It was just myself and Helen at the Tinkerers meet up today. We had a look at my Arduino robot, which Helen has taken home to work on.

We spent a good deal of time testing Helen's Dragstar car.

This was the first opportunity to mark out a good 7m white line track and test how well the vehicle can run along the track.

Track was marked out in the STEAM discovery centre, as this has black flooring, each tile is 500mm so 14 tiles = 7m (7000mm)

Results were excellent. The dragster has Bluetooth so can send data back to a mobile phone.

Data is sent back to phone.

I was intending to use a potentiometer to control the motor speed, however using an arduino seems rather overkill for this. So I will just do that directly.

I decided to build a car instead, so far this has 2 wheels and just goes forward.

#include <AFMotor.h>

AF_DCMotor motorA(3);
AF_DCMotor motorB(4);

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  //Serial.begin(9600);
  motorA.setSpeed(100);
  motorA.run(RELEASE);
  motorB.setSpeed(100);
  motorB.run(RELEASE);
}

// the loop routine runs over and over again forever:
void loop() {

  
  
//Motor spinning clockwise
  motorA.run(FORWARD);
  //Speed up
  motorA.setSpeed(100);  
  motorB.run(FORWARD);
  //Speed up
  motorB.setSpeed(100); 
    


  }
