Programming Arduino with photogate firmware¶
Note: If you received a pre-programmed Arduino with your photogate kit you can skip this section.
To build the photogate firmware you will also need the Arduino Streaming library [1].
- Download the Arduino photogate firmware from https://bitbucket.org/iorodeo/photogate_software/get/default.zip
- Unzip the .zip archive. The firmware is located in the firmware subfolder
- Connect your Arduino board. Launch the Arduino IDE [2] and open the main firmware file “firmware.ino”
- Select the Arduino Uno board model
- Select the serial port it is using – under “Tools” menu of the Arduino IDE
- Upload the photogate firmware to the Arduino board.
