The ESP32 is an inexpensive yet super-powerful 32-bit microcontroller that is loaded with advanced features, including WiFi and Bluetooth BLE.
Espressif released the ESP32 in September 2016. This was an upgrade to the ESP8266, adding more I/O ports, memory, processing power, and features. Along with the ESP32 release, Espressif also provided extensive, multilingual documentation, updated development tools, and a board manager for the ...

Today we will be putting together a robot car based upon the popular ESP32CAM module. Our car will have a WiFi remote control and will stream video, so you can see where you are going when you drive it! Read More » Build a Developers Linux Workstation ...

Today, we will interface a PS3 controller to an ESP32. Our work will be simplified by using a great library that does pretty well everything for us. Even if you don’t own a PlayStation 3 (I don’t), you can buy a PS3 controller “clone” for next to nothing. The model I pur...
Since both modules have a pair of QWIIC connectors, I used both and a SparkFun ESP32C6 module for a quick test (no pun intended there!). I connected both modules to the ESP32C6 module with QWIIC cables. I wired each module’s potentiometer as a voltage divider withRHgoing toVCCandRLgr...

The Raspberry Pi 3 and Raspberry Pi 4 both have a 3.5mm audio jack, so they can be used right out of the box. As a matter of fact, so can the older Raspberry Pi 2, if you still have one around. You can also use a Raspberry Pi Zero, however, you’ll need to attach a Digital...
Connect a signal generator or low-level audio source to the inputs of our basic design. Make sure to only have this connected while the Pico is powered by the Android phone or tablet, otherwise, the ground resistor will likely get shorted out. ...
