Thermoelectric portable mini fridge using Arduino Uno temperature control

A study has been developed on mini fridge products where using a thermoelectric system of peltier which produces cold and heat for learning and 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 fridge as well as adding convenience for consumers to use the fridge well and comfortably. This is in line with the needs of users who need the convenience of any fridge 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 fridge 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 thermoelectric, also often called as 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 pin 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.
