Regards to all
can someone help me to make circuit with lm317 and transistor led police lights
i plan to use 1w led 350ma
i have code here
void setup() {
// initialize the digital pin as an output.
pinMode(13, OUTPUT);
pinMode(12, OUTPUT);
pinMode(11, OUTPUT);
pinMode(10, OUTPUT);
pinMode(9, OUTPUT);
pinMode(8, OUTPUT);
pinMode(7, OUTPUT);
pinMode(6, OUTPUT);
}
void loop() {
digitalWrite(13, HIGH);
digitalWrite(12, HIGH);
digitalWrite(11, HIGH);
digitalWrite(10, HIGH);
delay(50);
digitalWrite(13, LOW);
digitalWrite(12, LOW);
digitalWrite(11, LOW);
digitalWrite(10, LOW);
delay(50);
digitalWrite(13, HIGH);
digitalWrite(12, HIGH);
digitalWrite(11, HIGH);
digitalWrite(10, HIGH);
delay(50);
digitalWrite(13, LOW);
digitalWrite(12, LOW);
digitalWrite(11, LOW);
digitalWrite(10, LOW);
delay(50);
digitalWrite(13, HIGH);
digitalWrite(12, HIGH);
digitalWrite(11, HIGH);
digitalWrite(10, HIGH);
delay(50);
digitalWrite(13, LOW);
digitalWrite(12, LOW);
digitalWrite(11, LOW);
digitalWrite(10, LOW);
delay(50);
digitalWrite(9, HIGH);
digitalWrite(8, HIGH);
digitalWrite(7, HIGH);
digitalWrite(6, HIGH);
delay(50);
digitalWrite(9, LOW);
digitalWrite(8, LOW);
digitalWrite(7, LOW);
digitalWrite(6, LOW);
delay(50);
digitalWrite(9, HIGH);
digitalWrite(8, HIGH);
digitalWrite(7, HIGH);
digitalWrite(6, HIGH);
delay(50);
digitalWrite(9, LOW);
digitalWrite(8, LOW);
digitalWrite(7, LOW);
digitalWrite(6, LOW);
delay(50);
digitalWrite(9, HIGH);
digitalWrite(8, HIGH);
digitalWrite(7, HIGH);
digitalWrite(6, HIGH);
delay(50);
digitalWrite(9, LOW);
digitalWrite(8, LOW);
digitalWrite(7, LOW);
digitalWrite(6, LOW);
delay(50)
}
Thanks in advance
