How to find resistance of a resistor without multimeter using color code || Arduino || IOT || Tech

This video explains how you could use color codes to find the resistance of resistors.
You don't need a multimeter to find the resistance of a resistor just checkout the table in the video and start practicing.
with a 4-band color code, you just write down the numbers associated with the first two bands e.g 47 after that just write down the multiple codes and multiply it by the initial value when you are done you will have your resistance in Ohm . e.g 47*100=47000
similarly, do the same for the 5-band color code just ad the 3rd band digit after the first two and then see the multiple and multiply it e.g 473*100=47300ohm
The last band is always the tolerance band it tells you about the positive or negative variations in the resistance.
That is it please check the entire video I also have a complete playlist on IOT check that out as well.
