Transforming the Adafruit Pro Trinket and nunchucky into a wireless USB mouse stick first begins by soldering the nunchucky to the Pro Trinket. The only soldering required for this entire project involves two steps:
- Solder the 4 pin header to the Nunchucky
- Solder the other end of the 4 pin header to the Pro Trinket. Before soldering the other end to the Pro Trinket make sure Pro Trinket pins are connected to the Nunchucky based on Pin A2-->Gnd , Pin A3-->3.3v, Pin A4-->Data, and Pin A5 --> Clk
A picture of the nunchucky soldered to the Pro Trinket is shown below. It is important to make sure the Nunchucky is soldered and oriented correctly with respect to the Pro Trinket.
You can use a 3.3 volt or 5 volt Pro Trinket for this project, but for the wireless Wii receiver to operate properly only a 5 volt Pro Trinket can be used!
