Using a Buzzer with Arduino

Using a Buzzer with Arduino

by | 23 Nov 2020 | Tutorials

It is possible to emit sounds using a microcontroller by connecting a buzzer to one of its outputs. When you want to create a user interface, it is nice to have feedback according to the actions performed, whether it is a display, a light that lights up or changes...
Using a WS2812B LED ribbon with Arduino

Using a WS2812B LED ribbon with Arduino

by | 23 Nov 2020 | Tutorials

LED ribbons are made up of a succession of addressable RGB LEDs, i.e. the brightness and colour of each LED can be set independently. There are several ribbon models: single colour, non-addressable, 5 or 12V, etc. Pay attention to the model you want to use. Hardware...

Implementation of the moving average in Arduino

Implementation of the moving average in Arduino

by | 2 Nov 2020 | Tutorials

An analogue sensor sends a voltage level, usually between 0 and 5V, representing a physical value. This voltage can be subject to measurement noise (electronic interference, electromagnetic interference, measurement accuracy, etc.). In some applications, you will need...
Implementation of the debouncing logic on Arduino

Implementation of the debouncing logic on Arduino

by | 2 Nov 2020 | Tutorials

Anti-bounce or debouncing logic prevents the detection of parasitic changes of state of a sensor. When using sensors returning discrete states, such as a push button, it can happen, for mechanical or other reasons, that changes of state are detected that do not...

Using a multiplexer with Arduino

Using a multiplexer with Arduino

by | 2 Nov 2020 | Tutorials

The multiplexer is an integrated circuit made up of logic circuits allowing several signals to be concentrated on the same output (mutiplexing or mux) or to connect an input to one of its N outputs (demultiplexing or demux). In this tutorial, we will see the use of...
