/* Blink (modified slightly for ATTiny84/44 ICs Turns on an LED on for one second, then off for one second, repeatedly. This example code is in the public domain. */ // ATTIny84 / 44 does not have Pin 13, so we use pin 7 instead. // A current limiting resistor should be connected in line with the LED. int led = 7; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); } // the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(100); // wait for a second digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(100); // wait for a second }
