I have a project in my electronic class that I need a little help in.
The following is the exact description for the assignment.
COMPUTER POWER- ON RESET SWITCH. For the following two assignments, start by connecting a SPDT switch so that its common terminal puts out either +5 V OR 0 V, as shown (see the attached picture on the left).
Now connect this output to your diode circuit, designed and constructed so that its output voltage will rise slowly (approximately 63% in 10 seconds) when the switch is turned to the up position, but will drop instantly to nearly 0 v when the switch is then turned to the down position.
Now do same as above, but the output voltage rises instantly when the switch is turned to the up position, but drops slowly when the switch is then turned to the down position.
Again, the diagram to the left below is what the instructor gave us to work with. The diagram to the right is what I think I need to complete the assignment. 63% is equivalent to two LED diodes that range from (1.7V -2.0V). As far as the slow rise in voltage, would that mean I would also need to add a capacitor? Any info would be great. I am going to lab tomorrow night to complete this assignment and would like to be prepared to construct the circuit before coming to class.
