ATTINY412 20MHz 4Kb Flash Blink Sketch

/*
Here's some sample code to program the ATTINY412 20MHz 4Kb Flash using the Arduino IDE and the ATtinyCore library:

1. Install the ATtinyCore library in the Arduino IDE by following the instructions in the link below:
https://github.com/SpenceKonde/ATTinyCore

2. Open the Arduino IDE and select "ATtiny412" under the "Tools" > "Board" menu.

3. Select the appropriate programmer under the "Tools" > "Programmer" menu. If you are using an ISP programmer, select "USBasp" or "AVRISP mkII" from the list. If you are using an Arduino board as a programmer, select "Arduino as ISP" from the list.

4. Connect your programmer to the ATTINY412 according to the pinout diagram.

5. Upload the code to the ATTINY412 by clicking the "Upload" button in the Arduino IDE.

6. Verify that the LED is blinking at a 1-second interval.

This code provides a basic framework for programming the ATTINY412 using the Arduino IDE and the ATtinyCore library. You can modify the code to suit your specific requirements, such as changing the pin number or the delay time.

Use the following sample code to blink an LED connected to pin PB0:
*/

// define the LED pin
const int LED_PIN = PB0;

void setup() {
  // set the LED pin as an output
  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  // turn the LED on
  digitalWrite(LED_PIN, HIGH);
  delay(500);

  // turn the LED off
  digitalWrite(LED_PIN, LOW);
  delay(500);
}
