Ordered first parts; photoresistors, servos, Arduino, small breadboard.
|2-Wholesale parts||Purchased a variety of DC motors.||4 hours; day trip|
|3-Light-sensing and Chassis
||Got photoresistors working without incident. Had a problem finding 10k pulldown resistors, though. Found some in a drawer in a lab. Built the robot body.||4 hours|
|4-Arduino setup||Had trouble powering motors. Allegedly the digital pins on the Arduino can be used as a power supply. Was able to power an LED this way but the motors will only run off of the hard-wired power and ground pins.||5 hours|
|5-Code||Code completed; combined photoresistor code and control code. Tuning the control.||3 hours|
|6-Power failure||Hard-wired motors and implemented the rudder solution. Robot begins to malfunction with the added components being powered only through USB.||3 hours|
|7-Needs more funding||Works intermittently; needs more reliable power source.||2 hours|
