Jaime Lightfoot has written an excellent ‘beginner’s tutorial‘ for XBee using an Arduino Uno – you are free to adapt the guide to your board of choice. The project uses a few basic components like resistors, momentary button, LED, and the necessary modules and software to make it all happen. This is a great starter project for XBee!
This blog post will cover the steps (and some background knowledge) needed for a basic XBee setup. The goal is to get two XBee modules to communicate. We’ll have a basic input (a button) on one side, which will remotely trigger an output (an LED) on the other side. This models the basic functionality of the overall Callaloo system: proximity sensors on the door (input) are transmitted to a receiving module that changes an output (indicator lights, server information) based on the data it receives.
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.
