Thanks for your help Tim, I have now attached the sensor to D3 and I am able to get readings via serial. Could you or anybody else help me change this code to work with your library:
#include <ArduinoRobot.h>
#include <Wire.h>
#include <SPI.h>
int sensorPin = M1; // pin is used by the sensor
void setup() {
// initialize the Robot, SD card, and display
Serial.begin(9600);
Robot.begin();
Robot.beginTFT();
Robot.beginSD();
Robot.displayLogos();
// draw a face on the LCD screen
setFace(true);
}
void loop() {
// If the robot is blocked, turn until free
while (getDistance() < 40) { // If an obstacle is less than 20cm away
setFace(false); //shows an unhappy face
Robot.motorsStop(); // stop the motors
delay(1000); // wait for a moment
Robot.turn(90); // turn to the right and try again
setFace(true); // happy face
}
// if there are no objects in the way, keep moving
Robot.motorsWrite(255, 255);
delay(100);
}
// return the distance in cm
float getDistance() {
// read the value from the sensor
int sensorValue = Robot.analogRead(sensorPin);
//Convert the sensor input to cm.
float distance_cm = sensorValue * 1.27;
return distance_cm;
}
// make a happy or sad face
void setFace(boolean onOff) {
if (onOff) {
// if true show a happy face
Robot.background(0, 0, 255);
Robot.setCursor(44, 60);
Robot.stroke(0, 255, 0);
Robot.setTextSize(4);
Robot.print(":)");
} else {
// if false show an upset face
Robot.background(255, 0, 0);
Robot.setCursor(44, 60);
Robot.stroke(0, 255, 0);
Robot.setTextSize(4);
Robot.print("X(");
}
}
This is meant to be used with an analog sensor like a Maxbotix EZ10.
Thanks for your help so far!
Jay.
P.S. All of the LCD stuff isn't important, it is just the sensor working with the motors I need working. Thanks again!
