1. PCB design and Line Follower

2. The goal of these labs was to be able to design a PCB using Eagle software of our robot car as well be able to create user defined componant libraries. The soldering skills as well as robot car knowlege was applied to the final goal of the robot car following a line.

3. Materials:

2x 100 ohm smt resistors

2x 10k ohm smt resistors

10k potentiometer

2x 741 smt Op Amps

Robot car

Line follower PCB

Soldering kit

Methods:
First four Eagle tutorials were completed, from designing a schematic to a user defined library. Next our Line Follower circuit was created using Eagle and submitted for manufacture from PCBway.com. Finally the componants were soldered onto the PCB and it was tested by mounting it on the robot car and repeating the line test.

5. Discussion:
This lab tied in the skill we have been learning all semster into a single project. The benchtop equipment was used to test the circuit on the board to ensure a proper solder job. Going forwad knowing how to design a PCB will be a valuable skill in the tool belt.
