I am working towards a big project by completing it in smaller parts, at the moment, I'm just making two motors that go forward at a speed set by a potentiometer when a button is being pressed. I'm using the Adafruit motor shield I'm having some problems, these problems are extremely strange, the motor stays on for seemingly random periods of time and the potentiometer doesn't seem to be working. I was looking for troubleshooting but it's also possible that my wiring is bad because the Adafruit motor shield just has holes and wires stay in horribly.
Thanks
Here's my coded
#include <Wire.h>
#include <Adafruit_MotorShield.h>
#include "utility/Adafruit_PWMServoDriver.h"
Adafruit_MotorShield AFMS = Adafruit_MotorShield();
Adafruit_DCMotor *leftMotor = AFMS.getMotor(1);
Adafruit_DCMotor *rightMotor = AFMS.getMotor(2);
int potPin = 2; // select the input pin for the potentiometer
int val = 0; // variable to store the value coming from the sensor
const int BUTTON = 5; //corresponds to button used to toggle motor
const int BUTTON2 = 12; //corresponds to button used to toggle servo
void setup()
{
Serial.begin(9600);
Serial.println("Adafruit Motorshield v2 - DC Motor test!");
AFMS.begin();
pinMode(BUTTON, INPUT);
}
void loop()
{
val = analogRead(potPin);
bool pressingButton = (digitalRead(BUTTON) == HIGH) ? true : false;
if(pressingButton == true)
{
leftMotor->setSpeed(val); //set the speed
leftMotor->run(FORWARD); //set the run direction
rightMotor->setSpeed(val); //set the speed
rightMotor->run(FORWARD); //set the run direction
//leftMotor->run(RELEASE); //turn on motor
}
else
{
leftMotor->run(RELEASE);
rightMotor->run(RELEASE);
}
}
By "holes", do you mean the through-plated solder pads that are designed to solder pins to? Or do you mean pin sockets? Can you be more specific, or post a photo?

Here's a picture, it's not mine, those holes just below/above the soldered ones are what I'm referring to, I'm not sure of the technical term
Did you try soldering to them? Only the Female Headers are meant to hold wires without soldering, and even those work best with crimp terminals on the wires.
Crimp on your own
and slide into housing for separation, singly or in groups (groups are more secure) https://www.pololu.com/product/1900
Or use terminated wires. Can buy them long, and cut in half to connect to your stuff
Here's an updated version I've made a couple of modifications
#include <Wire.h>
#include <Adafruit_MotorShield.h>
#include "utility/Adafruit_PWMServoDriver.h"
Adafruit_MotorShield AFMS = Adafruit_MotorShield();
Adafruit_DCMotor *leftMotor = AFMS.getMotor(1);
Adafruit_DCMotor *rightMotor = AFMS.getMotor(2);
int potPin = 2; // select the input pin for the potentiometer
int val = 0; // variable to store the value coming from the sensor
const int BUTTON = 5; //corresponds to button used to toggle motor
const int BUTTON2 = 12; //corresponds to button used to toggle servo
void setup()
{
Serial.begin(9600);
Serial.println("Adafruit Motorshield v2 - DC Motor test!");
AFMS.begin();
pinMode(BUTTON, INPUT);
}
void loop()
{
val = analogRead(potPin);
bool pressingButton = (digitalRead(BUTTON) == HIGH) ? true : false;
if(pressingButton == true)
{
leftMotor->setSpeed(val / 4); //set the speed
leftMotor->run(FORWARD); //set the run direction
rightMotor->setSpeed(val / 4); //set the speed
rightMotor->run(FORWARD); //set the run direction
//leftMotor->run(RELEASE); //turn on motor
}
else
{
leftMotor->run(RELEASE);
rightMotor->run(RELEASE);
}
}
