Digital Potentiometer (X9C103S) Introduction and Demo with Arduino

Introduction of X9C103S digital potentiometer.
Explain the structure and operation of X9C103S, and how to control the resistance of this digital potentiometer.
Also shown in this video, is a demo of X9C103S controlled by Arduino nano, swiping up and down the wiper, and storing the current wiper position.
A useful tip (or a bug?) while storing the wiper position is also revealed!!

Demo codes and configuration can be downloaded from following link:

Was helpful for me interfacing X9C103S 👍

Thank you very much for this video and the comprehensive information about this digital potentiometer. In my project, I will use it to replace a mechanical potentiometer that controls the speed of a 12V DC blower motor (it's a car heating blower motor) with a digital potentiometer X9C104 that will be automatically adjusted from an Arduino Uno. This video helped me a lot providing all the necessary information that I needed and saved me from searching different sources of information and data to do the task.

Thank you this is exactly what I'm looking for for my next project!!

[АнтонАнтонов-ьщн]

Very informative video. Thank you very much! Now I know about this one additional tap point at start up.

Hello from India...Thank you very much for this easy to understand and very helpful video.... Looking forward for more electronics and arduino videos...subscribed.

Dear sir
Extremely thankful to you sir for this nice information about potentiometer..i was in search of this for a pretty long time.I m now hopeful that I may built volume control for a radio with your guidance using RF.remote controller.
Once again thank you very much sir
Regards

Hi sir, can i ask? I want use digital potensiometer without using button. If it possible? Using only command in arduino? And how to program without button

[sumankar]

Please tell us can we supply 0 to 5V by this with Arduino programming

[Cuaks_lemon]

Can i using without Arduino only 2 button to control the chip?

[StressBurner-]

Can we increase 20 ohm step using this from 0 ro 10k?

[brucepsyduck]

Hi, in INC and U/D only works if we use 0 and 1 (high/low) ? or we can use anything value in the scale of 0 to 255(pwm)?

[rebintalite]

good day😊 can I use it to replace the analog potentiometer of a LED lamp dimmer and control the digital potentiometer by Arduino uno?

[typingcat]

So..., why is the restored value 100 higher than the stored value, is it some sort of bug?

[junaidarshad]

Hello, can I use it to vary the feedback resistance of an operational amplifier to vary the gain?

[aravindpadmasali]

Dear sir,
can we use this as a volume control for audio amplifier, please share the wiring diagram of how to connect volume up and down switches

[georgesoare]

Hy, i have a question, can you tell me how can i connect a loudspeaker digital volume control to a hall sensor (from finger throttle's ebike ) in order to be able to control volume. Thank you in advance for your answer

[karartikararti]

Hi sir, do we need to combine the two codes that you have added to your drive? And can I use these codes to connect it to an Rc controller? My goal is to change the voltage value remotely via an Rc controller.

[armincal]

Are these used to increase and decrease sound volume in phones? I always wondered how the resistance of a circuit can be changed programmatically such as in Windows and android

[Electronics-nw]

I made this but resistance not vary up to full 10k it vary hoti 5.7k. what is the reason

[PnyouT]

What happens when we press that switch once rather than continuosly pressing
