This course will teach you how to make your own Arduino Digital Ohmmeter at home using Few electronic components and LCD Display. This Guide will take you in a step by step manner to know what each component is, why we use it, and what it does and how to wire it up, starting with the basics of Arduino and ending with displaying unknown resistance on LCD display and discussing Analog to Digital Conversion using Arduino. You will know what is the actual working principle of Arduino Digital Ohmmeter, what is need to be coded and how to interface – wire -and code all parts correctly so that you can make Arduino Digital Ohmmeter using different scenarios and implement the knowledge that you will get in this course in different project ideas. After this course, you will be able to make your homemade very own Arduino Digital Ohmmeter and the choice is yours to use it and apply it with any application that comes in your mind.
