Logochip - Challenge 5: Shadow Detector

For this challenge we had to wire into the photocell which was not too hard. But was also had to use the oscilloscope again. Which was, again, a problem. I just don't think we are getting too used to this oscilloscope thing. But we had to ask for help again in getting the oscilloscope to work correctly. But after that things went smoothly. This challenge was really similar to detecting edges with a switch. We just had to read what the values were when there was a shadow and when there wasn't a shadow. For this challenge, we counted how many fingers passed over the photocell which was similar to counting how many times we pressed the switch.
