This project provides a simple and practical solution using an Interactive Voice Response System (IVRS) that works completely ...
In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...
The circuit diagram of this system represents the interconnection between the ESP32-CAM, OLED display, and rotary encoder.
Write and test first, then buy the hardware you need.
Based on an ESP32 (using the Arduino stack) and SDCard for control, and a LiPo cell charged wirelessly, the build is rather tidy. A couple of hall effect switches are mounted at the start of each of ...
