While building robotics projects, the importance of controllers and motors cannot be overstated. These components are the heart and soul of any robotic system, providing the necessary control and ...

Connect one of the servo’s yellow signal wires directly to Arduino pin 9, and the other servo’s signal wire directly to Arduino pin 10, as shown in the circuit diagram in Figure 10-4. 3.

“Each of the 12 segments consists of a servo motor, a C-bracket, a side bracket, a wire clip and a set of Lego wheels. Two screw holes is to be drilled into the Lego wheel axle to permit it to ...

If you need a seven-segment display for a project, you could just grab some LED units off the shelf. Or you could build something big and electromechanical out of Lego. That’s precisely what ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagi… ...
