Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language and the Arduino Software (IDE).

Raspberry Pi has introduced a successor to last year’s Pico, a $4 microcontroller based on the RP2040 chip the company designed itself. The new model is called the Pico W. It’s basically the same hardware, but it adds, as the name suggests, an 802.11n Wi-Fi radio, making it useful for putting together IoT projects and the like. It’s also more expensive than the standard Pico, coming in at $6.
