Please make a video for how to make big servo using wiper motor and control it with flysky transmitter
hey i have a question, in the force feedback steering wheel, in the video you use a 1500rpm motor but then used pulley to reduce the rpm to 650rpm, couldn’t i just take a 650rpm motor?
You can use 650rpm motor, but the motor should be able to provide good torque for better force feedback.

Hi plz make video on wet dry segregation video
I am pressing some button it is showing other
for example i am pressing 2 but it is coming C
Row and column pins connections might be wrong. Recheck..
Op bro nice
Thank you
always a 1 in Serial Monitor, what should I do ? Even if I disconnect the keypad, and open serial monitor it shows 1 only. Please help🥲. Same result with both nano and uno boards. 😢
I did exactly same the way you showed in this tutorial. Used your codes, your defined library, pin connections all same still getting same issue.😢
It is showing 1 every time which means Arduino is not getting any input from keypad.
The row, column pins in the code and pin connections done might be not matching. Check once.
Thank you very much, sir. I found the mistake in my keypad connections, I forgot to mention earlier that I have been using custom made 4x4 keypad ( thought a bit before buying the keypad you are using, and made my own one) . So found soldering problem in the keypad. Thanks for your help. Love from odisha ❤
