Sample Program Program I: //You can "manually" implement PWM on any pin by repeatedly turning the pin on and off for the desired times. void setup() { pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); delayMicroseconds(100); // Approximately 10% duty cycle @ IKHz digitalWrite(13, LOW); delay Microseconds(1000 - 100); } Program 2: //PWM program by using the PWM pin int LED_pin = II; int level1 20; int level2 = 200; void setup() { pinMode(LED_pin, OUTPUT); } void loop() { analogWrite(LED_pin, levell); delay(1000); analogWrite(LED_pin, level2); delay(1000); } Read the description and methodology mentioned above. Try to understand it and run the code. Write the output in the box below.
