A simple music player is constructed utilizing a JQ6500 MP3 module connected to an ESP32 via serial communication. MicroPython Programming with ESP8266 - PWM - Pulse Width Modulation Issue Q&A Forum › Category: ESP8266 › MicroPython Programming with ESP8266 - PWM - Pulse Width Modulation Issue 0 Vote Up Vote Down. On a previous tutorial, we explored how to control a Raspberry Pi using Jupyter Notebook: R P I P h y s i c a l C o m p u t i n g U s i n g J u p y t e r N o t e b o o k It was a great experience, and once the project worked very well I thought, "how about I also test the Jupyter Notebook on an ESP8266 (or even on ESP32) using MicroPython?". As ESP32 Arduino core lacks analogWrite() function, we achieve PWM using following functions : ledcAttachPin() ledcSetup() ledcWrite() Pulse. In short, it's a small form factor and fairly high cost effective wireless module. Specifically wondering about susceptibility to static electricity, as we have had static electricity problems before with our robots.
