You'll need your microcontroller, a temperature sensor, and a button—we're going to build a bot that sends a text message with the inside and outside temperature data when you press the button. If you can get your hands on a Particle Photon (check out the shop at www.particle.io), you'll also learn how to make your code work on both platforms without changing more than two lines!
Finally, you'll need your enthusiasm and curiosity—these are the things that'll give you ideas for your next NodeBots project!
