Light Sensors

Next, in preparation for the final project, we started using the small light sensors. We decided to mount them on either side of the front of the car, so that the contrast between readings could indicate which side of the car the light was on. But, before we could get any readings, we had to get another 10Kohm resistor so that both ports could have the same resistor.

The configuration of our light sensors.

When both were connected through the same size resistor, the readings from the right and left sides were very similar, usually within 30 units.
Next, we tested the readings when a flashlight was at several positions, intending to make the car be able to follow the light of a flashlight.

However, we didn't have time to program the car.
