Pi controlling Arduino system

[OhNoItsMrBill]

I have been commissioned by a friend to provide some automation to a device for research. Currently there there is a bunch of manual switches that switch relays. There are additional monitoring of the box as well that is desired, example several temperature, current, voltage... This is pretty easy to do for me using a Arduino, however the lead wants to us a Pi as the main interface so that a larger simple program interface can be developed and projected on a TV. I have not played with the Pi at all, so I am on a steep learning curve.

Please recommend a Arduino like system that I can do control with from the Pi or recommend the proper method for I2C or Serial to pass information to/from the Arduino/Pi

Using an Arduino as a data acquisition front-end is certainly achievable. But the Pi is a capable of that as well. The Pi has GPIO pins for digital I/O. We have a variety of breakout boards that are compatible with the Pi, including basic ADCs as well as sensors.

You might want to start with some of the lessons in the Adafruit Learning System to get up to speed with the Pi.

I'm using a Teensy 3.0 and an RPi for networked temperture monitoring and control. You can see it at my website http://www.teensypi.com
