- problem checking bacground on this;Compatible with HD44780 1602 16x2 Serial LCD White Character Blue Backlight Display Board 3.3V 5V Compatible with Arduino
Hellol I have pins for this; apologies for subseqquent bold; bold option is not responsive.
Compatible with HD44780 1602 16x2 Serial LCD White Character Blue Backlight Display Board 3.3V 5V , Using Arduino Uno.
15 and 16 connected; 16 to gnd via a 220ohm resistor and 16 to 5v. Mtest meter reads 5v but the screen is not illuminating.
It had previously been functional. Is any other test possible or is i that the module has become faulty?
Thanks
Martyn
PS: mentor adjusted to remove bold text.
It wasn’t bold tagged it was bracketed by [ head ] tags and that’s why it didn't unbold.
