I've read the text before, but I need to know how practically add or connect display to the circuit...which elements I have to buy for display the result and how to connect it!
:lol: obviously you wouldn't be constructing any display? The DMM simply means a 'Digital Multi-Meter', which if you check topped the list of apparatus you'll be bringing for the lab. You'll be using it to check for the voltage levels corresponding to your light intensity.
Constructing the digital multi-meter i tell you is a major project on its own.
wellll... i wouldn't call this a major project, it was by the way titled as a laboratory work - one that you could do under 30 minutes in one sitting. you could get a digital multimeter for < $10 i think.
As everyone has been trying to tell you:
From the project description:
A. Equipment:
1. Digital multimeter (HP34401A) THIS IS THE DISPLAY!
2. Triple output programmable power supply (HP E3631A): set at +9V, -9V (with 100mA current limit)
3. Protoboard and screw drivers
4. Blue box with cables and connectors
5. Resistors: Four 1kOhm, and others (values from Pre-lab)
6. Potentiometers: one 1kOhm, one 50kOhm
7. Three 741 op-amps
8. One red LED
9. PC
10. Electronics Workbench (Optional)
11. Labels
Oh come on now! Are we back to this "avatar choice" issue again? Where's your sense of humor? If anyone on this planet can make Mr. Bin Hidin' look even more stoopid, Rowan Atkinson sure can. Go lightly.... I know you have it in you from some of your replies I've read. Peace - brother!
