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 ...

With a title like Hardware Hacking 101: E01 I2C Sniffing, How to Listen to Your Arduino’s I2C Bus, you know you’re in for a good time.

Actually, PCF8574 and PCF8574A are identical, except for the different fixed portion of the slave address. The three hardware address pins allow eight of each device to be on the same I 2 C-bus, so ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Who Won and Lost in Trump’s Tax Bill Scientists tracking ‘interstellar’ object that has come ...

The Arduino has analogue inputs and hardware blocks including I2C and timers. “Using a hardware I2C device means more reliable operation as the software is no longer having to poll the I/O and the ...

Arduino has two new boards out which deliver connectivity - the Arduino MKR WAN 1300 (LoRa) and the Arduino MKR GSM 1400.
