Have anyone built a stitch regulator using A9800 as optical sensor and NRF24 as wireless transmitter to replace sewing machine motor speed control paddle?
With that presentation You will likely wait forever.
If You read and use the topic How to get the best out of this forum - Using Arduino / Project Guidance - Arduino Forum You will more likely get replies. Helpers are able to read technical information regarding anything.
All my sewing machines have a tension spring and a friction knob built-in to regulate the stitches. Speed comes from stepping on the gas pedal.
How far away is the one thing with an NRF24 from the other thing with an NRF24?
Get the project functioning with wires. NRF24, unless you've worked with it successfully, seems to be an unnecessary complication to what shoukd be a simple enough project.
About which you could say more, in general and in detail.

So does my car. We are not clairvoyant and cannot see, touch, feel, etc your project and have no background information. I suggest you connect the purple wire to the pink wire next to the orange wire. Not very useful but falls within the realm of the data you have given us.
No I have not built a stitch regulator using a A9800 sensor and a NRF24. Post an annotated schematic showing how you plan on connecting this and also post your preliminary none working code. Follow the guidelines and use code tags.
Yes, you are correct. I do not need the NRF 24. Direct wiring is very doable. I read a project in Hackaday. I try to do the project myself but with limited knownledge . The commercial stitch regulator is available but costs over $1,200.00. They use two optical sensors mounted on a stationary plate and sensing the speed of fabric travel on top of them to generate signal to control the speed of sewing motor. As the movement of X and Y value, Z directly represent the ratio value to the stitch lenght, e.g. the fabric moved in 1 inch/sec on top of the sensors, the sewing head (set to 10 stiches per inch (SPI) will stitch 10 times on the fabric, if the fabric moved in 2" per second speed on top of the sensors the sewing head stitched 20 times - the stitches per inch is contant on the fabric.
It is the function of Stich Regulator. The output of the the control is 5 VdC to replace the foot pedal which connects to the sewing machine pedal port. The foot pedal is a variable resistor.
