Hello. • This content was produced on the 9th TECH DIY channel. • When you try to make with various motors, you need to know the rotational speed (RPM) of the motor. • I bought a digital tachometer made in China on Aliexpress. • The price was 8.15$ including shipping and it shipped in about 2 weeks. • Since it is a measuring instrument that has already been used for other content production, it is a good review content. • I wanted to make it. • Since it is not possible to measure the accuracy simply by measuring the rotation speed of the motor, it is possible to use an oscilloscope. • I used the PWM signal generation function in the logic analyzer to check the error. • Hope it helps viewers buy their products, and if the content helps • Good subscribe please. • Thank you for watching. • ㆍTECH DIY: / @freewarekr
