As a continuation to my Raspberry Pi and Arduino communication post, I thought I’d do the same but opposite way. This time, I thought it would be nice to make a proper Arduino library to make the process more streamlined.
To make communication more robust, I decided to implement a more formal communication over serial to enable applications that have some idea if a command sent to Arduino was successfully carried out or not, and also introduce basic error recovery if invalid commands or wrong number of parameters are received.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
