The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

If you use the analog inputs of your favorite microcontrollers, sooner or later you have needed to check their linearity and accuracy over the entire range of input values. This precise and compact ...

The project illustrates the driving of analog meters using PWM outputs from Arduino as well as the LCD Smartie program. A small current is typically required by meters to operate wherein a typical ...

Analog references are common to microcontrollers that have ADCs. Even if you’re not working with an Arduino, read through the article and use what you learn with your uC of choice.

Acquisition software Clone or download this repo and then: Connect the Arduino to the computer via USB and connect your analog signal input to the A0 pin of the Arduino. The ground should also be ...

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

The Arduino micro-controller development platform has received a lot of attention from hobbyist (makers) as well as university engineering programs. The ability to perform simple, yet effective, ...
