The development of the Arduino ATMEGA2560 Skyboard and its associated labs was inspired by the ENGR383 Embedded Systems course in the Electrical Engineering department at the Colorado School of Mines. The original labs were created using the PIC MCU by Dr. Chris Coulston and his colleagues. I adjuncted there in Fall 2024 during my sabbatical and decided to re-develop the labs using the Arduino ATMEGA2560 MCU. Undergraduate student Kaifeng Liu developed the Skyboard v2 and most of the code during summer 2025 under an internship sponsored by NSF STROBE.
