Controlling a robot arm with M5Stack Cardputer 1.1 Built a robot arm control system from what I had on hand. M5Stack Cardputer is the brain, connected to a joystick and two rotary encoders through an I2C hub. Joystick controls the base and gripper, encoders handle shoulder and elbow. It creaks and crunches but it moves!)) #m5stack #robotarm #cardputer #esp32 #robotic
