Arduino Sensor Beginners Guide
Arduino Sensor Beginners Guide So you want to learn arduino. Good for you. Arduino is an easy to use, cheap, versatile and powerful tool that can be used to make some very effective sensors. This guide is meant to give you the basics of getting started with Arduino, and provide you with some basic code that will work with many sensors. The Materials To begin, you will need 1. An ARDUINO: I personally use an ARDUINO UNO V2, but there are many different types available. For our purposes they should all work the same so if you already have one, great. 2. A breadboard: Breadboards are named after cutting boards that early circuit enthusiasts used to hold their sensors. A breadboard is used as a place to hold your sensors, resistors and wires, and also serves as an easy way to connect things together. Breadboards come in all shapes and sizes. I would recommend something like this. This will cost you about 5 dollars online. 3. Wire: Wires are essential to Arduino. They are what allow you to actually connect your Arduino to stuff. Most small, hobby wire will work. All you need to make sure is that it is small enough to easily fit into the pins on your Arduino and breadboard. 4. A Sensor: Sensors come in all shapes and sizes. Most of the guides I have written use sensors similar to these, but don’t feel restricted to these ones. Many of them work pretty much the same way. Using Your Breadboard Different breadboards are set up in different ways. -
Arduino Uno SMD
Arduino Uno SMD Overview The Arduino Uno SMD is a version of the Arduino Uno, but uses an surface mount version of the Atmega328P instead of the through-hole version. This version was made in response to a shortage in supply of the through-hole Atmega328P. The board is based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to- DC adapter or battery to get started. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter. "Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform; for a comparison with previous versions, see the index of Arduino boards.

Rushikesh S. Rakhonde, 2021, 9:1 ISSN (Online): 2348-4098 ISSN (Print): 2395-4752 A Review on Role of Arduino Uno Used in Dual Axis Solar Tracker Rushikesh S.Rakhonde, Pranay R.Lakde, Suraj K.Badwaik, Akshay B.Ronghe, Dipak P. Sonule, Asst. Prof. C. J. Shende Department of Mechanical Engg, DESCOET, Dhamangaon (Rly), Maharashtra, India Abstract- The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. The board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment), via a type B USB cable. It can be powered by the USB cable or by an external 9-voltThe battery,Arduino thoughproject itwas accepts started voltages at the betweenInteraction 7 and 20 volts. It is similar to the Arduino Nano and Leonardo. The word "uno" means "one" in Italian and was chosen to mark the initial release of Arduino Software. The Uno board is the first in a series of USB- based Arduino boards; it and version 1.0 of the Arduino IDE were the reference versions of Arduino, which have now evolved to newer releases. The ATmega328 on the board comes pre programmed with a boot loader that allows uploading new code to it without the use of an external hardware programmer.

Arduino Uno - R3 (Original - Made in Italy)
Arduino Uno - R3 (Original - Made in Italy) The UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. The UNO is the most used and documented board of the whole Arduino family. Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again. "Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

Project Documentation
Project Documentation Project Title: e-Glove Team Members: Harshit Rathore, Shubham Agrawal & Elle Atma Vidya Prakash Team Mentors: Rohit Agarwal & Divya Prakash Basic aim: To make a glove embedded with various sensors to detect hand and finger gestures, and implement those in many things, like playing games, giving presentations and many more. Motivation: We were having a look at previous year projects done under the electronics club, we saw many game controllers. So we thought of a game controller that can work for all the latest games, is full featured, and gaming looks more realistic using that. Inspired by things like Microsoft© Kinect™, Sony© Play Station™ motion controller, and many more such controllers available in the market, we came up with this idea. Theory: Sensors 1. Accelerometer: An accelerometer is a device that measures acceleration. When it is kept horizontal at rest, it measures 9.8 N/Kg downward. Whenever there is a tilt, a small component is left at the downward face, which can be detected. 2. Flex Sensor: The flex sensor is basically a variable resistor that reacts to bends. It changes its resistance when flexed so we can measure that change. The bend is only detected in one direction. TO read the data from the sensor, we need a fixed resistor (not changing) that we can use for that comparison (We are using a 33K resistor). This is called a voltage divider and divides the 5v between the flex sensor and the resistor. Microcontroller A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.
