Well its been a minute since I’ve toyed around with electronics, but a $4 Raspberry Pi Pico board arriving in the mail changed that.
This board packs a boat load of utility for $4, just check out the data sheet and check out all them I2C and SPI pins!
I dusted off the last components I tinkered with, along with a handful of wires. After a couple days of tinkering, I ended up with a 433MHz radio packet receiver.

After a bit of success implementing an Arduino 2.4GHz Transceiver , I was encouraged to explore a more familiar environment, something with Python and Linux in the mix.
After a short period of research I landed on the circuitpython-nrf24l01 pypi project page, and quickly began digging through their examples .
It wasn’t long after I had a working prototype that mirrored my Arduino code quite closely:

It has been quite some time since I’ve tinkered with an Arduino, and this go around I decided to learn something new.
The [NRF24L01](http://amzn.to/3iFalxX(opens in a new tab)) 2.4GHz Transceiver is an extremely affordable wireless chip, I managed to pickup 10 units for around $12. This chip allows sending and receiving on the 2.4GHz wireless band .
Lucky for us there is a great Arduino library just waiting to be imported, thanks maniacbug !
