The purpose of this project was to design a functioning digital meter to measure voltage, current, and resistance to a known accuracy. The project involved the integration of hardware and software to take an input measurement signal from a pair of high and low leads that was then displayed on an LCD per the rotary […]

In the previous posts I’ve described a simple Geiger–Müller counter and various experiments with this device. Today I would like to present Arduino project to communicate with a Geiger-Muller counter, gather data and present it to the user. The device is based on Arduino Uno, Nokia 5110 LCD and homemade shield. Currently it’s possible to

While working on a new Instructable (coming soon) I had decided to use an Arduino Uno with an LCD/button shield I purchased off of AliExpress. It’s a knockoff of the DFRobot Shield. I knew that I needed a menu for my project but was becoming so disillusioned with the terrible menu template programs available for
