Hi everyone. As it's a fact that digital pins of Arduino do not provide analog output, but switches so fast that we assume it's giving output between 0 & 255. (true?)
- In that case would it be good enough to use pwm voltages for lcd's backlight?
- I've LMB162abc & following a tutorial hacktronics I've made it work but I've used 4 bits only (text + both rows are working), what are the other 4 bits for? As it is an eight bit lcd then there might be some difference.
