Our downscaled model features a electrified track and an Arduino-controlled vehicle.

There are Arduino controlled installed on both vehicle and track.

 When the vehicle is off-track, it is powered by onboard battery and controlled by its own Arduino chip.

 When the vehicle is on-track, it draws electricity from the track. The supply of electricity is controlled by a chip connected to the track.

The car utilizes 4 DC motors, which enable precise braking and adequate power

//—————————————————————————————-

// myCode();

// This is the tab where student programming is done.

// A list of available function calls are listed in detail under tab “00_Student_Functions”

//

// Note:

// (1) After running your program do not turn the controller off, connect the controller to a computer, or

//     push the reset button on the Arduino. There is a 13 second processing period. In

//     post processing, data is stored and battery recuperation takes place.

// (2) Time, current, voltage, total marks, forward marks, and backward marks traveled are recorded approximately

//     every 60 milliseconds. This may vary depending on the vehicles operational tasks.

//     It takes approximately 35-40 milliseconds for each recording. Thus when programming,

//     code complexity may not be beneficial.

// (3) Always comment your code. Debugging will be quicker and easier to do and will

//     especially aid the instructional team in helping you.
