Arduino SPI: in this tutorial we will learn what the SPI standard is and we will learn how to use it with our Arduino board. Serial Peripheral Interface The Serial Peripheral Interface (SPI) standard is a synchronous, full duplex communication bus with master / slave architecture, originally developed by Motorola. It is based on small […]

The analog of digital In this article we deal with PWM (Pulse Width Modulation), which allows us to modulate the digital signal and gives us the possibility to use it as if it were an analog signal. Let's learn PWM PWM is a type of pulse modulation, which, thanks to the action of the board's […]

In our previous article "Arduino digitalRead, digital input and buttons" we saw how the digitalRead function works and how it works. In that article we ignored some issues that the button can give us. In our projects, especially if we do not come from the electronic world, we think that if there is an error […]

Sensors, the best choice

Sensors are fundamental measurement devices for acquiring data and performing actions on such measurements. An inappropriate choice of these devices can negatively affect our project. What we are going to see today are three types of sensors: Resistive, Capacitive, Inductive. Resistive Sensors Resistive sensors are sensors that convert the quantity to be measured with a […]

digitalRead is the Arduino function to know the status of a digital input With our first project we were able to switch on or off some LEDs at our own pace, so we took care of activating or deactivating an external device via an OUTPUT signal. If, on the other hand, we want to receive […]
