Let’s get practical with some examples of combinations of sensors working at different voltages and references for the A/D converter of Arduino. Third and final part. After getting to know and having studied in details the ADC contained in the ATmega328P microcontroller which is equipped with Arduino Uno board’s and more, and after having…
A kit for experimenting with electronics at any age by taking advantage of Arduino’s versatility and a well-equipped hardware section. More and more, electronics and programming are approaching school and students, even younger students in these last years, based on the assumption that this will decrease the training time for those that are by…
Let’s go deeper into enhancing techniques for ADC reading and let’s take a look at the first practical examples of analog data reading coming from sensors. Part two. In the first part of this tutorial we have introduced the functioning of Arduino AD converter, which is associated to the input pins A0÷A5 (ANALOG…
It is no longer a problem, nor it is expensive, to print big size items and terrain models: we showed you that by means of our new creation, the FDM 3D printer that our well-equipped readers will be able to create, thanks to the assembly kit. The machine is capable of manufacturing solid prints…
It is a newborn board, but it is rapidly growing in popularity thanks to the potential we are going to show you through the project of a robot on wheel that can be controlled by a smartphone via Bluetooth. micro:bit is a small but solid and powerful prototyping board designed by no other…
Let’s step into the word of analog-digital conversion for Arduino, by discovering how the dedicated pins work and how to use them for acquisitions. Part one. In the ADC of Arduino, an analog signal ranging from 0 to 5 V is translated in 10-bit code, which is 210 = 1024 combinations, with a…
On the hardware of the controller board LED Matrix, by taking advantage of the reconfigurability of the onboard FPGA, we can build a bivalent tool that is extremely useful to have on our work bench. If you’re looking for a tool for measuring frequency that is not the classic multimeter and, in the various…
A solid-state amperometric sensor, capable of measuring up to 5 A providing a voltage that is directly proportional to the current. There are many practical situations where we need to know the current absorption of a circuit branch, a motor or in general, an electric utilizer. Sure, we could just use a multimeter set…
