This is a prototype of a magnetic sensor BoosterPack for the TI MSP430 Launchpad. http://www.youtube.com/watch?v=whgsB5hb-Pk The board has 3 Hall-effect magnetic sensors that sense a magnetic filed in the z-axis to the sensor. The BoosterPack has a latched output sensor (on/off by changing magnetic field direction), unlatched output sensor (on/off by changing magnitude of magnetic field), and analog output sensor (output follows strength of magnetic field). The sensor outputs are connected to analog input pins of the MSP430 LaunchPad. 10 LEDs are connected to digital output pins of t
