Prosthetic is an artificial device that replaces a missing body part that may be lost due to trauma, disease and congenital conditions. It is intended to restore the function of the missing body part. The prosthetic that will be developed in this project is prosthetic hand. This prosthetic hand will have the robotic part applied to it to help the handicap person to do their daily activities just as how they used to when they still have their hand. The problem with the current prosthetic hand is that it does not function well and does not assist the patient to do daily chores. Hence, this robotic prosthetic hand is developed to overcome the problem. The objectives of this project are to develop a prototype of the prosthetic hand using 3D printer, to determine placement of actuator on the prosthetic hand, to help assist the handicap person in doing daily activities and to control the movement of the prosthetic hand by using EMG. The prosthetic hand will be design with Solid Work software and then print with a 3D printer. Then, three EMG electrodes are placed on the patient‟s forearm to detect the signal. The signal will then be interpret by the Arduino microcontroller as to which part of the hand will move whether it is the fingers or elbow. This prosthetic hand can be attached to the patient‟s bicep. At the end of this project, this prosthetic hand can hold or release for the fingers part and move the elbow up and down.

The development of this project will bring out an automated recycle bin which able to sort metal and nonmetal item that can be monitor through IOT. The ideas of this project came out from the problem statement which Recyclable materials end up mistakenly disposed to general landfill. Even though the awareness campaign is already made by government, mix recycle trash problem still occurs. Furthermore, workers affiliate with trash is more likely to be infected. In order to reduce these problems, an automated recycle bin which sort metal and nonmetal item is created with additional function of trash level monitoring system through IOT. This project will implement the usage of Arduino, servo motor, ultrasonic, IR and metal sensor. With the design of this machine, may it help those who involve in waste management and reduce the company cost in hiring manpower to separate the recycle waste and monitoring the waste which result to cleaning or trash collection more efficient. With a further modification, may it sort more recycle item

Traditionally, pollution measurements are performed using expensive equipment at fixed locations or dedicated mobile equipment laboratories. The automatic air quality monitoring system using Arduino can save cost and easy to access. The project that we have undertaken has helped us gain a better perspective on various aspects related to our course of study as well as practical knowledge of electronic equipment and communication. Moreover, the project of air quality monitoring system has achieved to monitor and prevent the effect of high temperature and dusty air to the child and human just like the objective of the project needed. The project can detect the temperature and dust density and besides that it will send alert to the user when detecting the air quality is unhealthy. Furthermore, a project is design and develop air quality monitoring system using Arduino Mega which is to enhance safety affect such that even the minor eye irritation can make the user to lose his concentration and lead to serious accidents. Where the dust sensor and temperature able to detect hazy day that triggers buzzer to alert user to decrease the outdoor activities. Air quality is monitor for whole day at Ulu Pauh Putra by using this device and the data is recorded and make into a graph. The average dust density is 78.22ug/m3 and the range of dust density levels are about 68.07ug/m3 to 84.87ug/m3. By comparing the result to API reading show that air quality is moderate pollution that does not pose any bad effect on health. The testing of project was done for whole day is to verify the accuracy of the data. Moreover, it can help to avoid errors occur in the project. Focusing on the device produced, it detects high temperature and sense the dusty air immediately. Once the sensitivity is high, the buzzer module will active to alert user.

A study has been developed on water cooling products where using a thermoelectric system of peltier which produces cold and heat for learning and also it needs for the Final Year Project, in Diploma of Manufacturing Engineering. This study is aimed at improving the use of the system in the water cooling as well as adding convenience for consumers to use the water cooler well and comfortably. This is in line with the needs of users who need the convenience of any water cooling and easy to use in line with the development of technology developed through existing products in the market. This study focuses on how to develop a water-cooled product system so that this product can provide the user with the convenience. To develop the system, thermoelectric peltier and arduino uno are used to provide improvements to existing products. The peltier thermoelectric, also often called the Peltier coolant that utilizes the Peltier effect when passed through the current, this device will transfer heat from one side to the other, typically producing a heat difference of about 40° C - 70° C. Arduino is a microcontroller based ATmega328 board. Arduino has 14 input pin/ output which 6 pins can be used as PWM output, 6 analog input, 16 MHz crystal oscillator, USB connection, power jack and reset button. Arduino is capable of supporting microcontroller; can be connected to a computer using USB. Arduino cable is also programmed using a special software called ARDUINO GENUINO which program the cooling temperature of the peltier thermoelectric. In conclusion, this system has been successful in helping to increase knowledge and convenience to consumers and will probably be one of the obligatory products in every home in the future.

Main objective of this research is to study the performance of thermoelectric cooler for application in cooling system of injection molding machine in order to improve the cooling system and cooling cycle time of injection molding machine nowadays. The project is done by using thermoelectric devices, water block, Arduino UNO, relay module and water pump. With the testing and experiment rig carried out, it is discovered that the thermoelectric devices could also being applied into the injection molding cooling system. The testing was carried out by clamping thermoelectric devices with two water block and regulating water in both water block. Arduino UNO microcontroller and relay module was used to control the temperature sensors and water pumps in the hot-side and cool-side of the water block. Both temperature of water is being measured and recorded by the temperature sensors and Arduino software. Hence, the data and graph of result could be gained while the experiment is being carried out. From the result of experiment, the thermoelectric devices can be said as an effective cooling system as long as the heat produced at the hot side of the thermoelectric could be removed all the time. However, for the real environment injection molding machine applying, this system will need modification and adjustment on design of the cooling system.
