I'm building a water pump with a DC motor. I'll harm the Arduino board if I attach the motor straight to it. In order to prevent harming the board, I used the NPN transistor to control the motor's switching behavior in accordance with the instructions. Electric current can only flow in one direction through the diode. A negative voltage surge that happens when the power is switched off could harm the Arduino board or the transistor. I thus utilized a diode to guard against this harm.
The two wires that make up the soil moisture sensor are used to gauge how much water is present in the soil. These cables compute the resistance while still allowing current to flow through the ground.
Undoubtedly, there were challenges along the way. Initially, I encountered difficulties in getting the Arduino application on my laptop to recognize the designated port. However, I tenaciously persevered, exploring troubleshooting methods and seeking guidance to overcome these obstacles. Eventually, I successfully resolved the issue, allowing me to proceed and reach the desired stage of the project.
In addition to the technical knowledge gained, this endeavor also fostered a sense of personal growth and accomplishment. It cultivated my problem-solving skills, resilience, and adaptability in the face of setbacks. The project provided a platform for me to explore the fascinating intersection of technology and plant care, encouraging me to think innovatively and consider the potential applications of automation in various domains.
Overall, working on this project not only expanded my practical skills and knowledge but also instilled a sense of satisfaction in tackling complex challenges head-on. It reinforced my enthusiasm for exploring the possibilities presented by emerging technologies and their impact on our daily lives.
