I went with the ProTrinket originally because there was a wiring diagram I could understand (not a hardware person). I need a similar picture for the Mayfly. I don’t understand what the following means: “First you need to enable the pullup resistor on pin D10, which is already built in to the Mayfly…[Read more]

I have a pair of wires that come out of the tip bucket. I need a connector from the wires (each wire contains two wires for a total of four) to the Mayfly. I searched the forum and saw a description for the Grove 4 pin terminal board. But it seems to need to connect a power wire. There…[Read more]
