Some time ago I started writing about connecting Arduino to cellular network. Using standard GSM AT commands, a program running on Arduino can place and take calls, send and receive SMS, shoot pictures, access the Internet while monitoring phone’s battery level, signal strength and connection status. For many of these tasks any old phone works quite well, however, there are times when a specialized piece of hardware is desired. Today I’m going to talk about one such piece of hardware which can be connected to Arduino board using USB Host Shield.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
