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.
