The servos are all controlled by an Arduino Uno fitted with an Arduino Sensor Shield. Everything is fitted together with a 3D printed chassis and limb segments that bolt directly on to the servo ...

This DIY solar tracker project mimics this behavior using three simple main components: An Arduino UNO board, a servo motor (with a sunflower paper decoration attached), and two photoresistors ...

Electronics-wise, this food flinger doesn’t use much more than three servos and an Arduino Uno. Servo #1 pulls the arm back until it hits a limit switch. Servo #2 holds the arm down , and servo ...

but getting an Arduino starter kit is more convenient. Most already come complete with the UNO board and a bunch of components like LEDs, a temperature sensor, a DC motor, a servo motor ...
