Hi, First of all, my English is not perfect =) I’ve seen many projects with Arduino that describes how to control 2 servo’s with a joystick or use a lcd screen. All of the projects that i have seen are all seperate things. So i decided to make a short Instructable of these things combined. …
One of the most fun and useful projects on instructables is to create your very own solar USB/ iPhone charger. They’re not overly difficult to make, nor are the parts overly expensive or hard to find. For the most part they do a rather good job of charging up small gadgets. Mostly. The big flaw …

I got my start in microcontrollers with the Arduino, as many of us outside of electrical engineering did. (And still do!) The ease of programming that little board makes it a great gateway… and like any gateway, sometimes you go through. Most of my projects now don’t use Arduinos directly. For simple microcontroller applications, it’s …

To connect a 12V relay to the Arduino you need the following things: – 1 Arduino – 1 diode for example 1N4007 – 1 NPN transistor for example 2N2222 (in the US) or BC548 (in Europe) – 1 relay for example one with coil voltage 12V and switching voltage 125VAC/10 A – 1 multimeter Step …
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 …

An old rotary phone can be used for a number of purposes in your Arduino projects – use it as a novel input device, or use the Arduino to interface a rotary phone to your computer. This is a very basic guide describing how to interface the dial to an Arduino, and get the number …
Update: check out the RFToy — an easy-to-use standalone gadget to control remote power sockets. Also, support for remote power sockets have been added to OpenSprinkler firmware 2.1.1. For a while I’ve been looking for a way to switch household power line (110V) devices. One of the simplest options is to use a relay that is connected to …

I’ve had an Arduino Duemilanove now for a couple of weeks. If you’re not familiar with the Arduino, it is “an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software”. It has a small microcontroller, a USB port to connect to your computer for programming, a power socket for providing power when the USB …
I have a device which provides a USB port. If I attach it to a Windows PC it is recognized as a “CP2103 USB to UART Bridge Controller”. According to the device documentation, it should communicate in serial format at 38400bps.I have to talk to this device with a atmega microcontroller. Since the USB pinout …
