Hi,
I read your project description. The requirement is a SPI slave device with ambient sensor, gesture sensor and stepper motors connected to it.
I have done several Arduino projects in the past. I have used several sensors, actuators and user interfacing modules for those projects. (You can see my profile and portfolio).
Please let me know about components you have selected.
I will provide you,
1. List of required components
2. Instructions to set up the hardware
3. The software
4. Instructions for uploading the code
5. Instructions for testing and troubleshooting
6. Any additional information regarding the system
I can assure you I will complete this project successfully before deadline.
In you description you haven't provided much details. If you provide more details, then we can finalize project budget and deadline.
You can contact me for any clarification.
Kind regards,
-Akilan
