for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. However, if you use an LCD module with I2C interface, you only need 2 lines to process the display information. Now a days, ...

In turn, his movements are recreated on the LCD. Pretty mean feat, if you ask us. If you'd like to marvel at his code -- or even try it out for yourself -- hit up the source link.

and making the familiar Arduino commands work with the ESP32’s peripheral hardware is the job of the core firmware. As of this writing, GPIO, WiFi, SPI and I2C were ready to test out.

Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will record what is going on for a set time interval, then dump the data via serial as a .csv.

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
