Introduction: V1 Rotary Encoder Using Attiny Microcontroller

By

i made a rotary encoder generator using attiny microcontroller which can be used for simulation in proteus and tinkercad as there no encoder wheel viable in them

Step 2: Source Code

at here you can there is a simple code given for the attiny

// C++ code

//

void setup()

{

 pinMode(4, INPUT);

 pinMode(3, INPUT);

 pinMode(0, OUTPUT);

 pinMode(1, OUTPUT);

 pinMode(2, OUTPUT);

 pinMode(5, INPUT);

}


void loop()

{

 if (digitalRead(4) == HIGH) {

  if (digitalRead(3) == HIGH) {

   digitalWrite(0, HIGH);

   digitalWrite(1, LOW);

   digitalWrite(2, LOW);

   delay(100); // Wait for 100 millisecond(s)

   digitalWrite(0, HIGH);

   digitalWrite(1, HIGH);

   digitalWrite(2, LOW);

   delay(100); // Wait for 100 millisecond(s)

   digitalWrite(0, LOW);

   digitalWrite(1, HIGH);

   digitalWrite(2, HIGH);

   delay(100); // Wait for 100 millisecond(s)

   digitalWrite(0, LOW);

   digitalWrite(0, LOW);

   digitalWrite(0, HIGH);

   delay(100); // Wait for 100 millisecond(s)

  }

  if (digitalRead(5) == HIGH) {

   digitalWrite(0, LOW);

   digitalWrite(1, LOW);

   digitalWrite(2, HIGH);

   delay(100); // Wait for 100 millisecond(s)

   digitalWrite(0, LOW);

   digitalWrite(0, LOW);

   delay(100); // Wait for 100 millisecond(s)

  }

 } else {

  if (digitalRead(3) == HIGH) {

   digitalWrite(0, LOW);

   digitalWrite(1, LOW);

   digitalWrite(2, LOW);

   delay(100); // Wait for 100 millisecond(s)

   delay(100); // Wait for 100 millisecond(s)

  }
