Introduction Of Arduino

Arduino is an open-source electronics platform based on easy-to-use hardware and software (IDE).

Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED. You can tell your board what to do by sending a set of instructions to the microcontroller on the board.

Arduino has been used in thousands of different projects and applications. The Arduino software is easy-to-use for beginners, yet flexible enough for advanced users. It runs on Mac, Windows, and Linux.

Teachers and students use it to build low cost scientific instruments, to prove chemistry and physics principles, or to get started with programming and robotics.

How to made project

Step 1: Setup

You would need :• Arduino UNO or anything that has a computer

brain.• 10k Ohm Resistor.• Wires• LCD Display• Power cable (USB)

cont.…

Step 2: Coding..

Different foods have different resistances so Just put it into IF and ELSE loop.

● So here is the breakdown for you:• Check resistance range of different foods using Serial

Output.

• Use those resistances to make create a range.

• Serial Output the food name

Here Application Code..

Problems

System not able to read exact value of resistance using jumper wires.

We were trying to get resistance values for cut open

apple, but they kept changing abnormally from time to time.

Future scope

• This application is used by farmers to detect how much time their food stay fresh.

• With the use of this application users can also determine the test of food.

• user can also get output in the form of voice by attaching speaker with circuit.

• User can also detect inhabitant food.
