A four-video series explores the analog-to-digital and digital-to-analog converters on the Arduino UNO R4, from basic concepts to building a practical electronic voice changer with just a few passive components and a dynamic microphone.
As we know, Arduino Uno includes a 10-bit ADC (analog-to-digital converter) inside its ATmega328p, which takes a signal between 0 and 5V and produces a digital value that varies from 0 to 1023. However, attempting to measure any voltage above 5V will cause some less than desirable results, such as creating magic smoke and destroying…
In this project we see the development and construction process of a solar-powered irrigation station. This also collects atmospheric data and soil moisture and sends them in real time to the cloud for remote monitoring, also independently controlling irrigation via a drip irrigation system, in order to keep the plants happy and within an adequate…
A dimmer is a device that allows you to modulate the alternating voltage to be given to a load. In this project, an ESP8266-based dimmer was created that can easily control AC loads such as motors and lights. It has the power to handle more than 1200 Watts and it is a project that can…
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…
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…
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…
[bctt tweet=”A shield for the acquisition of 8 analog signals from the Raspberry Pi board.” username=”OpenElectronics”] A shield for the acquisition of 8 analog signals from the Raspberry Pi board, which can be stacked with other boards in order to, for instance, interface a big quantity of sensors, diagnostics, environmental control and IoT applications….
The air data computer Asgard is out. It is a unit designed for DIYers, size and weight are compatible (fixation tabs have the same dimensions of standards servo tabs) with low-cost RC applications. Some aspects will be changed as per users feedback. The ADC is an essential avionics component and you can find a reference configuration for the Asgard-ADC…
Raspberry Pi enthusiasts may be interested in a new 8 channel ADC which has been specifically created for the Raspberry Pi which is capable of providing analog-to-digital conversions. Created by Chris Burgess the 8-channel ADC for the Raspberry Pi is now available to purchase for $17 or £12.56 directly from the awesome Tindie website. Chris…
