All Services Programming & Development Programming & Software Arduino $20/hr · Starting at $100 I have done several projects with different Arduino (UNO, Leonardo, Yun, ...), interacting with power relays, database and so. The goal is most of the time to let sensors interact with IT systems in different forms like: Arduino/MCU -> Linux system (from Raspberry Pi up to Linux Servers) for example a database reaches a certain condition (SELECT statement) when that comes true an Arduino/MCU sets certain an output high which triggers a relay coil and an electric device is switched on. On the other hand a temperature read from an Arduino/MCU is read that can be transferred to a database (MSSQL, MySQL, PostgreSQL, ...), with a timestamp and other needed attributes.
