In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...

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 ...

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as any other servo tester, the difference is that it can be programmed to do ...

Makers, electronic enthusiasts and those interested in building robots may be interested in a new robotic arm project featured on the Instructables website created by Maurizio Miscio. The robot arm is ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small boards ...

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Arduino ...
