Most Arduino boards have an ADC chip with a 10-bit resolution that can output values from 0 to 1023. Popular boards like the Arduino Uno, Nano, Micro, and Mega are great examples of this.
Makers, of course, use it to build many of the projects exhibited at the Maker Faire, for example. Arduino is a key tool to learn new things.
Canadian electronics geek and nascent YouTuber [Technoyaki] wanted to measure 20 volt signals on his Arduino. One might typically use a voltage divider to knock them down to the 5 volt range of the… ...
[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...
Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...
Unless you’re experienced in programming in the Wiring language, on which the Arduino language is based, you’ll want to start with the included examples, which are in the Sketchbook.
Connect the blood pressure device to analog pin A0 of the Arduino 101* platform. For this example, use the angle rotary sensor to simulate the blood pressure device. int pressure = analogRead (A0); ...
For example, Arduino can detect when the bot bumps into something, but has to rely on the phone to decide on what to do next. As we're wrapping up, the bot turns towards me and says, "Hello, Miran.
The Arduino has long since proven itself to be one of the biggest boons to DIY heads since the soldering iron, but that doesn't mean it's not still able to impress, as amply demonstrated by this ...
