i need some assistance on this …
// Move Motor A Forward and Backwards x axis
//Move Motor B (actuator) UP/DOWN y Axis
// Motor A
int enA = 10;
int in1 = 8;
int in2 = 7;
// Joystick Input
int joyVert = A2; // Vertical
int joyHorz = A1; // Horizontal
// Motor Speed Values - Start at zero
int MotorSpeed1 = 0;
// Joystick Values - Start at 512 (middle position)
int joyposVert = 512;
int joyposHorz = 512;
void setup()
{
// Set all the motor control pins to outputs
pinMode(enA, OUTPUT);
pinMode(in1, OUTPUT);
pinMode(in2, OUTPUT);
// Start with motors disabled and direction forward
// Motor A
digitalWrite(enA, LOW);
digitalWrite(in1, HIGH);
digitalWrite(in2, LOW);
}
void loop() {
// Read the Joystick X and Y positions
joyposVert = analogRead(joyVert);
joyposHorz = analogRead(joyHorz);
// Determine if this is a forward or backward motion
// Do this by reading the Verticle Value
// Apply results to MotorSpeed and to Direction
if (joyposVert > 564)
{
// This is Forward
// Set Motor A forward
digitalWrite(in1, HIGH);
digitalWrite(in2, LOW);
// Set Motor B forward
//Determine Motor Speeds
MotorSpeed1 = map(joyposVert, 564, 1023, 0, 255);
}
else if (joyposVert < 460)
{
// This is Backward
// Set Motor A backward
digitalWrite(in2, HIGH);
digitalWrite(in1, LOW );
// Set Motor B backward
//Determine Motor Speeds
// As we are going backwards we need to reverse readings
joyposVert = joyposVert -460;
joyposVert = joyposVert * -1;
MotorSpeed1 = map(joyposVert, 0, 460, 0, 255);
}
// Adjust to prevent “buzzing” at very low speed
// Set the motor speeds
analogWrite(enA, MotorSpeed1);
}
Working on one axis and one motor only right now. my axis moves the motor A forward(right). when moving joystick in opposite direction… no movement. If i change the digitalWrite HIgh, lOW as the Forward to match the Forward comand… it activates the motor in with movement of joystick LEFT/RIGHT but only moving motor in one direction.
I want… to operate one motor LEFT/RIGHT with one potentiometer(joystick axis) using an l298N H bridge.
HEEEELP.
