Arduino is an amazing tool for Makers, and as I got back into Nerf and started modding, I began to wonder what I could do with Arduindo to help determine the effect of modifications. Take a look at any older Nerf video and you will find a kid firing darts on their lawn over a […]

Many of will have marveled at the feats of reverse engineering achieved by decapping integrated circuits and decoding their secrets by examining the raw silicon die. Few of us will have a go for ourselves, but that doesn’t stop the process being a fascinating one. Fortunately [Ryan Cornateanu] is on hand with a step-by-step description of

In response to an online discussion on the Electrical Engineering Stack Exchange, [Joseph Eoff] decided to prove his point by slapping together a bare-bones IV curve tracer using an Arduino Nano and a handful of passives. But he continued to tinker with the circuit, seeing just how much improvement was possible out of this simple setup. He

A Super Nintendo that has trouble showing sprites doesn’t make for a very good game system. As it turns out, Super Mario World is a lot less fun when the titular hero is invisible. So it’s no surprise that [jwotto] ended up tossing this partially functional SNES into the parts bin a few years back. But he

A traditional early project for someone discovering a love for electronics has been for many years a metal detector. This would mean a few transistors back in the day, but today it’s more likely to involve a microcontroller. [Mircemk] has an example that bends both worlds, with a single transistor oscillator and an Arduino. This type

This article describes the operation of the Schematic of Arduino Uno from the standpoint of electronic design. The majority of articles describe Arduino’s software. However, knowing hardware design enables you to move on to the next Arduino level. You can learn how to integrate an Arduino into the design of a finished product, including what

Nanoelectronics research institute IMEC and Cadence Design Systems have worked together to produce a tape-out for the industry’s first 64bit processor core as a test chip to be built in a nominal 3nm node. The tape-out project, geared toward advancing 3nm chip design, was completed using extreme ultraviolet (EUV) and 193 immersion (193i) lithography-oriented design rules

I was supporting a group of student on their graduation project. One of the difficulties they faced was on controlling an A/C unit with Arduino microcontroller. The first experiment we tried to work it out was by record the A/C remote control beam signal for each needed button by using the IRrecvDump code with IRremote
