The Arduino Mini is the smallest arduino on the market. Its tiny form factor is perfect for handheld projects, but there are some trade-offs to that size. One of the big trade-offs is the Mini’s lack of built in USB serial support. If you have an Arduino Uno though, you have an easy way to connect to the Mini and send programs to it through the Uno’s serial pins.
In this video I show you how to connect up the header pins on the Mini, and how to program it using an Arduino Uno! Let me know what you think of it in the comments below!
