Getting started with the Particle Photon

I love using all flavors of Arduino in the engineering classes I teach. They're great tools, and students do some truly awesome stuff with them. More and more, students want to build connected devices.  This used to require an expensive WiFi shield or Ethernet shield, or require the students to switch to developing on a Raspberry Pi. Enter the particle Photon:...Read More

The first thing we have to do is get it working! Wire it up. The MPU6050 uses a method of communication called IC2. I'm not an expert on this, but this is what you'll need to connect to an arduino uno  to...Read More
