Inside each of these slinky felines is pretty much what you’d expect to find — 25 or so switches and an Arduino Pro Micro. Interestingly enough, the switches are all lever-action and not push ...

PD Micro is the first Arduino-compatible board with USB Type-C Power Delivery, which allows your project to make use of voltages from 5-20 V. It’s ...

Each led in both is connected in series with a 1kΩ resistor to limit current. One Leonard-Micro difference is with the ‘built-in’ led. In the Leonardo, an op-amp between the ATmega pin and the led ...

The Arduino reads the state of the turn signal switches, and if they flick on momentarily it changes the pin from an input to an output and brings it high for three seconds.
