a.k.a. the gratuitously complicated bidirectionally communicating Arduino-based scrolling Twitter display and notifier. —- This project was mainly done as an excuse to learn how to use character LCD displays with my Arduino, and figure out how to make a bidirectional serial protocol. One major design goal was that the hardware would take user input and

This is a instructable for a very simple Arduino controlled electric lock. The key idea here is to be very simple as this was more of a proof of concept prototype type of thing. The Arduino is used as a switch to control the lock itself, and is set to interface with a Computer. The

My car has only parking sensor for the Reverse, so when I enter the Garage there is no way to know if I am close enough to the wall to allow the door to close or too close that I can hit the wall with the car. So, decided to build a parking sensor that

What do I need to start? The hardware requirements to start is: *Note: where can I purchase the material with all the components to build myself the system: http://iwup.altervista.org/shop/reference_list.pdf 1.-) Arduino UNO with USB cable 2.-) Ethernet Shield Arduino 3.-) Relay (for arduino 5 V) 4.-) Router Belkin (we recommend N150 or N300), also TPLink

A while back I saw an EMF (Electromagnetic Field) Detector at makezine.com that used a led bargraph. I decided to modify it to use a 7-Segment LED Display! Here’s my project. Sorry I don’t have any pictures of it in use. Hopefully I can post some soon. Credit goes to Aaron ALAI for the original

Hey everyone, I finally finished my touch panel for my bedroom wall and am here to show you how i made it. Unfortunately its not installed in my wall yet as I might be moving and don’t want to make anymore holes in my walls, but its coming with me and has already proven itself

Using a dual 7-segment display, a DS18B20 temperature sensor and a couple of shift registers I figured that I could build a digital thermometer. Step 1: Temperature Sensor The sensor I’m using is the DS18B20, it’s a 3pin sensor that just requires a single input pin from the arduino. Multiple sensors can be hooked together,

As hard as it might be to believe, I had never built an electronic clock of any kind. I’ve always thought electronic clocks were passe and not worth the time to design and build one. In addition, I thought that all interesting electronic clocks designs had already been built so why bother building an also

I was supporting a group of student on their graduation project. One of the difficulties they faced was on controlling an A/C unit with Arduino microcontroller. The first experiment we tried to work it out was by record the A/C remote control beam signal for each needed button by using the IRrecvDump code with IRremote
So one of my last projects was adding a weather vane to my Arduino weather station. https://www.instructables.com/id/Arduino-Wind-Chill-Machine/ https://www.instructables.com/id/Arduino-Weather-Station-Part2/ This Lazy Old Geek decided to add a rain gauge to it even though we don’t get much rain in the high desert. Most digital rain gauges are based on something called a tipping bucket. Here is
