Teaching an Arduino UNO R4-powered robot to navigate obstacles autonomously

The rapid rise of edge AI capabilities on embedded targets has proven that relatively low-resource microcontrollers are capable of some incredible things. And following the recent release of the Arduino UNO R4 with its Renesas RA4M1 processor, the ceiling has gotten even higher as YouTuber Nikodem Bartnik has demonstrated with his lidar-equipped mobile robot. Bartnik’s project started with […]

Arduino Nano ESP32 becomes an ultra-low-powered, pocket-sized Linux PC

While many users get them confused, microcontroller development boards and single-board computers are very different things. Single-board computers can run full operating systems, like your desktop PC or laptop does. Microcontroller development boards, like those from Arduino, are usually limited to simpler firmware. But as microcontrollers become more powerful, the line gets blurrier. To prove […]

Experiments in PID control with an Arduino UNO R4 Minima-powered robot

In robotics and several other disciplines, PID (proportional-integral-derivative) control is a way for systems with closed-loop feedback to adjust themselves according to sensor data without overshooting the target. Drones, for example, use PID control to remain stable without wild oscillations caused by over-correction. But implementing PID control can feel overwhelming, so Adam Soileau from element14 […]
