1/*2Blink without Delay34Turns on and off a light emitting diode (LED) connected to a digital pin,5without using the delay() function. This means that other code can run at the6same time without being interrupted by the LED code.78The circuit:9- Use the onboard LED.10- Note: Most ...
}voidloop() {//here is where you'd put code that needs to be running all the time.//check to see if it's time to blink the LED; that is, if the//difference between the current time and last time you blinked//the LED is bigger than the interval at which you want to//blink ...

LED Blink Note, onboard LED is inverted - LOW turns it on! Onboard LED is connected to GPIO2 void setup() { // initialize digital pin LED_BUILTIN as an output. #define LED_BUILTIN 2 pinMode(LED_BUILTIN, OUTPUT); } // the loop function runs over and over again forever void loop...
NOTE: The internal pull-up resistor (turned on by calling digitalWrite(0) after setting the pin to output, where 0 is the pin number) are much weaker (about 25 kohm) on an ATtiny than on an Arduino, so the onboard LED interferes with them. If you need them, you can use a differe...

This sketch receives a digit (single characters 0 through 9) and blinks the onboard LED at a rate proportional to the received digit value: /* * SerialReceive sketch * Blink the LED at a rate proportional to the received digit value */ int blinkDelay = 0; // blink delay stored in th...

(about 25 kohm) on an ATtiny than on an Arduino, so the onboard LED interferes with them. If you need them, you can use a different port. Change your circuit to not need the internal pull-up, or cut the LED trace. For Model A this would apply to P1 for Model B this would ...
