If you live in a less than reliable climate like England. Here is a simple 8W Class A Amplifier. I am very pleased with the sonic results of this amplifier. It really does not disappoint. Even using fairly standard 3 way. Gammon Forum Electronics Microprocessors I2C TwoWire Peripheral Interface for Arduino.

After checking that the Sensor Shield is working, it is time to load the Arduino board with the final sketch. This final sketch was built upon the Serial Event. Project Lab. Difficulty Level 5Whats thisThe Video Experimenter shield can give your Arduino the gift of sight. In the Video Frame Capture project, I showed how to capture images from a composite video source and display them on a TV. We can take this concept further by processing the contents of the captured image to implement object tracking and edge detection. Lets put together a pixel strip with an HL1606, an Arduino UNO and the Spectrum Shield to build a seven bands large Spectrum Analyzer of simple construction. Its blue Its thin Its the Arduino Pro Mini SparkFuns minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader. Arduino. The setup is the same as when capturing video frames a video source like a camera is connected to the video input. The output select switch is set to overlay, and sync select jumper set to video input. Set the analog threshold potentiometer to the lowest setting. Object Tracking. Here is an Arduino sketch that captures a video frame and then computes the bounding box of the brightest region in the image. You can download the sketch here. The code first calls tv. Then it computes a simple bounding box for the brightest spot in the image. After computing the location of the brightest area, a box is drawn and the coordinates of the box are printed to the TVout frame buffer. Finally, tv. resume is called to resume the output and display the box and coordinates on the screen. Keep in mind that there is no need to display any output at all we just do this so we can see whats going on. If you have a robot with a camera on it, you can detecttrack objects with Arduino code, and the output of the Video Experimenter doesnt need to be connected to anything although the analog threshold potentiometer would probably need some adjustment. If you use a television with the PAL standard that is, you are not in North America, change tv.

Edge Detection. The Arduino is powerful enough to do more sophisticated image processing. The following sketch captures a frame then performs an edge detection algorithm on the image. The result is the outline of the brightest or darkest parts of the image. This could be useful in object recognition applications orrobotics. The algorithm is quite simple, especially with a monochrome image, and is described in this survey of edge detection algorithms as Local Threshold and Boolean Function Based Edge Detection.
