Yeah so... For me the first 4 variables can't be char, but have to be byte, or else i get errors, and then nothing gets displayed in the serial monitor

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?

[@techathome]

You can use 650rpm motor, but the motor should be able to provide good torque for better force feedback.

Row and column pins connections might be wrong. Recheck..

[@techathome]

Thank you

[@IOTgeek]

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. 😢

[@IOTgeek]

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.😢

[@techathome]

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.

[@IOTgeek]

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 ❤
