Jorge Aparicio c918a995d7 make the puzzle dongle app operate on channel 25 
and adjust puzzle-radio starter code accordingly

this reduces the chance of people using puzzle-radio with the wrong dongle
app (i.e. loopback); that would lead to them getting response different than
what's indicated in the text

I have also added the app name to the dongle / serial-term output:

``` text
deviceid=75fa82ad7588b3c7 channel=20 TxPower=+8dBm app=loopback.hex
```

Pre-made applications for the nRF52840 Dongle.

These applications will be used in the beginner workshop.

Getting familiar with the hardware

TODO review for accessibility

LEDs

  • The green LED (LD1) is connected to pin P0.6
  • The red channel of the RGB LED (LD2) is connected to pin P0.8
  • The green channel of the RGB LED (LD2) is connected to pin P1.9
  • The blue channel of the RGB LED (LD2) is connected to pin P0.12

Both LEDs are mounted near the USB connector.

Buttons

  • The Reset button is mounted sideways near the edge of the board that's opposite of the USB connector.
  • The SW1 button is connected to pin P1.06. This round-ish button is right next to the RESET button but closer to the USB connector.
