Design and Implementation of an Improved Automatic DC Motor Speed Control Systems Using Microcontroller

Energy wastage is one of the major challenges that is facing the world now as there is

insufficient supply of energy and the little ones supplied was not appropriately used. This

energy wastage has made many researchers to engage more on the research to stop this

energy waste as a result of inappropriate allocation of energy to some devices even when

they don’t need it. This research work was able to design and implement an improved

automated DC Motor speed controller system using microcontroller successfully. The

software used for this research work were Fritzing software and Arduino Nano. This project

was able to improve on the working system of the DC Motors and energy was automatically

and successfully saved. The system runs entirely on Bluetooth technology which consumes

less power than other devices. The Android application is user-friendly with enhanced

Wireless communication. This design was successfully developed and implemented with 80%

accuracy. The design was able to work effectively by increasing the cutting speed when the

softness of the material decreases and as the cutting tool material becomes stronger, the

cutting speed increases. This showed that the design is effectively and efficiently developed

with less energy/power consumption which is the earnest desire of an Engineer as it reduces

cost.
