Now that party season is slowly coming towards us, some interested enthusiasts may be looking for a way to mix the enjoyment of the hobby and something different to show off to others. One example of this is a robotic bartender, and following the detaila by Instructables member D_Vee you can make your own with a little effort.
The system is controlled by an Arduino or compatible board, with an LCD display and numeric keypad for the user interface. Six peristatic pumps are used to draw fluids are controlled by the Arduino depending on the drink recipe selected by the user. With a little timing calibration and priming the system can be quite effective, and used to generate all sorts of cocktails.

If you're looking for a simple way to control many relays and thus pumps from your Arduino, without using up all your digital I/O pins - check out our Relay8: driver shield:
So what is the RELAY8:? It's a great Arduino shield that allows you to drive up to 8 relays from your Arduino using just 2 I/O pins with this shield. It communicates with your board using I2C, so you can even stack several shields together to drive 16, 24, or more outputs! Includes back-EMF protection and works with a wide range of relays. Perfect for home automation projects! For more information and to order, click here.
