There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

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 ...

All of the tools you need to work with the FPGA Arduino — the Vidor — are now in the wild! We reported earlier that a series of French blog posts finally showed how all the pieces fit together to ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

This week I will outline a project for Halloween that uses the Arduino and a light to create a glowing effect inside a pumpkin. I use artificial pumpkins for projects like this so I can reuse them in ...

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 ...
