According to the information above, signature 1 has a size of 254 x 30 while signature 2 has a size of 14 x 4. Signature 1 is the pencil body and signature 2 is the eraser head.

My serial monitor shows this when the pencil is captured inside the frame: With this technique, we can reduce the detectable objects to those with the same colors and size of a pencil. We need to check the width and height of the detected signatures and determine which size suggests a pencil. Next, we create a sketch based on the ccc_hello_world example above.

Thus, we will create two color signatures. A common pencil would have different colors for its body and eraser head. For example, we want to detect a pencil.įirst, setup the pencil as a color signature by following the setup above. We can use the data on the serial monitor to determine specific objects.
#Arduino camera projects download
Pixy and Arduinoįirst, download the Pixy library for Arduino. To learn more about using Pixymon, read its official wiki page. Similarly, setup a third color signature by releasing the button on the color immediately following the color after red, and so on. To setup a second color signature, release the button on the color immediately following red. You can add more signatures by repeating the process above except waiting for the red color on the LED. The Pixy camera should now be able to detect and track the object, wrapping the object in a rectangle with the text “s=1”. Press the on-board button again to save this color signature. If a color is distinct enough, it should appear to be shaded on the Pixymon screen. Pixymon will now engage signature setup mode and will ask you to place an object in front of the camera. Release the button once the LED color changes to red. The LED on the board should start changing color. To set up a signature, press and hold the button on the board. This means that two objects with the same color will be recognized as one. You can save up to seven different color which are called “signatures”. Here’s the catch: the Pixy camera recognizes objects through their color. Next, download Pixymon, a desktop app that allows you to set which objects the camera will be able to recognize.Īfter downloading and installing Pixymon, start it and you should be able to see a stream from the camera. Just take note of the following pin definitions: From

Other boards may be used as well since the Pixy board uses SPI communication. See image below:Īs you can see, the Pixy directly supports Arduino boards with ISP headers such as an Arduino UNO, Nano and Mega.

The Pixy camera board comes with two cables: one to be connected to an Arduino and another to be connected to a desktop or laptop.
#Arduino camera projects how to
This tutorial shows you how to use the Pixy camera to build an Arduino object detection project. This camera incorporates a microprocessor which does all the heavy image processing stuff and simplifies object detection. The special device I am referring to is the Pixy camera. However, there is a special imaging device you can use to make an Arduino detect objects. Heck, they are not even good enough to capture photos without the help of a desktop computer. The basic Arduino boards are not powerful enough for image processing.
