#9 [CC] Digital Tachometer DT-2234C+ - Review

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
