Raspberry Pi Forums

Hello everybody!

I am sory for probably a stupid question, but I am just going to buy raspberry pi, and some starter kit stuff to start working with it. I found, as for me , a really good choice of starter kit on ebay store (http://www.ebay.de/itm/37-in-1-Sensor-M ... 1320343441), but it is designed for arduino. So my question is, would contents of this starter kit be compatible with raspberry pi? It seems for me to be compatible, but I want to clarify it, before making a purchase.

Thank you in advance for your help!

Short answer: maybe, maybe not. The Arduino is 5 volt tolerant, the Pi is not. Some of those sensors may use 5V logic levels, which could damage the Pi without additional circuitry (level converters, potential dividers, etc.) You'd need to check out the datasheets of each sensor to see if it can work with the Pi. I imagine mostly they would, but no guarantees.

You would need a logical level converter (3.3V/5V) - then it might work, or a 5V GPIO expansion board (I2C, but it doesn't give analog GPIO for some of the boards) or USB connectable microcontroller board that uses 5V - Arduino, PyMCU and alike. Then it would work. Things like the relay board would need the microcontroller to be connected to a fully powered USB.
