+Lab2 - Letter Counter
+Students: Andre Kuhlenschmidt
+     and: Jonathan Wegener
+
+Results: 
+
+During this lab we accomplished all the initial objectives. Our first step was to write up a diagram of how we wanted to wire our bread board. We then proceed to wire and test the seven segment display. Then we wrote a simple driver to display 0-31 in hex using the binary representations of numbers. After we had that working we proceed to wire the optical interrupter and treat that as a digital input in our program. After that we plugged everything together and wrote a letter counter which counts the number of times something passes in between the optical interrupter. 
+
+Difficulties: During this lab our only real difficulty pertained to the optical interrupter. We initially misunderstood the data sheet and tried to wire it with a 10K resistor. After we realized our mistake we quickly rectified it and everything worked as expected. 
+
+What did I learn: During this lab we learned about how to design circuit diagrams, how to wire a seven segment display, and how to wire and use an optical interrupter. We also learned how to properly read and use datasheets for wiring
