Enter the ExtraCore library for Arduino ... pins your project can control. It may not be the most practical use of two Arduinos, but it’s certainly impressive. You can pick up [Dustin]’s code ...

All of the tools you need to work with the FPGA Arduino — the Vidor ... There is one caveat. The FPGA code has a top-level block with lots of I/O pins defined and the corresponding constraints.

The on period, known as pulse width, is modulated (a.k.a. changed) via the code, allowing you to control the value sent to your components. PWM pins work the same way across all Arduino boards ...

#defines can get quite complex but can make your code shorter and more readable. The Arduino IDE uses #defines to define things like I/O pin numbers, modes, and other things. You can also create ...

Artist Jeff Leonard has created a pair of fantastic Arduino powered CNC painting machines with the aim of ... There are many different codes that I call and overlap and use as a painter overlaps ...

Code in the Arduino sketch is then used to compute the actual voltage being measured. The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format ...

all you have to do is connect the leds in series with a 470Ω resistor between the ground and the Arduino pins mentioned in the code.

The Arduino magnetic drawing machine operates using an Arduino board mounted with a magnetometer. This setup, combined with node.js and socket.io, allows the machine to detect disturbances in the ...

Learn how to build a mini CNC drawing machine using Arduino in this simple DIY project. This video guides through the process of creating an easy drawing machine at home, perfect for beginners.

doing so with a machine you build yourself is considerably more entertaining. Over on Make, they walk you through building this DIY crusher, from writing the code to getting the actuator to work ...
