In this tutorial, I’m going to show you how to create a script that cartoonizes images with OpenCV on Raspberry PI. Besides its core functionalities in Artificial Intelligence, OpenCV can be used to manipulate images. With the support of Python, you can use your Raspberry PI to transform every image into a cartoon image. What […]

Because of their low price, mini button switches are useful for many purposes. We have already analyzed how they work (ref. Using mini Switch Button with Raspberry PI and Python) and a funny use case (ref. Reaction Game (v2) with Raspberry PI and Mini Button Switch). One more way to use these buttons allows people

In a previous article we saw how to use a mini button switch with Raspberry PI. In this tutorial we are going to apply what we have learned to create a small reaction game. It uses cheap circuit components (mini button switch, resistors, LEDs and wirings), Raspberry PI and a little of Python programming. Differently

Raspberry PI GPIO ports are a really useful resource and allow PI to interface real world with a wide number of external sensors. However, some projects requires so many connections with many sensors/devices that the rich 40-PIN GPIO can become limited. In these cases you can get help from a simple and cheap electronic piece:

Tilt ball switch are small and cheap electronic sensors able to detect inclination. While not being as accurate like accelerometers, they are small, inexpensive and easy to use. For this reason tilt ball switches are popular for toys and gadgets. Tilt ball switch are usually made of an internal cavity with a free conductive mass

Active buzzer is a cheap electronic component able to produce a sound when powered with a DC current. Differently from passive buzzer, this element includes a built-in oscillator. This allow user to make it working by powering on and without the need to simulate an electronic square wave. It includes 2 rear pins. The longer

Passive buzzer is a cheap and simple DC powered element able to generate a multi tone sound if triggered with low voltage current. Passive buzzer differs from active buzzer because active one has an internal oscillator able to generate sound when simply activated with a continuous trigger. Passive buzzer, instead, needs a square wave trigger
