IOT Hardware components can include low-power boards; single-board processors like the Arduino Uno and Node MCU. An Arduino Uno is a microcontroller motherboard. A microcontroller is a simple computer that can run one program at a time, over and over again and it is very easy to use. But the structure of Arduino is its disadvantage, the easy to use hardware/software of Arduino unable a person to learn the basics of many things likes Serial communication, ADC, I2C and Arduino libraries are not very efficient in certain parts and waste RAM and CPU cycles. NodeMCU is a development board featuring the popular ESP8266 WiFi chip. Its obvious advantage over the Arduino is that it can readily connect to the Internet via WiFi. However, the ESP8266 breakout board has limited pins although the chip itself has a lot of output ports. The NodeMCU solves this problem by featuring 10 GPIO pins each capable of using PWM, I2C and 1-wire interface.This paper provides Internet of Things oriented comparison of Arduino Uno and Node MCU boards with suitable selection of the hardware development platforms that are capable enough to improve the understanding of technology and also summarizes various capabilities of available hardware development platforms for IoT.
