Longtime artist Jeff Leonard has built a pair of Arduino-driven CNC painting machines with the motivation to grow his toolbox and expand the kinds of marks he could make simply by hand. By pairing the formal elements of painting with modern-day computing, the Brooklyn-based Maker now has the ability to create things that otherwise would’ve never been possible.
Machine #1 consists of a 5’ x 7’ table and is capable of producing pieces of art up to 4’ x 5’ in size. The device features a variety of tools, including a Beugler pinstriping paint wheel, a brush with a peristaltic pump syringe feed, an airbrush with a five-color paint feed system and five peristaltic pumps from Adafruit, a squeegee, and pencils, pens, markers and other utensils.
In terms of hardware, it’s equipped with three NEMA 23 stepper motors, three Big Easy Drivers, as well as an Arduino Mega and an Uno. There are two servos and five peristaltic pumps on the carriage–the first servo raises and lowers the tool, while the second presses the trigger on the airbrush. An Adafruit motor shield on the Uno controls the pumps, and the AccelStepper library is used for the Big Easy Drivers.
Every Tuesday is Art Tuesday here at Adafruit! Today we celebrate artists and makers from around the world who are designing innovative and creative works using technology, science, electronics and more. You can start your own career as an artist today with Adafruit’s conductive paints, art-related electronics kits, LEDs, wearables, 3D printers and more! Make your most imaginative designs come to life with our helpful tutorials from the Adafruit Learning System. And don’t forget to check in every Art Tuesday for more artistic inspiration here on the Adafruit Blog!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
