Project #6: Opto-Couplers
This project caused me a little bit of grief, especially because I
believe that it's dead technology... Oh well, did the work anyway...
1. Remove one end of the resistor R5. This shuts off the opto-coupler. What is the effect of this?
The 7 segment LED turns off.
2. Change the settings of the binary switches and reconnect R5. What happened?
It turned back on displaying the binary number on the switch.
3. Is this what you expected?
Yes.
Any questions?
