    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

    Also the 7661, MAX660 or MAX860, there are several with similar functions. Some of the Maxim ones are good for 50mA or more.
