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 have good command over arduino and sensors/peripherals interfacing. You want arduino to emulate the coin inside, can you explain it little more. We are interested to discuss it further and can do this task as per your satisfaction. Consider us :)
Any queries and if u want to see more of our work other than portfolio, Please feel free to ask.
Thanks & Have a good day.
