Arduino Vs Raspberry Pi: How to select between the two?

Submitted By: 


Choosing Arduino and Raspberry PiThis is a common dilemma among electronics community of engineers whether they are DIY hobbyists or professionals working on a prototype. There may be a case that one might have worked on some microcontrollers and now willing to propel the academic excellence by working on development boards or do one needs to choose a development board for a do-it-yourself engineering project. Let's have a fundamental understanding of both the boards to make clear which to select.

First thing is that both Arduino and Raspberry Pi offer a range of development boards with different specifications and features.

Increasing the Range of RF Module by Using Antenna and Increasing Transmission Power (Project 5/12)


Venu Gopal M

Increased RF module range using power and antennaThis electronics project is a modification of RC circuit by attaching an antenna to it and increasing the transmission power for increasing the RF range. 

RF Modules are extensively used by the electronics hobbyists. They are also used in large number of consumer electronics products. These modules are used for wireless data transmission and for implementing remote control systems. The 434 MHz RF module is the most commonly used module available in the markets. These modules are capable of transmitting 4-bit data at once at a data rate of 1Kbps to 10 Kbps. Learn about the RF transmission and basic setup of the RF transmitter and receiver modules.

Increasing Range of RF Module by Using Antenna (Part 4/12)

Increase range of RF module by increasing height AntennaRF Modules are low band radio frequency communication circuits that are used for transmission of digital data over small distances. Hence these modules are quite useful in making consumer electronics products or DIY projects for home or office environment. The 434 MHz RF module is a standard RF transmission product that is extremely popular and extensively used by hobbyists and the product engineers. Learn fundamental details about the RF communication and the basic setup of RF transmitter and receiver.

These standard 434 MHz RF modules have a data rate of 1Kbps to 10Kbps. They can operate over a distance of 50 to 80 meters without any antenna

Digital Clock with Stopwatch, Alarm, Countdown and Temperature Display Using Arduino and RTC DS1307


Pawan Kumar

RTC Clock with countdownAlarm Clock, Timer and Stopwatch are common time-keeping features. These functions are so frequently used that it is difficult to imagine modern life without a time-keeping application nowadays. Whether it is a scheduled wake up alarm, a stopwatch to track the time one has jogged or a timer and alarm to schedule office tasks, time-keeping is part and parcel of day-to-day life. This is an Arduino project demonstrating a complete time-keeping application. The project is a real-time clock and allows setting alarms, timers and running stopwatch. It also displays real-time weather conditions with temperature and humidity indications as add-ons.

Overcharging protection for Portable devices (Laptop, Mobile, MP3 player etc) using Arduino and RTC DS1307


Pawan Kumar

Arduino, RTC DS1307 preventing overcharge of your deviceMobile overcharging or Laptop overcharging are common problems. People plug in their laptop or mobile for charging overnight which unintentionally leads to overcharging of the device and reducing the battery life. This project allows avoiding overcharging by letting the user set a timer for charging the device. Apart from this home-based application, the project can also be used in industry environment where over-heating of machines has to be avoided by automating the time of their operations.This ideas was suggested by Jaya Prakash.

This project implements this application by switching off a connected device to the circuit according to a user defined timer.

Terrafugia TF-X – The Flying Car

The Flying CarWith airplanes, we could traverse long distances quickly but not taking us exactly where we want to go but to the nearest airport mostly while sharing the ride with other passengers. Cars will take us to a more precise location as long as it is connected by a road, but at a much slower pace. The fusion of these two technologies will get usa hybrid which retains a portionof the positives from both sides, leading to the birth of the “Flying Car”. This technology has been promised to us by the early 21st century, since the early 1950s as seen in various articles and sci-fi movies. Although the idea has been around for a long time, it could not be converted into a tangible product since it was more complicated than that which met the eye.

Virtual reality applicationsVirtual Reality is a technology which makes use of software to generate a three-dimensional environment allowing access to life-size objects. It is one of the trending technologies that has gained a lot of attention lately and is being regarded as a revolutionary concept in the technology world. As per a recent report by a website, virtual reality will replace high street shopping by 2050, where users will use VR headsets to try on their clothes and indulge in the atmosphere of a simulated store.

Arduino based Ultrasonic Radar


Ashutosh Bhatt

Servo motor and Ultrasonic SensorArduino can control the servo motor very accurately because of it has built in 8 bit PWM generator and servo motor library functions. It can rotate servo motor to desire angle very accurately as well as by reading servo motor feed back, it can read exactly the current angle of servo motor. Similarly it is very easy to interface UltraSonic Distance measurement (UDM) sensor with arduino. By connecting UDM with arduino, we can easily detect any object and get its distance.

This radar uses UDM sensor that is continuously rotated from 0o to 180 o and 180 o to 0 o using servo motor. 

DIY motion detector project with 3-axis accelerometer

Submitted By: 

Shalini Verma

Sometimes we need an extra eye for our home to detect something unusual and I am not talking about camera. From a simple home intrusion detector to testing the driving skills or to keep a check on your favorite cookie jar, you need a 3-axis accelerometer, which is the main element of this project to provide a little motion detector.

This project requires Arduino, 3-Axis Accelerometer Module, Male header pins, Grove Base Shield, Universal Cables, Grove Button and Buzzer, Mini Breadboard, Protoshield and female header pins.

Universal stepper motor speed controller


AM Bhatt

Universal Stepper Motor Speed Control ProjectStepper motor is a digital motor. It rotates as per applied pulses. The pulses have to be applied in specific sequence to motor coil terminals. The speed of motor can be varied by varying the frequency of applied pulses. As the frequency is increased the speed is increased and vice versa. Increasing frequency means decreasing time period – delay of applied pulses. So as the time period of pulses is decreased the speed of motor increases and vice versa. The maximum frequency (means minimum time period) at which the pulses should be applied depends upon the maximum RPM of motor.
