A small project In this small project, we want to read the analogue sensor (slider) and display the result on the rgb LED ring. To do this, we will divide the possible...
The rgb LED chain The LED employed on the LoLin RGB LED card is very different from the one we used on the CPU card. In fact, the card uses cascadable, addressable...
Analogue Signals Up to now, we only treated digital signals in output mode (LED) and in input mode (pushbutton). Sensors often produce analogue signal levels, however...
Hardware access, the General Purpose Input Output (GPIO) pins. Running the programs on the PC Up to now, all programs we have written can be executed on the ESP...
Python modules and timing Python libraries are arranged as modules, containing a number of functions and/or classes. These modules must be imported before being...
First Python programs Introduction It is not possible to go through Python programming in just an hour. We will therefore learn only those features that are absolutely...
