Overcurrent relays with inverse definite minimum time (IDMT) characteristics are widely used in power systems to protect ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

As we work on projects we’re frequently upgrading our tools. That basic soldering iron gives way to one with temperature control. The introductory 3D printer yields to one faster and more capable. One ...

I have been delving (groping blindfold, more accurately) into the Arduino compiler adaptation code to try to determine how it handles the switch-over between its pwm activities, its set-I/O-to-output ...

One of the great things about home automation is that it’s limitless. Whether you add more smart locks, toss some smart light bulbs into lamps, or add another smart thermostat to your home, it’s ...

Google Authenticator is an app that generates one time passwords (OTPs). These passwords are often used as a second factor of authentication, along with your normal password. OTPs work by having a ...

The table shows the pin configuration of the Arduino UNO–based robotic arm. The red (VCC) wires of all servos are connected ...

“Arduino Self-Timer” project presented here is a low-component count 60 seconds countdown timer. It can be powered from a 9V compact battery or suitable Arduino AC mains adaptor. Working of the ...

I have been trying to work out how to use the the timers within 8bit AVR processors through the Arduino IDE, but in modes not covered by the IDE. Lots of people have put up code, often two or three ...

Electronics designer Patrick Thomas Mitchell has returned once again to Kickstarter to launch his new Raspberry Pi and Arduino programmable timer aptly named the Ninja Counter. The programmable timer ...
