arduino ln298n control speed one dc motor code example
Example: arduino l298n code
//Pin Out
const int IN1 = 7;
const int IN2 = 6;
const int IN3 = 5;
const int IN4 = 4;
const int ENA = 9; //pin for speed control en1
const int ENB = 3; //pin for speed control en2
void setup() {
pinMode (IN1, OUTPUT);
pinMode (IN2, OUTPUT);
pinMode (IN3, OUTPUT);
pinMode (IN4, OUTPUT);
pinMode (ENA, OUTPUT);
pinMode (ENB, OUTPUT);
}
void loop() {
//control speed
//(pin, speed)
analogWrite(ENA, 255);
analogWrite(ENB, 255);
//control direction
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);
digitalWrite(IN3, HIGH);
digitalWrite(IN4, LOW);
