There are times when GPS is not enough or available, such as when inside building where GPS signal is blocked. The aim of our project is to get direction using an alternative source: Light. It could be sunlight, flash light and etc. To achieve this, we arm two sides of our vehicle (wheelchair) with two photo resistors (inside homemade coffee cups). The sensed signal tells the direction of light. Then the vehicle driven from MSP430 with PWM control make turns accordingly based on the sensed signal comparison. One cool part of the project is that our code runs real time on Android devices runnning basic, communicating with MSP430 through bluetooth.
