Arduino Uno Menu Template

While working on a new Instructable (coming soon) I had decided to use an Arduino Uno with an LCD/button shield I purchased off of AliExpress. It's a knockoff of the DFRobot Shield. I knew that I needed a menu for my project but was becoming so disillusioned with the terrible menu template programs available for the Arduino Uno. Many of which were not designed to work with this shield. I decided to make my ...

SubPos: a WiFi Positioning Solution for Places GPS Can’t Reach

Description When the world's lifeforms are forced into subterranean dwellings due to nuclear fallout, evolution into lizard people or warming of the Earth, we will require a simple method for determining our position underground. In our current age, we are still working out the intricacies associated with determining our location in areas where GPS cannot reach. SubPos provides a solution to this problem, w ...

How We Built Our Facial Recognition Ferris Wheel

At Coolest Projects 2018, we showcased the Wia platform with a facial recognition Ferris wheel! Story At Coolest Projects 2018, we showcased the Wia platform with a facial recognition Ferris wheel - if you're smiling, the wheel turns, and if you're not smiling, it stops. Today we're going to talk about how we built this project, and maybe you'll be inspired to build something like it! What we used Lego Ferr ...

Chrome Apps and serial port communication

Introduction During the development of my electronic projects, I sometimes need to develop a graphical user interface (GUI) that talks using serial communication with the devices I create. In the past, I usually chose to develop those interfaces in C# and using the .Net Framework; framework which allows a rapid development, offers great ways to customize the interface (for example the ability to use custom ...

DIY Arduino Relay Driver Shield

In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications. We designed an isolated PCB for 3 relays. By using this Arduino Relay Shield, we can operate 3 AC appliances at a time. We have put a two pin screw terminal blocks (Neutral, NO) for connecting appliances. Here we have provided PCB layout, circuit diagram, and Gerber files so that you can build or directly orde ...

LM317 smooths but doesn’t regulate

A well known power supply circuit is the capacitance multiplier. It doesn't regulate, but instead reduces ripple & noise while the output tracks at some fraction of the input voltage. The R1/R2 voltage divider determines VOUT (a VBE below VB), and must be chosen to account for the maximum ripple on the minimum VIN. If VIN is regulated, the circuit can be used purely for low-level noise reduction. In thi ...

Smart Kitchen Cube

Alexa controlled timers at a glimpse. A really fancy egg-timer with added temperature control. Story Idea Both of us like to tinker with electronics and the latest hard- and software. While most projects never get out of "early-Alpha", we wanted to create something with a prototype look&feel for quite a while now. Participating in The Alexa and Arduino Smart Home Challenge finally made us consider creat ...

IoT Based Electricity Energy Meter using ESP12 and Arduino

We all know about Electricity energy meters which are installed in everyone’s house or offices to measure the electricity consumption. At last of every month, many of us get worried about the high electricity bill and we have to look at the energy meter once in a while. But what if we can monitor our electricity uses from anywhere in the world and get an SMS/E-mail when your energy consumption reaches to a ...
