Random Code

• Writing an arbitrary number of bits to pins

  byte pins[] = {2,3,4,5,6,7};
  byte totalPins = 6;
  
  void setup(){
     for(byte a = 0; a < totalPins; a++){
        pinMode(pins[a], OUTPUT);
     }
  }
  
  void writeData(byte data, byte numberOfBits, byte startBit){
     for(byte a = startBit; a < numberOfBits; a++){
        if((data >> a) & 0x01){
           digitalWrite(pins[a], HIGH);
        }else{
           digitalWrite(pins[a], LOW);
        }
     }
  }

Scooter Code

• The following code is for controlling the scooter wirelessly.

  struct data {
     byte start;
     byte left;
     byte right;
     byte finish;
  };

  typedef struct data Packet;

  Packet myData =  {0, 0x55, 0x7e, 0};
