In this tutorial you will build a dice that is shaken by holding the button in and thrown by releasing the button. The shake, throw and number thrown are animated and displayed on a seven segment display. A 74HC595 IC is used to interface the 7-segment display to the Arduino, using only 3 Arduino digital …

A digital clock is a type of clock that displays the time digitally (i.e. in numerals or other symbols), as opposed to an analog clock, where the time is indicated by the positions of rotating hands. The clock/calendar provides seconds, minutes, hours information. The clock operates in either the 24-hour or 12-hour format with AM/PM …
Oscilloscopes are an essential tool for electronics hobbyists and professionals to verify that their designs would work as expected. PC-based oscilloscopes score over standalone oscilloscopes due to their compact size, low cost and ability to do offline analysis. Here we describe how you can make your own oscilloscope at a very low cost using your …
This post is based on the work made previously by tomek in wiring LCD displays using 4 bits. The basic idea is to group the 7 pins that are needed to drive the LCD in only 3 using a shift register. This is a cheap alternative to serial LCDs. The schematic shows that wiring the LCD is …

I have always wanted to make something with my LED dot matrix display, and so when I found a old alarm motion sensor I knew just what to make, a Motion Sensing Eye! This instructable will hopefully finish with you having a working dmd, that will display an eye that opens if something in …
Here we will be learning how to make a color sensor. my model consists of three cardboard compartments containing an LED – one red, one blue, and one green – and an OP550B phototransistor. The LED’s shine simultaneously on a solid colored card. The phototransistors are connected to an Arduino Uno, which converts the relative …
PID Thermostat This is a PID thermostat for the arduino. It supports independent tuning parameters for multiple hardware ‘profiles’, and includes an autotune mode to estimate the PID parameters for a given setpoint. Installation Hardware DS18-series (I’m using the DS18B20) temperature sensor Solid-state relay rated for your power source 16×2 LCD display (I’m using the …
Introduction In my first article using the Arduino 2009 board, I described a simple temperature sensor interfaced using Visual Basic. I have developed the board and Visual Basic code to give a fairly usable indoor weather station. Overall Operation The Arduino 2009 acts as a standalone weather station. It does not display the data. It can operate …
We all are quite familiar with Electronic Voting Machines, where your vote gets registered electronically and you don’t need to use ballot paper to vote in election. Today security is a major concern and it also needs to be ensured that someone can’t vote twice, so this problem can be solved by introducing Finger Print …
