Have you ever found yourself stuck in traffic, wishing the lights would change faster? Or have you ever noticed that the traffic lights in your area seem poorly timed, causing frustrating backups and ...

The 74HC595 shift register provides 8 outputs from the use of only three digital pins on an Arduino. Multiple 74HC595 shift registers can be chained together, and still only consume three digital pins ...

Want to know how to interface an Arduino with a Radio Control Transmitter? Read on to see how. Signals from the Arduino can be sent to the transmitter as a result of this interface. The arduino signal ...

Real-time data acquisition from Arduino over serial and frequency analysis using the Fast Fourier Transform (FFT). Built as a practical signal processing toolkit for embedded sensor systems. Captures ...

A sound sensor is a simple, easy-to-use, and low-cost device that is used to detect sound waves traveling through the air. Not only this but it can also measure its intensity and most importantly it ...

[Leigh] is a HAM operator (you may know him as wa5znu). He is familiar with a signal visualization tool called a waterfall which plots signal strength and frequency over time. He wanted to build his ...

Abstract: This paper presents a simulation of a buck converter using pulse-width modulation (PWM) signal frequencies and duty cycles generated by an Arduino microcontroller for solar panel application ...
