I have (finally) got round to building my own instance of Du Wayne, KV4QB‘s prize-winning Scalar Network Analyser Jr: and a great little instrument it is too! Du Wayne and I have been corresponding for a couple of years, sharing mutual interests. I was pleased to be able to give his work a shout in …
In this project I will show you how I combined an Arduino, an INA219 power monitor IC, an OLED LCD and a Micro SD Card PCB in order to create a power meter/logger that has more functions than the popular USB Power Meter. Let’s get started! Step 1: Watch the Video! The video gives you …
Ham radio is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, etc. Developing a ham radio project may requires using an antenna analyser, a device that is used for measuring input frequency and impedance. There are many types of antenna analyzers such as Anritsu VNA Master, RigExpert, …
Last Thursday I had a lot of fun doing a workshop at my college (UMass Amherst) where I taught students to use a Wi-Fi-enabled Color LED matrix combined with JavaScript programs to create animations displayed onto the LED matrix. The matrix is made of 5×7 WS2812 (Neo Pixel) LEDs. I’ve actually designed it two years …

Hi! Today I’ll explain you how to recover your bricked ATtiny microcontroller using your Arduino board. ATtinys are very popular due to their small form factor yet very powerful. While working with them you may accidentally brick the ATtiny. As arduino is extremely popular and really easy to use, I guess you have one or …

This post is about how to use the BMP180 barometric sensor with the Arduino. It is also applicable for other similar barometric sensors. Introducing the BMP180 barometric sensor The BMP180 barometric sensor (model GY-68) is the one in the following figure (front and back view). It is a very small module with 1mm x 1.1mm (0.039in x …
OH MySensor Platform While building my custom Home Automation system for my apartment I already designed some actuators in the form of my RGBW Controller. Several of these control the lighting in some of my rooms. To “intelligently” use your actuators (e.g. light, power, …) you need to collect some information first though. To do …
MikroElektronika, the microcontroller development boards and accessory boards manufacturer, introduced a new development board for beginners and non-experts called Flip & Click. Flip & Click is a rapid prototyping tool that is an Arduino Due on one side, and four mikroBUS™ sockets on the other side. The first side, the blue side, is Arduino Due …
Hello and welcome to my first Instructable. I will show you how to send emails from any ESP8266 Wi-Fi module using Gmail server. This instruct able relies on Arduino core for ESP8266 Wi-Fi chip, which makes a self-contained microcontroller from it (no need of AT commands and master devices). You can connect sensors and get …
Use of traffic navigation apps to minimize the wait time on road is very common for drivers these days. Google navigation gathers data from the drivers who are navigating via Google Maps and shows the traffic flow on smartphones in real time. While this is a great feature to have in smartphone, it would be nice …
