I must apologize; that description for how to upload the firmware was utterly terrible; it was more applicable to the v1 firmware than to the current process. I’ve updated it to say rather explicitly what you need to do. First, install the Alpha Clock Five library for Arduino, and then open up the example file from the menu to upload it.
Please give that a try, according to the newly updated instructions, and let me know if you have any additional trouble.
