Introduction

Source code for the geek spinner board from the Hackafe geek spinner workshop.

Prerequisites

• Install ATTiny Core Support
• Install EEPROMex Library

Preparing for uploading

• Pick up a spare Arduino UNO from your desk
• Program it with the Arduino ISP sketch from the IDE menu File->Examples->ArduinoISP->ArduinoISP

Compiling and Uploading

Compiling

• Download ZIP archive or clone this repository.
• Open the SMD_spinner.ino file
• From the arduino IDE select the tools menu Tools->Board and scroll down and find ATtiny 24/44/84
• Then again click on Tools menu and select ATtiny84 from the Chip option
• Click on Tools and then select Clockwise from the Pin mapping option
• Select the oscillator speed 8Mhz Internal from Tools->Clock
• Click on Verify to verify that the sketch compiles without errors

Uploading

• Pick up the Arduino UNO you programmed earlier and wire it with the ATtiny84 chip from the spinner from this diagram

• From Tools->Programmer select Arduino as ISP

• From Tools->Port select the port of the Arduino UNO connected to your PC

• Hit the upload button from the Arduino IDE. The upload process to the ATtiny84 should take 10 seconds.

Changing

• You can change the text and shapes of your spinner from the textAndShapes.h header file

Notes

• You can use any Arduino board to program the ATtiny84, just google for Arduino [UNO/MEGA] etc.. as a programmer
