Topic: roaming tank (Read 1 time) previous topic - next topic


OK so i am kind of new to this ,
so far i have constructed the tank in the pic below
Audrino mega
motor shield (added heat sync)
4 ping (parallax)
2 motors (3V i think)

I looked over several sketches for Wandering with ping but still confused on how to modify for current hardware


What needs to be modified?


I can  get it  to  spit out  ranges  from the sensors
however i  am unsure of how to  get  it  to  change directions based on ranges
or is it that i should us  IF statements?

"if" statements are the easiest way.  Take a look at a sketch that I did with Ping sensor and servos.

I also recommend the "NewPing" library.

Code: [Select]
#include <Servo.h>

#define trigPin 8
#define echoPin 9
Servo righteyelid;
Servo lefteyelid;
int pos = 0;

void setup() {
 Serial.begin (9600);

void loop() {
 int duration, distance;
 digitalWrite(trigPin, HIGH);
 digitalWrite(trigPin, LOW);
 duration = pulseIn(echoPin, HIGH);
 distance = (duration/2) / 29.1;
 if (distance <= 10)
   Serial.println("servo on");
 else {
   Serial.println(" cm");
