A wireless anemometer project using ESP8266 and Adafruit’s wind sensor is shared by graham22 on github. The wind sensor provides an analog output voltage proportional to the wind speed. The ESP8266 reads in the output voltage through its A/D channel, computes the wind speed, and displays it on a web browser upon receiving a HTTP request from a client machine.

Are you looking for a simple design of a DIY remote switch for controlling your AC appliances over WiFi, this Instructable provides details of making such a switch from scratch. The project uses ESP8266 WiFi module that communicates with a phone using the Blynk app. The entire circuitry is enclosed inside a box with a male plug that goes to the wall socket, and a female input plug for your device. The controller receives the power supply from the mains socket.

A new project tutorial from educ8s.tv is about making an Arduino based analog thermometer that uses an analog voltage panel meter for displaying temperature. Today we are going to learn how to use this analog voltmeter with Arduino and make it show the temperature instead of the voltage. As you can see, in this modified voltmeter, we can see the temperature in degrees Celsius. The temperature is measured by this digital sensor, a DS18B20 and it is then displayed on the voltmeter. I really like analog dials like this one, because they give a vintage look to the projects. Let’s

An Arduino-powered soda locker project posted by Mistablik on Instructables can easily fit into his locker and can supply two different kinds of pop. It features a coin acceptor that allows you to use nickels, dimes, and quarters for purchasing the soda. Lockers just aren’t what they used to be. With so many schools moving to electronic devices for books, lockers become less of a space for your books, and more of a question of: “What am I going to do with this?” What if you could use that space for your own vending machine? In this Instructable, I’ll tell

Andy Brown explored reverse engineering the ARTESYN NXA66 regulator module to build a cost-effective bench-power supply with high current supply capability. NXA66 is a non-isolated dc-dc converter targeted at computing applications that require precise voltage and fast transient requirements of today’s high performance applications such as workstations, file servers, desktop computers, telecommunications equipment, adapter cards, DSP and data processing. He designed an Atmega328 driven controller board that would host the NXA66 and expose its functionality via a front panel consisting of seven segment display modules. I’ve included a relay between the 12V input and the NXA66 because I don’t want the
