Step 1: Setting Up the Arduino IDE:

1. Download and install the latest version of the Arduino IDE from the official Arduino website.
2. Launch the Arduino IDE and go to “File” > “Preferences.”
3. In the “Additional Boards Manager URLs” field, add the following URL: http://drazzy.com/package_drazzy.com_index.json
4. Click “OK” to save the preferences.

Step 2: Installing ATtiny85 Support:

1. Navigate to “Tools” > “Board” > “Boards Manager.”
2. In the search bar, type “ATTinyCore” and install the ATtinyCore by Spence Konde.
3. Once installation is complete, select “ATtiny25/45/85 (No bootloader)” from the “Tools” > “Board” menu.

Step 3: Wiring the ATtiny85:

1. Connect your USBasp programmer to the ATtiny85 following the appropriate pinout.
2. Place the ATtiny85 on a breadboard and make the necessary connections using jumper wires. For example, connect an LED to Pin 5 (PB0) with a current-limiting resistor.

Step 4: Writing and Uploading Your First Program:

1. Go to “File” > “Examples” > “01.Basics” > “Blink” to open the Blink example.
2. Modify the code to specify Pin 5 (PB0) as the LED pin.
3. Click the “Upload” button to compile and upload the program to the ATtiny85.

Step 5: Verifying the Output:

1. Once the program is uploaded successfully, the LED connected to Pin 5 (PB0) should start blinking.
2. Congratulations! You’ve successfully programmed the ATtiny85 to control an LED.

To utilize the Tech Fun Zone Mini Programming Shield effectively, you’ll require an Arduino board running the ArduinoISP sketch. This specific Arduino board acts as the programmer, and you need to upload the “Arduino as ISP” sketch onto it. By doing so, you enable the Arduino to program or burn the bootloader onto another Arduino or other AVR microcontrollers.

Here’s a step-by-step guide to loading the ArduinoISP sketch onto your programmer Arduino:

**Step 1: Set up the Arduino IDE**

Ensure that you have the Arduino IDE installed on your computer. If not, you can download it from the official Arduino website: https://www.arduino.cc/en/software

**Step 2: Connect the Arduino boards**

Connect your “programmer” Arduino board (the one used to program ATtiny chip) to your computer via a USB cable. Plug the Tech Fun Zone Mini Programming Shield into the designated pins of the programmer Arduino.

**Step 3: Select the Board and Port**

1. Open the Arduino IDE on your computer.

2. Select the board that corresponds to your programmer Arduino (e.g., Arduino Uno) from the “Tools” > “Board” menu.

3. Choose the appropriate serial port for your programmer Arduino from the “Tools” > “Port” menu.

**Step 4: Load the ArduinoISP sketch**

1. In the Arduino IDE, go to “File” > “Examples” > “11.ArduinoISP” and click on “ArduinoISP” to open the sketch.

2. Verify that the board and port settings are correct by going to “Tools” > “Board” and “Tools” > “Port.”

3. Click on the “Upload” button (right arrow icon) to load the ArduinoISP sketch onto your programmer Arduino.

If everything goes well, the ArduinoISP sketch should now be loaded onto your programmer Arduino through the Tech Fun Zone Mini Programming Shield. You can disconnect the connections between the two Arduinos and use the target Arduino as a standalone device or continue using the programmer Arduino to burn bootloaders or program other compatible AVR microcontrollers.

With the above steps completed, the Tech Fun Zone Mini Programming Shield offers a hassle-free solution to program an ATTINY84A chip without any additional wiring to the Arduino. The shield seamlessly plugs directly into the Arduino board, streamlining the process for ease and convenience. Here’s a simple step-by-step guide on how to achieve it:

1. Insert the Tech Fun Zone Mini Programming Shield into the Arduino board.
2. Place the ATTINY chip into the socket on the Tech Fun Zone Mini Programming Shield.
3. Connect the Arduino board to your computer via a USB cable.
4. Keep the connection between the programmer Arduino (the one with the Tech Fun Zone Mini Programming Shield) and the shield itself intact.
5. Set up the programming parameters: a. In the Arduino IDE, go to “Tools” > “Board” and select the appropriate ATTINY chip type (e.g., ATtiny 24/44/84) from the “ATTINY” section. b. Choose “Arduino as ISP” from the “Tools” > “Programmer” menu.
6. To burn the bootloader or program the ATTINY chip, click on “Tools” > “Burn Bootloader.”

With these steps, you have successfully connected the Tech Fun Zone Mini Programming Shield to the Arduino and prepared it to program the ATTINY chip. Now, you can proceed to burn the bootloader or upload your code to the ATTINY chip for your project’s specific functionality.
