Hey there, I recently got myself an arduino uno for embedded programming, but it lacks the amount of IO pins the EZ-B has, then I thought to myself, why not control the ezb from the arduino? So here, I've ported a minimal part of Openbot to arduino to control servos and set digital ports for now. To make this work you connect the pin 5 in your arduino to the rx pin in the EZB with a jumper cable and pin 6 in your arduino to the tx pin in EZB and voila. I've made a quick example here that uses 2 servos and turns on some leds. Be aware that the class itself does not require the Arduino Timer library, but my sketch does, so here it is.

Tell me what you think

#include toneAC.h

#define SERVO_CENTER 70
#define SERVO_MAX 40
#define SERVO_MIN 1
#define SERVO_OFF 0
#define SERVO_SPEED_FASTEST 0
#define SERVO_SPEED_SLOWEST 10

#include Event.h
#include Timer.h

  EzRobotConnection.write(85);
}


  EzRobot::EzRobot(){

  EzRobot::EzRobot(byte rx, byte tx) {
    Serial.println("LODS");
    EzRobotConnection = SoftwareSerial(rx,tx);
