One of the basic tasks in many home automation systems is controlling power to appliances. They could be lights, or a heater, or an exhaust fan, or just about anything else that runs on mains power. The problem of course is that it’s dangerous to mess with mains-level power directly and you may even be […]
Hi from Italy Although many watches are created binary, my project was inspired mainly to this: http:// http://www.instructables.com/id/LED-Binary-Clock-1/, very smart and funny. I tried to improve the design and to add something personal. I think it’s a good result at the end. The project is not difficult, requires patience, it requires a little knowledge of
how you can take a computer u hv old (power supply unit) and turn it into a power supply that will power your Arduino and give you all the amperage you need as well as your standard 3.3 volts, 5 volts, and 12 volts for any accessories/electronics used on your breadboard And arduino power ,led

How to make a stripboard Arduino clone, AKA the veroduino. Once a project is past the prototype stage there is no need to use a complete Arduino, even with the ever decreasing cost of Arduino compatibles and the availability of cut down versions such as the Arduino Nano and Mini it’s still overkill for a
In the previous post, I outlined some Arduino code to generate tide height predictions for a NOAA tidal reference station. Now let’s do something useful with this newfound functionality. In the experiments I run, it’s useful to keep intertidal animals like snails and limpets on a natural tidal cycle. In addition, some animals like high-shore

Sometimes I just do not have time to connect to the internet and check current weather conditions. This is the reason why I made this indoor LCD weather display based on Atmega328 Arduino MCU. The circuit board consists of two LP2950 voltage regulators, MCU, four buttons, ENC28J60 Ethernet module and LCD12864 graphic display module. The

These days I was reading an interesting post on how to make yogurt “by the gallon” (http://www.instructables.com/id/Yogurt-By-The-Gallon/). One thing needed was to maintain a rather constant temperature of 43ºC (110°F), so the bacteria can grow properly. Though you can buy commercial yogurt makers, they aren’t big enough for a gallon of yogurt. Besides, it’s cheaper
This is an extremely cheap IR proximity sensor you can make with a few cheap parts and an AVR programmer. I use an Arduino as my programmer in this Instructable. This sensor only has a range of about 3 inches. You can easily add more LEDs or brighter ones to extend the range. You can
In this project, I am using an Arduino board to show forecast of the weather from Google Weather service on a VGA screen. The display is obviously graphical one, with icons and some colorful text. It is one of those gadgets I wanted to have for some time now – A weather forecasting display that

Hi. I’m Darren a 17 year old hobbyist, and this is the first Instructable I’m posting here, so I apologize if it kinda sucks! I hope it’s good enough… So how did the idea of a robotic arm come to me? Well, the first thing I remember is our chemistry teacher (!) coming to me
