Hi, I'm new to arduino etc and I am working with an MCP23008. I'm confident I have it connected to the arduino correctly and I have the I2C address using a I2C scanner sketch.
All I want to know is how to set the pins on the MCP23008 high or low, like I would on the other arduino pins. I've read the datasheet but its a bit beyond me. I'm guessing Wire.send(something)??
