A detector in the middle of a circle made of 12 flash lights. please see attached. the detector got 180 photo detectors connected to Arduino. the lights 1-12 flashing in CW at rate of 5ms. the detectors are synchronized with the flashing lights(knowing when flashing is). Given the diameter of the circle in white. Write a program to calculate the position of the detector in x,y relative to flash #1.

Dear Sir, I can demonstrate a prototype with high speed pulse detection. The transmitter end needs a pattern. I have implemented such a thing for industrial purpose, have the necessary equipments too. I am a professional. Is this project still open . I have got some questions also.

Hello. I can make this project for you. There is some moments i need to clarify: 1) You need multiplexing cirquit to connect 180 photodiodes to Arduino. Do you need a PCB design for this board or already have it? I have experience of connecting up to 250 sensors to Arduino and can propose acceptable solution for this. 2) How the synchronization with LEDs will be organized? Some wire/cable will be used? Or something wireless is necessary? For this task another (smaller) multiplexor board is necessary. Alo, as I understand, the distance between device and sensors require to use enough powerfull LEDs, so commutation cirquit is necessary. 3) Multiplexing cirquit is enough slow solution, and analog measurement of 250 sensors will be take enough long time (up to several seconds). How fast calculation shall be? Also, as I understand, the period of 5 ms is choosen to remove visible "blinking". But signal will be enough weak, and mixed with 50Hz EMI. What you think about using of IR LEDs and larger period of measurement. Also some optimized algorythm of blinking sequense can be involved. In any case I will have to make the prototyping PCB's for this project for debugging. If you want - I can send it to you. Cost of components and delivery, about 60-100$, will be added. With best regards Maxim

Hello! Very interesting project. But for this project realization I need additional information: 1. In what way 180 photo detectors will be connected to the arduino? What the type of photo detectors, type of their output signals? It is important. 2. After long time of working the synchronization may fails even if quartz stabilization will be used in circuit. How long a time of system working after the synchronization start? Hours, days, weeks? In any case I will create a quality arduino programm for your project. I have a great experience in arduino programming and electronics. My bit has a minimal price becouse I need a positive feedback and review. Rating for me has a higher priority than money now. If you have any question tell me. Thanks.

Photo detector should should have specific resolution and also timing sequence should be in right manner. I can do this in simulation software PROTEUS to feel it real. Also I can make real word gadget to fulfill your requirement.

Hello, I understand that the lights have to be flashed sequentially every 5ms in CW and the intensity of the light of each flash to be measured from the photo detectors. The the position of the detector will be calculated based on the 12 different light intensities measured. I am suitable for the job since I am expert in electronics and know how to program microcontrollers. I am going to finish the job in two days upon agreement of the final details of the project. Do not hesitate to contact me for a more detailed discussion. Thank you for making the right choice.
