I have a problem, with the following.
DF Robot LCD Keypad Shield
and a Microchip " CD74HC14E
the projekt is : measure Hz and print it on the LCD display.
Is is all running with a normal LCD display.
But I have a pin problem with the new lcd display. Because it is a shield, I can’t decide the pin connection myself. and the library i’m using for the Hz mesurement is using one of the same pins, and I can’t figure out how to change this.
The lcd display is using pin : lcd(8, 9, 4, 5, 6, 7);
and the Microchip input using pin 5 according to the library.
Arduinno Board :Arduino Uno
Input Pin : 5
Pins Unusable with analogWrite() : 3, 9, 10, 11
can somebody please give me a clue ? how to change it to another pin.
