    Read the datasheet. The third line says it will work at 3 volts.

    Connect V- to ground and you are good to go!

    Indeed, the LM324 datasheet says that can be supplied with voltage from 3V, but in practice we found, depending on the application, operation more or less defective.
    For this reason I recommend you buy operational amplifiers designed to operate at 3 ... 5V, such as MCP600X series from Microchip.
