I am showing a method of using a CdS photoresistor to control a standard triac dimmer circuit that is wired to an electric drill motor (a universal motor). The CdS photoresistor is driven by an LED that is controlled by a PWM pin on an arduino microcontroller. This system provides a very easy way to control 120V AC devices with a single PWM pin, and not use any timing code or method to detect the zero-crossing of the AC power since this is done intrinsically in the circuit. It also offers true electrical isolation between the AC line voltage and microcontroller.

This is a tutorial about making an Arduino board on a breadboard! It is useful to be able to do this as its much cheaper once you have the infrastructure to use it (cables, tools ect...) and if it breaks a replacement isn't that expensive. This video is also the first of the arduino workshop projects in which I will make fun 30 minutes arduino projects. I spent a while making this video so I hope you enjoy it.

Super Car Utilizes an Arduino and is controlled via a Wireless Playstation2 Controller. Also controllable via Serial and TV Remote as demonstrated in my other videos: Video Dialog: The car's original remote is inside this Altoids Tin. This is the wireless receiver for the Playstation 2 gamepad. Here are the connections for the PS2 controller as well as the voltage divider for the battery gauge and other power wires. (This is the gear control switch, rigged for LOW currently.) The horn, digital potentiometer chips for the car remote and the voltage regulator for the car remote are here. The LCD screen displays 3 screens with current internal program values as well as the fuel gauge. A quick demonstration of how to control the car via the PS2 gamepad. Now for a drive! This car was designed with digital proportional drive controls and I have been able to replicate this control via the analog joysticks of the PS2 gamepad. Thanks for watching!

2 Homemade RGB LED-Strips controlled by an Arduino board. Each LED-Strip is seperated in 3 segments, those are driven by BD140's. And each LED-Strip has RGB colors, those are driven by BD139's. Here is a sketch for driving of one color led for one segment. img837.imageshack.us

I used a 120 sec voice recorder chip alongwith the arduino .. The arduino was just used as a voltage regulator

This is my first attemp on led matrix 6x8 grid multipxexed usb is only for powering the arduino because i damage the onboard voltage regulator the rest of the letters later

One of the first test projects I built with my Arduino. The LEDs come on a flexible 5m roll and can be stuck to anything you want. [In the video I've put masking tape over them since they're really bright.] The Arduino is powered by an external power adapter delivering 12V, which is reduced to 5V by the internal voltage regulator. The LEDs are switched using high power NPN transistors via PWM. The display is a 4-line standard LCD from RS Components using a 4-bit parallel interface and the LiquidCrystal library.

Basic electronic components to support your Arduino-programmed ATMega chip. Note: I used a 5V switching power supply...if you don't use a switching one, you need capacitors and a voltage regulator too!

The pin that would normally connect to the 3.3v output of the FTDI chip on the official Arduino boards actually connects to 5v on the 5v Sparkfun board! While this is more of a Sparkfun issue, theres another side effect, if theres a voltage difference between the FTDI chip and the regulator, it's quite possible for the regulator to cause harm to the FTDI, this, in my and my dads opinion really isn't a brilliant idea In the video you can see I cut the track between the 3.3v regulator and the 3v3 pin, this allows the system to run perfectly.
