| Sep 12, 2013 at 8:18 | comment | added | James Cameron | The tutorial is also inconsistent with the datasheet. Perhaps you might talk to the supplier. I would. If only to get the tutorial fixed. ;-) | |
| Sep 12, 2013 at 8:15 | comment | added | Val Blant | Oh damn - now I see the note in the datasheet. I didn't notice it at first due to the inconsistency. I just saw the +5V in the table, and in the tutorial from the supplier, so I didn't read further! I think the mystery is solved. Thank you! | |
| Sep 12, 2013 at 8:14 | comment | added | James Cameron | The datasheet does mention a forward current of 100mA near the bottom of the same page. | |
| Sep 12, 2013 at 8:13 | comment | added | Val Blant | @PeterJ: How did you come up with 100mA value? Is that somewhere in the datasheet? | |
| Sep 12, 2013 at 8:09 | comment | added | James Cameron | However, the datasheet TC1602A-01T.pdf does have an Interface Pin Functions table on the same page which says 5V for the LED+ signal. The datasheet is inconsistent. | |

The data sheet clearly states :- NOTE: Do not connect +5V directly to the backlight terminals. This will ruin the backlight.

| Sep 12, 2013 at 8:03 | comment | added | PeterJ | In the second case the 4.2V would be the forward voltage drop of the LEDs so rather than use diodes you should have say used an 8R2 resistor for 100mA of current. | |
| Sep 12, 2013 at 8:01 | comment | added | JYelton | It's entirely possible you simply have a defective backlight. Also, is that a 5.25" disk drive sound in the background of the video? :) | |
