Everything with a microcontroller has serial buses in it. Busses like UART, I2C, and SPI are very popular choices. When you have a problem with a sensor that uses one or the bus itself, you can use an oscilloscope or logic analyzer to “decode” the traffic. These decoders convert the 1s and 0s into readable HEX or ASCII characters.
I am not sure how I thought of the “multiple” James idea for the thumbnail. The concept had something to do with “serial,” but I am not sure what.
Anyway, my favorite James is the far left one. He has no idea where the camera is at.
Oh and this picture was done without a green screen. I took multiple shots of me standing in different spots and then composited them together.
