Trinket Ground Extension
The Trinket only has one ground pin. Add more grounds with the help of a flex perma-proto.
Cut a piece with four connections on a continuous rail to fit the three ground connections need for each component.
Take a moment to review the components in the circuit diagram. This illustration is meant for referencing wired connections - The length of wire, position and size of components are not exact.
