Making custom applications for Android OS can be difficult unless you have a deep understanding of Java. MIT’s App Inventor removes that barrier by providing an easy to use drag and drop style of coding to App development.
This guide will take you through the steps to create a dedicated app for your IoT project using any of the Particle devices. It will focus on the simple Web Connected LED sketch from Particle, then point out the critical parts of the App Inventor code that will let you send and receive any information to and from the Particle device.

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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
