Hi to all
I am new to electronics and I am playing with arduino the last few days. I bought a flexiforce sensor but in order for it to work properly tha datasheet says that I need extra circuitry that require -5volts dc to work with MCP6001 opamp.

Can you propose a circuit or an ic chip on how to get the -5v from tha 5v supply that I can get from arduino?

thank you

Harry
