This project uses a Raspberry Pi 2 or 3, an Arduino Uno, some servos, and a USB webcam. The end result is a camera mounted to the servo that’s controlled by the Arduino.

The basic functions of the Arduino IDE – pinMode, digitalRead, digitalWrite, and analogRead – are available. Most of the WiFi functions work just like the WiFi shield library.

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 … ...
