Self-driving Toycar: Difference between revisions

Revision as of 21:43, 27 February 2017

Remove the screws on the bottom and remove the top.
Cut of all the wires going to the BCP, as close as possible to the PCB. (make sure the power switch keeps working and that it is off)

IMPORTANT! disconnect the (green) jumper marked PWR right next to the screw terminal marked EXT_PWR
Connect the motors to driver/h-bridge.
(Add diagram with pin names. Dependent of which driverboard we're going to use.)
Connect the cars' battery to the driver
Connect (solder) the driver ground to Arduino ground

Test > Sample code to test motors over serial connection.

Module  ->    Arduino   
- - - - - - - - - - -
VCC     ->    5V
GND     ->    GND
A0      ->    A0

Ideas:

Add ultrasonic sensor to avoid collisions
The car now always steers either left or right. Can we add straight ahead?
Try to make the steering proportional to the error in the line sensor
Make the light sensor trainable. (Maybe add a button to switch between training / driving mode?)

Connect the line sensor analogue output to A0. GND -> GND VCC -> 5V
