mrpete222 on YouTube has another great video in his WHAT MAKES IT WORK? series, this time on thermocouples! Check out the video for a great explanation of how a thermocouple built from a few pieces of metal can output very accurate temperature measurements. You can even see how to build a simple thermalcouple with a few strands of wires. Be sure to see the Adafruit learning system guide on thermocouples for more information on them too!
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.
