The comparator circuit was controlled through a photo resistor. Depending on the amount of light hitting the photo resistor the state would be either high or low. A relay set up as an H-Bridge would transfer high and low two forward or backward movement of the motors. | The comparator circuit was controlled through a photo resistor.

Originally we wanted to mirror this circuit on the breadboard so both motors could be controlled independently. Unfortunately we were missing a second Transistor (TIP-127) to be able to finalize our plans that weekend. | Originally we wanted to mirror this circuit on the breadboard so both motors could be controlled independently.

Although not being able to complete our second assignment to the extend we had originally imagined, we somehow had the feeling our vehicle was developing it's own character in a way. | Although not being able to complete our second assignment to the extend we had originally imagined, we somehow had the feeling our vehicle was developing it's own character in a way. | ||
e.g. it could be programmed to be shy of the dark, and stop driving when it leaves a well lit space. | e.g. it could be programmed to be shy of the dark, and stop driving when it leaves a well lit space. | ||
