Let’s put the JeeNode Zero to work a bit, i.e. let’s repeatedly measure an analog voltage through its ADC, send the results over to another node via the radio, and display the received readings.
We’re going to need a test setup with two wireless nodes. Something like this, for example:
The top unit is an F103-based Blue Pill with an RFM69 on top, and a SerPlus on the left for programming (it can also be used directly over USB when a USB-enabled Mecrisp is installed).
