Using a TSL2561 with a LCD shield.

by tron001 on Sun Jun 02, 2013 5:40 pm

I have a TSL2561 #439 which I intended to use with a 16x2 LCD shield #772 on a Arduino UNO.
The TSL2561 is a 3.3v device and the LCD is a 5v device. According to the specs these two
devices can't be on the I2c pins at the same time.

Is there any way to get these three to work together? Or do I need to find a 3.3v LCD.

Thanks.

You want one of our 4-channel I2C-safe Bi-directional Logic Level Converters:

Thanks.
That looks like exactly what I need. I don't know how I managed to overlook it.
