Lab 2 - Sensor to Arduino board interface

Tasks one through four have been completed.

Simple circuits have been designed for each sensor in order to connect the sensor to the arduino board. Sensor functionality was tested and verified. From there the digital signals from each sensor; hall effect, FSR, photocell, and potointerrupter were all taken into the ardino board, and having the ability to affect the blinking LED ensured us of a working sensor to arduino board interface utilizing both digital inputs and digital outputs on the board.

Bringing in analog signals to the arduino board from the petentiometer, the photoresister (configured as a voltage divider), and the hall effect sensor was a simple task. However, understanding how to use EEPROM to write and read accross the serial port has been challenging. We currently are able to write data. Then we have separately run the EEPROM read script in order to obtain values stored in the boards internal memory.

A video of the potentiometer controlling the LED is below as an example of our progress.
