testing on breadboard, for now a regular LCD is working. For the switching I've found how it works and already make loops on/off, but when I memorize them even when programming having 3 loops, it only glows one led. something wrong or i didn't understand yet how it works? Is it possible to supply a simple user guide?
Normal LCD working! So far trying to figure wich pins is the input output and mode switch!
Just found this and in fact it was what I'm looking for to make a few loops for switching guitar effects. Is there anyway to use a regular LCD since Arduino Mega has lot's of input/output instead the I2C LCD? If so, in which pins is the LCD connected? because in the schematic it did't show!
