   I've got a few Unos. My problem is figuring out what to do with them. I   
   don't mean the coding/peripheral aspects but projects that are something I   
   need. Right now I have a 4 wheel chassis with a primitive IR keypad   
   controller. The long range plan is to incorporate the PWM ability of the   
   L298Ns and go to the nfr240l01 for two way communication. The problem is   
   the chassis has limitations.   
      
   I've got a couple of the Nano 33 BLE Sense boards. A MIT course in TinyML   
   used them. The nRF52840 is Arm. All of the onboard sensors make it more   
   expensive but it's handier if you can make use of them.   
      
   Right now I'm messing around with the Pico W. Too many choices, too little   
   discipline...
