The microcontroller based voting machines made the process of voting and counting the voted lot easier than before. Previously the votes were marked in paper which are then stored safely in a box and inside a well secure room for days. The process of separating the votes and counting them manually may take a lot of days. …

In this instructable we’ll be making some centrally controlled wireless RGB lamps, that responds to music and sounds in the environment! In addition to instructions, the instructable contains: Schematics List of components Link to the code so you can make and modify your own project Step 1: Planning Ahead …

Hello everybody hope you’re doing well, in this instructable I’m going to show you how to make a wireless motion alarm system, this device consists of a transmitter and a receiver. So essentially it is a pretty simple and basic wireless motion alarm system with light indication. Besides being fairly useful it is also a …
In this project, you will turn the Arduino into a thermometer! Use a temperature sensor to measure your skin temperature, and register the output with three LEDs. Even though the Arduino is a digital tool, it can interpret signals from an analog input, like the TMP36 temperature sensor, using the built in Analog-to-Digital (ADC) converter, …

I’ve settled on the lighting industry standard of DMX as my overall control protocol as I explore the world of blinky lights. This universal control method is electrically robust, radio transmissible, and flexible enough for my needs (not to mention the needs of major concert, theatrical, and entertainment venues.) There are a variety of DMX …
I often run out of digital pins on my Arduino. Anything as complicated as, say, a video game controller, was near impossible with the amount of pins I had available. Multiplexing buttons works, but it requires lots of connections and soldering. So, I put together a solution! Step 1: Resistor Dividers in Five In a …

So one of my last projects was adding a weather vane to my Arduino weather station. https://www.instructables.com/id/Arduino-Wind-Chill-Machine/ https://www.instructables.com/id/Arduino-Weather-Station-Part2/ This Lazy Old Geek decided to add a rain gauge to it even though we don’t get much rain in the high desert. Most digital rain gauges are based on something called a tipping bucket. Here is …
The TiltKey is a keyboard input device based on tilting. Based on the angle that it is tilted at, and the direction it is tilted in, you can write every letter of the alphabet, every number, and every symbol found on a standard US keyboard. Operation is very simple; the LCD display shows the letter …
Let’s measure distances with an ultrasonic rangefinder (distance sensor) and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to read a pushbutton and PIR motion sensor with Arduino’s digital input, …

This Instructable will show you just how easy it is to add extra inputs to your Arduino. You can use this technique to add hundreds of extra inputs to your Arduino with only two wires by using a fancy communication protocol called i2c (eye-squared-see). What I have used… PCF8575 SMD to DIP breakout board Teensy-Arduino (any Arduino will …
