It is a design problem with a 555 timer. When you push button PB 1, a 6V dc motor starts running, and pushing PB 2 causes the motor to stop.
The question that I don't even know its meaning is: "Justify that a negative pulse to ground is input to the particular 555 input when a push button is pressed. (The trigger and reset inputs have high resistance.) Which push-button type should be used, NO or NC? And what curren limitation is placed on the motor?"
any clue on what to do here? Thanks.
