ESP32 PCB and Alexa
ELECTRONOOBS Jun 04,2023
Today we learn how to control stuff using Alexa and an ESP32 and make it work with this PCB. We can control anything. Check example in the video below. And this works in any language, just change Alexa settings to your language and when you add the device, in the Arduino code, just write the name in that language. For example, it could work in Spanish if you want. This project works perfectly with my Noobix board from a previous project and this already has the ESP32, the programming pads, 12V a…

ESP32 RYLR993 LoRaWAN Communication
Useful Electronics Jun 02,2023
In this tutorial, I have built a simple system that is powered with 1 W 5 V solar panel that monitors the connected battery voltage with ADC and gets the environment temperature and shares this information with the thing network over LoRaWAN. The system also supports modifying GPIO state wirelessly over LoRaWAN. The system uses RYLR993 LoRaWAN Module and ESP32C2 as hosting MCU. The LoRaWAN module is controlled using AT commands over UART and contains an internal temperature sensor that the syste…

Stereo I2S Shield – The next iteration…Last month I started working on a Stereo I2S Audio shield for my ESP32-S development board. Those of you that saw that post will remember that I made some mistakes on the initial prototype, and had to repair it with a few “greenwire” connections.The prototype shield also required the use of commercial I2S modules to be plugged into it, making for quite a cumbersome first iteration.Stereo I2S shield stacked onto esp32-S dev boardI decided to do something…

ESP32C2 TCA6416A IO Expansion Driving 7-Segment Display
Useful Electronics May 24,2023
In this tutorial, ESP32C2 is used to interface 2 digits 7 segments display using TCA6416A pin expander that communicates over I2C. TCA6416A has 16 input and output pin interface capability. In this simple project every single pin is connected to an LED to represent a segment. 3D printed LED defuser is used to make the number representation more meaningful.GitHub Repository:https://github.com/UsefulElectronics/esp32c2-tca6416a-i2c-pin-expander

ESP32 Dev Breakout Board
Reboot May 22,2023
This is a breakout board for the 30 pin DOIT ESP32 DEVKIT V1 module.There are 30 header pins for easy hook up to the module since the module on its own is awkward to fit on a breadboard.There's also some convenient peripherals for quick prototyping including:4 LEDs4 buttons4 pcb copper touch pads4 bi-directional 3.3v to 5v FET level shifters2 op amp circuitsThe components aren't directly wired to the ESP32, there are headers so they can be jumpered with Dupont wires as needed, leaving the module…
