Dear Friend,
We have good experience in embedded software and design, It is not only our job but passion. We have worked on from basic hardware to quad-copters. Also have lot of happy and overwhelmed clients, we try to deliver more than expected.
We can do this project and can recommend suitable and cheap hardware for it. We are interested to discuss the project further. At end we will provide code, video demonstration and wiring diagram. Consider us :)
Thanks & Have a good day. Any queries and if u want to see more of our work, Please feel free to ask.
