After getting my Electric Imp basics right I’m now moving on to a bit more complicated project. I’ve picked the London Bus Time Tracker as my next project. I did not pay much attention to the LCD voltage suggestion and picked a 5V LCD from Amazon. Also picked an I2C backpack and a bi-directional level shifter. I am looking for help on the following things:
- Will this hardware combination work (LCD + backpack + level shifter)?
- If yes, then can someone please help me with the wiring between I2C backpack <-> level shifter <-> April board?
- The I2C backpack is based on PCF8574. Can I use the code from here?
Thanks!
