It is increasingly common for engineering degrees to include the teaching of programming in their curricula. The present work focuses on the teaching of basic Arduino IDE programming and implementation of an Arduino Uno board. The teaching of Arduino IDE programming is basic and can be applied to related careers such as Information Technology and Mechatronics. It is an appropriate model so that the students of these careers are motivated to visualize in concrete form the results of the programs developed by them. An Arduino Uno board was introduced as the main element, based on hardware and software principles for the implementation of programming practices whose inputs and outputs are HC-04 ultrasonic sensors and other components such as Buzzer and Micromotor. This work is based on the planning of a smart cane prototype that helps visually impaired people. These learnings acquired on basic programming in Arduino IDE, can be implemented in different projects where Arduino Uno is used

<span style="font-size: 9pt; font-family: 'Times New Roman', serif;">Among the major issues faced by the visually impaired people is the inability to read, and this is could be addressed by learning braille. However the scarcity of skilled instructors to teach the braille codes to the visually impaired people limits the learning process. This paper presents a psychophysical study on the ability of people with visual challenges to identify hijaiyah letters from a specially developed Arabic braille module. This module consists of six miniature solenoids that are wirelessly controlled via a Bluetooth and an Arduino Uno microcontroller. Five different hijaiyah letters were provided to the participants and were randomly repeated for three times. The participants were required to touch the Arabic braille module and state the hijaiyah letters that were displayed. With priori knowledge and initial familiarization of the braille patterns, 72.9% of the trials showed accuracy between the braille display and the stated hijaiyah letters. 20% of the participants have the highest repeatability responses of 80%. The outcome of this work showed the optimistic capability of the wirelessly controlled Arabic braille display to assist visually impaired individual to read hijaiyah braille letters and ultimately promotes independence in learning.  </span>

Visually impaired people are faced with challenges in detecting information about terrain. This paper presents a new walking support system for the blind to navigate without any assistance from others or using a guide cane. In this research, a belt, wearable around the waist, is equipped with four ultrasonic sensors and one sharp infrared sensor. Based on mathematical models, the specifications of the ultrasonic sensors are selected to identify optimum orientation of the sensors for detecting stairs and holes. These sensors are connected to a microcontroller and laptop for analyzing terrain. An algorithm capable of classifying various types of obstacles is developed. After successful tests using laptop, the microcontroller is used for the walking system, named ‘Belt for Blind’, to navigate their environment. The unit is also equipped with a servo motor and a buzzer to generate outputs that inform the user about the type of obstacle ahead. The device is light, cheap, and consumes less energy. However, this device is limited to standard pace of mobility and cannot differentiate between animate and inanimate obstacles. Further research is recommended to overcome these deficiencies to improve mobility of blind people.

<p>The joy we derive from our ability to commute and interact freely with the world as a result of our possession of sight with the naked eyes are enormous however the Visually impaired people find great difficulty in moving around freely without a human guide, especially in a new terrain. This research reports the design and fabrication process of an intelligent walking staff (iWalk) specially designed for the visually disabled individuals to argument their loss of sight, improve and ease their navigation. iWalk was designed around water and ultrasonic sensors to detect obstacles and water ahead. iWalk also has a wireless RF remote control buzzer for localization and detection in case it gets misplaced. The proposed system operability and efficiency was adequately tested using physical dataset composed of randomized locations with random obstacles and water. The proposed algorithm achieves an overall efficiency of 90% detection rate for water and ultrasonic sensor and 85.75% for the RF wireless remote control.</p>

Information technologies have become necessary in the area of the health sector, with the new trends that are emerging, this work aims to develop a prototype of a smart cane to improve travel, allowing to avoid obstacles that obstruct the path of visually impaired people. The methodology used was traditional through the stages of analysis, planning, design, development, testing and implementation, for the development of this prototype the Arduino IDE software was used, using as controller an ARDUINO ONE, for the control of distances, it was used HC-04 ultrasonic sensors, transmitting signals through the vibrating motor and a buzzer that emits a different sound depending on the programming of the ultrasonic sensors. All these connections were linked to an experimental table called Protoboard, which are directed to the ARDUINO ONE board. The final product allowed to have a cane that was tested with, people with visual weakness, the functionality was measured with a questionnaire that evaluated the mobility function and the results were greater than 80% of acceptance

This hardware tool is designed for assistance and training for visually impaired people to identify the surrounding colored objects. Several researches are conducted all over the world to design advanced, reliable tool and techniques to support sightless individuals. This paper describes designing of a handheld device to assist visually impaired people for color identification via generated speech. Vision is one of the five senses which is essential for a human being to survive independently. All individuals acquire the external information through the visual coding entering into the eye. The light rays penetrate and stimulate vision receptors to execute the processing of image formation. In response, the brain is able to identify the object. Unfortunately, any accidents or visual disorders with age can restrict the ability to sight the external environment. A visually impaired person can identify the texture, shape and size of an object by touching. But the sense of touch does not permit color identification. This proposed wearable tool, aid mainly focuses on individuals who are unable to observe colors due to visual disorder. A hardware device is presented which generates the speech for color detection. In this proposed work RGB sensor is used to capture the color information of the entity. An Arduino UNO card is programmed using Arduino software 1.6.3 to enhance the signal. It generates a clear audible speech for the specific color of the object. The benefit of this device is low power battery operated, portable, safe and easy to handle.
