ATtiny 85 Programmable Shield for Arduino Uno R3 Made by Jandre Snijman 16 June 2024
// Define the pin where the LED is connected
#define LED_PIN 0
void setup() {
// Set the LED pin as an output
pinMode(LED_PIN, OUTPUT);
}
void loop() {
// Turn the LED on (HIGH is the voltage level)
digitalWrite(LED_PIN, HIGH);
// Wait for a second
delay(1000);
// Turn the LED off by making the voltage LOW
digitalWrite(LED_PIN, LOW);
// Wait for a second
delay(1000);
}
Explanation:
- Define LED_PIN: We define the pin where the LED is connected, in this case, pin 0.
- Setup: In the
setup() function, we set the LED pin as an output.
- Loop: In the
loop() function, we turn the LED on, wait for one second, turn it off, and wait for another second. This cycle repeats indefinitely.
Uploading Code to ATtiny85:
To upload the code to your ATtiny85, follow these steps:
-
Install ATtiny Board Package:
- Open the Arduino IDE.
- Go to
File > Preferences.
- In the
Additional Boards Manager URLs field, add this URL: https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json.
- Click
OK.
-
Select ATtiny85 Board:
- Go to
Tools > Board > Boards Manager.
- Search for "attiny" and install the
attiny by David A. Mellis package.
- Select
ATtiny25/45/85 from the Tools > Board menu.
- Choose
ATtiny85 under Tools > Processor.
- Select
8 MHz (internal) under Tools > Clock.
-
Programmer:
- Select
Arduino as ISP under Tools > Programmer.
-
Upload the Code:
- Connect your ATtiny85 to your computer via an ISP programmer or an Arduino used as ISP.
- Go to
Tools > Burn Bootloader to set the fuses.
- Upload the code by clicking on the
Upload button.
This setup should get your LED blinking on pin 0 of your ATtiny85.
