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 EasyNixie Arduino compatible low-voltage Nixie Tube driver module has emerged as a versatile and user-friendly tool for hobbyists and professionals alike. This module, designed with a focus on ...

This is where the high voltage parallel programming mode will come into the picture and is the only way to recover the device. This mode is being supported by very few programmers. The entire HV ...

Arduino Voltmeter How it Works Analog input from pin A0 is received through a voltage divider circuit to allow for the Arduino board to handle higher voltages. This is because the arduino analog pins ...

This Arduino sketch monitors the voltage output from a potentiometer connected to analog pin A0. It displays the voltage reading on the serial monitor and controls two LEDs based on the voltage level.

This project is a great example. [Scott Daniels] takes a look at the other voltage measurement options available to AVR chips used by Arduino.

The ATMega328 microcontroller as mounted on the Arduino UNO board has a 10-bit AD converter. Let’s use its function analogRead to measure some voltages with. How can we improve the accuracy of the ...

We generally measure voltages with a multimeter or a voltmeter. But you can also measure low-value DC voltages up to 5V that are generally found in electronics circuits with this laptometer and see ...
