Arduino Project – Touch Me Not I modified the Arduino project from the Arduino Starter Kit (Touch Sensor Lamp). Now it lights up an LED when your hand is close on the aluminium foil (without even touching it). This can be used as a ‘Touch-less Switch’. I just did it because it seemed pretty cool …
We know the analog potentiometer , is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider . MCP41100 an Arduino Controlled Potentiometer: 1)volume controls on audio equipment. 2) Control the amplifier Gain and offset . 3) Transducer ” displacement transducers “. and many Other application , But did you you want to …
In this project we are going to make an IOT Based Air Pollution Monitoring System in which we will monitor the Air Quality over a webserver using internet and will trigger a alarm when the air quality goes down beyond a certain level, means when there are sufficient amount of harmful gases are present in the air like CO2, …

Have you ever wanted to make a project that involved contact-less sensing? For example: to detect a door closing, to count the number of revolutions of a wheel, or make a speedometer? Then this Arduino Hall Effect sensor tutorial is for you! This project uses a Hall Effect sensor to detect the presence of a …

The Force Sensitive Resistor, or FSR is one of those parts that fills bins in interaction design labs across the world. It’s a simple guy, a finicky guy, but it has its place in the maker toolbox. A FSR is just what it sounds like – a resistor that changes its resistance with force. So …
Felxiforce is a force sensor that is very similar to FSRs we just wrote about in principal. They change their resistance when you apply force to them. (The flexi part of the name is because they are flexible) Felxiforces are about twice as expensive as their FSR cousins, but these are much more stable, and are calibrated …
Most technology Instructables are fun to construct, and often easy to build. This is one that shares those features, but also solves a practical problem we had. To prevent fading of furniture, carpet, and the wood flooring in our foyer, my spouse and …
In this Instructables I am going to explain about my new project called ” A Pocket Sized Touch Keyboard” .It is a Arduino based small physical device used to simplify your different keyboard operations.You plugs it into your computer usb port and touch it on the capacitive touch sensor,the sensor can be made from any …
This example demonstrates one techinque for calibrating sensor input. The Arduino takes sensor readings for five seconds during the startup, and tracks the highest and lowest values it gets. These sensor readings during the first five seconds of the sketch execution define the minimum and maximum of expected values for the readings taken during the …
Sometimes you want everything in the program to stop while a given condition is true. You can do this using a while loop. This example shows how to use a while loop to calibrate the value of an analog sensor. In the main loop, the sketch below reads the value of a photoresistor on analog pin 0 and …
