### AI overview

Arduino Blog describes Kelton Serra's redesigned robotic arm, which uses puppet-style control through potentiometers, an Arduino Nano ESP32, servo motors, and a servo driver board. The redesign aims to make the arm more affordable, easier to build, and better performing, with 3D-printable parts and upgraded wrist and gripper mechanics.

### Source excerpt

Robotic arms are extremely versatile, which is the entire point. But that versatility comes at the cost of complexity when it comes to programming and control. A few years ago, Kelton Serra from the Build Some Stuff YouTube channel simplified the situation by giving his custom robotic arm a puppet-style controller. Now he's back with [...] The post Redesigning a popular robotic arm appeared first on Arduino Blog.

### AI overview

Arduino Blog describes P.A.R. (Pixel Art Robot), a 37 x 18 flip-squisk display that uses a servo-actuated robot controlled by an Arduino Nano ESP32 to flip 3D-printed square discs and render monochrome pixel art. A color sensor detects each disc's state, and an internet-connected website lets visitors submit images for display.

### Source excerpt

Flip-disc displays used to be very common in the days before affordable LEDs, LCDs, and OLEDs. But as electromechanical devices with a lot of moving parts, they're expensive and rare today. That's a shame, because they're charming. That charm is what led Zimm to the creation of this novel flip-squisk display called P.A.R (Pixel Art [...] The post P.A.R. is a flip-squisk display that draws your pixel art appeared first on Arduino Blog.
