In January this marks the start of us building the white line sensor. For this we constructed a breadboard of the materials use to get this voltage. We then measure the threshold voltage for when the light reflects on a black surface compared to where the light reflects on a white surface.

To do this we put the measurement of Vout, which is between a resistor and a LDR, to test the different threshold voltage. We then create a plan on how we would lay it out on a circuit board before we then go on to solder it on the board.
