Completing your own Arduino projects is a great way to learn electronics and new skills. In the past, we have covered a few interesting Arduino projects that involve building robots to mix drinks. The 6-Shooter is an Arduino drink mixing station you can build using a Geekduino, Neopixel rings, RobotGeek Sensor Shield, and a few other parts.
The 6-Shooter can mix 6 different drinks with a single pump. Just select your drink, push the button, and the rest is easy. RobotGeek has shared the instructions for this project here.
