During the first week the group soldered wires to the photodiode and IR LED and constructed the LED driving circuit along with the photodiode circuit to voltage conversion circuit.  The group was able to read voltages using the arduino serial monitor and will now proceed to interfacing the serial monitor with matlab as well as creating code to control the servo motor and stepper motor.

Attached is a picture of the circuit diagram used to construct the current to voltage conversion circuit for input into the arduino.
