Hello,
I'm Gayden Yuki, a 3rd year computer engineering student. I do have experience with arduino and I think that's what you need.
Regarding your project, I have the photon and I have worked on it before and I have the required arduino knowledge. I never dealt with azure, mag switch or PIR before but it's not hard I just need some information from you on what I send and receive.
I have worked on 4 projects that involve hardware the first is MV3, a health monitoring wristband that measures health conditions, sends data to a mobile app and does data visualization to these data and it's currently in the production phase. The second is Air Intelligent, an intelligent airport platform that eliminates the queues problem at airports providing a new traveling experience to the customers but unfortunately it's not implemented yet because we didn't find an investor. The third project I worked on is called Cartist; a smart shopping cart that lets customers put their stuff in the cart and then pay directly through their phone without the need of staying in any queues to pay.
The last project I worked on was controlling a DC Motor using PC. So basically you open a program, specify the distance, the speed and direction of movement, and the PC will send those values to a photon connected to an arduino which sends those values to the aduino to control the DC Motor.
I hope that the experience I have is enough to be hired for this job. And the cost is of course negotiable. Thank you.
