While simulating an Arduino isn’t a new idea, a recent project by [LRusso] provides an open source JavaScript simulator that runs in your browser. You can try it out live or host it yourself if you prefer. The simulator looks much like the standard IDE, so there isn’t much to learn. You can select from […]

In this guide, learn to construct a frequency counter device utilizing an Arduino UNO board. This device showcases signal frequency values on a 1602 LCD screen. It is designed specifically to measure the frequency of PWM signals that have a peak voltage of 5V. Hardware Required: Sure, here’s a rephrased list of the components needed

When we first saw [Maarten Tromp]’s article about a “momentary latching switch” for guitar effects pedals, we have to admit to being a bit confused. When it comes to push-button switches, “momentary” and “latching” seem to be at odds with each other, with different mechanisms inside the switch to turn one into the other. What gives?

Spare a moment’s pity for the process engineer, whose job it is to keep industrial automation running no matter what. These poor souls seem to be forever on call, fielding panicked requests to come to the factory floor whenever the line goes down. Day or night, weekends, vacations, whatever — when it breaks, the process

There was a time when plotters were the pinnacle of computer graphics output. While they aren’t as common as they used to be, there are some advantages to having a plotter. [Symon] wanted a plotter and decided to make one from scratch. Truthfully, he wants to build a CNC machine, so the plotter is just a

Guitarists will do just about anything to get just the right sound out of their setup, including purposely introducing all manner of distortion into the signal. It seems counter-intuitive, but it works, at least when it’s done right. But what exactly is going on with the signal? And is there a way to simulate it?

CircuitPython is a branch of MicroPhython designed to simplify education and experimentation on low-cost microcontrollers to make it easy to prototype without any upfront desktop software downloads. With CircuitPython, you can write clean and simple Python code to control your hardware instead of using complex low-level languages like C or C ++. While we have seen several boards

Torex Semiconductor Ltd. has launched the XDL605/XDL606 series of AEC-Q100 compliant, ultra-small step-down “micro DC/DC” converters which have an integrated coil and control IC. A DC/DC converter power supply circuit can be constructed simply by adding a ceramic capacitor and a resistance for voltage setting to the external components, which can contribute to substantially reducing

SwitchBlox is an open-source ethernet switch designed by Josh Elijah, who is the founder of BoxBlox. It was designed to make life easier for robot and drone developers or anyone who needs to use an ethernet switch. The switch is tiny, thereby making it easy to use in size constrained areas. According to Josh, there’s currently no option
