We all are familiar with dice and often played LUDO or SANP SIDI (Snake & Ladders) game by using dice. Dice is a squire type solid box which contains 6 different numbers on all of its sides. We throw dice on a surface to get a random number while playing the games. In this project we have tried to replicate it with a digital dice using arduino uno board.

In this project we are going to design a 25V range digital voltmeter by using ATMEGA32A microcontroller. In ATMEGA, we are going to use 10bit ADC (Analog to Digital Converter) to build a digital voltmeter. Now the ADC in ATMEGA can not take a input more than +5V, so for getting a higher range we are going to use a voltage divider circuit.

Build a pocket-sized Arduino game console with 10 arcade games, Snake, Tetris, Pacman & more. Full wiring diagram, Arduino code & step-by-step assembly guide included.

Complete guide to building a precision digital micro ampere meter using STM32. Measures nA to mA with OLED display. Includes circuit, PCB files, firmware & 3D enclosure. DIY ampere meter DC digital.

ADC is the Analog to Digital converter, which converts analog data into digital format; usually it is used to convert analog voltage into digital format. Analog signal has infinite no of values like a sine wave or our speech, ADC converts them into particular levels or states, which can be measured in numbers as a physical quantity.

The BeetBox is a simple instrument that allows users to play drum beats by touching actual beets. It is powered by a Raspberry Pi with a capacitive touch sensor and an audio amplifier in a handmade wooden enclosure.

Tachometer is a RPM counter which counts the no. of rotation per minute. There are two types of tachometer one mechanical and other one is digital. Here we are going to design an Arduino based digital tachometer using IR sensor module to detect object for count rotation of any rotating body

In this DIY project we make a Digital clock by multiplexing four- 7 segment displays using Arduino UNO and displaying the time in HH:MM format. This tutorial covers all the DIY instructions, circuit diagram and required code.

In this article, we discussed how the RTC Module works and how we can interface it with Arduino to build a DIY Arduino digital clock.
