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 ...

It’s not much of a stretch to assume that the majority of Hackaday readers are at least familiar with I2C. In fact, there’s an excellent chance that anyone who’s ever done more with an Arduino than ...

A while ago I received a couple of I/O port expander modules that use the I 2 C protocol. Using that Chinese module, you can use only the SDA and SCL pins of your Arduino, or any microcontroller ...

Arduino has two new boards out which deliver connectivity – the Arduino MKR WAN 1300 (LoRa) and the Arduino MKR GSM 1400. The Arduino MKR WAN 1300 delivers LoRa low-power WAN connectivity, and the ...
