Two ready-to-upload Arduino sketches for finding the addresses of I2C devices on your bus. Stop guessing addresses and stop digging through datasheets — scan the bus directly and get the answer in ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

Our lunabot uses paired linear actuators (left/right lift, left/right tilt) driven by REV SparkMax controllers over CAN bus. During excavation and depositing, the actuators drift out of sync, causing ...
