Your Crickit contains a special interface chip we call seesaw. Like a see-saw you see in a playground, it goes up/down back/forth. In this case, instead of holding children, it sends commands and responses back and forth - motor movement, sensors inputs, signal i/o...
The seesaw code is contained in a microcontroller near the bottom of the Crickit, and that chip comes with the seesaw firmware on it already when you get it!
But we do make improvements to the seesaw firmware, fix bugs, and improve performance
So its a good idea to update your Crickit when you get it! It's easy and only takes a few seconds.
There's a little USB connector at the bottom of your Crickit labeled seesaw only! Plug a standard data-sync USB cable into that port and into your computer. You do not need to plug in the DC power jack or power the Feather/CircuitPlayground.
Do check that the switch on the Crickit is switched to ON
On the Crickit for CPX, Feather or Micro:bit, this button is next to the DC jack and is pretty large.
On the Raspberry Pi, its more compact, and is right below the status NeoPixel
If you have a good USB connection and you double-click right, you'll see the left LED turn green and the right hand little yellow LED start pulsing
