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.

Furthermore, it can be controlled using the I2C ... is a test sketch for the initial tryout. This lucid sketch shows how to select the receiver frequency (setBandFrequency), set the volume (setVolume) ...

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.

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.
