If you have read my blog for a bit, you will know that I love NeoPixels and I love hacking with them. So when I learnt about Nexmo, a service that offers SMS and voice telephony over the web, I wondered how I could use it with my favourite hack.
The project uses the Nexmo API and Node-RED to read an incoming SMS and extract either the name of a predetermined color, or an RGB color value. This is then passed to a node which will control the NeoPixels.
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.
