In this project, you’re going to build an Android app using the MIT App Inventor software that allows you to control the ESP8266 GPIOs. First, watch the video demonstration To learn more about the ESP8266 use the following tutorials as a reference: Getting started with the ESP8266 ESP8266 web server with NodeMCU Flashing NodeMCU firmware ESP8266 troubleshooting […]

When I was working on the next version of Common Parts Library, I realized that it would be helpful to explain why you might pick one type of passive component over another. We started off by writing “How to Select a Capacitor” last month, and are following it up with a close look at resistors

Generally, “jammers” — which are also commonly called signal blockers, GPS jammers, cell phone jammers, wifi jammers, etc. are radio frequency transmitters that are designed to block, jam, or otherwise interfere with radio communications. A jammer can block radio communications on devices that operates on a given radio frequencies within its range (i.e., within a
In the name of science, I introduced three of the worst 12V adapters (from My kingdom for a 12V adapter) to my bandsaw. What I found may shock you. Note: All pictures can be zoomed or opened at full size in their own tab. First on the chopping block, the “EH1205”. Wait! What’s this? The
Do not attempt this project if you are not comfortable working with line voltages! *** This projects shows how to create an IV (Current and Voltage) Tracer that can be used to teach the electrical characteristics of a solar panel. This project was created as part of an Electrical and Computer Engineering capstone project at
A switching voltage regulator is one of my favorite circuits. In school, they were the first circuits I built where I understood how transistors worked. In fact, they were the first circuit I saw an inductor being useful! Switching regulators are incredibly efficient when designed properly. Of course, this detail about design is important. They
I’ve decided to provide a funny Arduino concept thermometer in case its the middle of the night, pharmacies are not working, you are not feeling well and you want to check your body temperature. If you have Arduino by your side, this is a life saver! Components you will need: Arduino Uno/Nano, whatever Some breadboard
Learn how to use the Arduino Desktop IDE at its best and install it on your PC! Story Download the Arduino Desktop IDE The Arduino IDE is a cross-platform Integrated Development Environment. This means that you can run it on every Operating System. To download the Arduino IDE visit the download page and choose the

Real-world measurement requires the extraction of weak signals from noisy sources. High common-mode voltages are often present even in differential measurements. The usual approach to this problem is to use an op amp or an instrumentation amplifier and then perform some type of lowpass-filtering to reduce the background noise level. The problems with this traditional
