The analog pins are not working on my custom build arduino.
Using this tutorial [Link] I built the arduino on a solder breadboard.
The project is to create a reprogrammable controller for really any future projects.
The LCD (20x4) works just fine until I add analogRead() functions.
Once the analogRead() is added to the code the lcd does not display ANYTHING.
The code works on my pre-built arduino, but of course... Not on my custom built arduino.
There is nothing added beyond the tutorial, the thing that the tutorial has that mine does not is the usb-to-serial device. I just use my arduino to reprogram the IC. (Yes eventually I will setup the serial device)
Yup, correct pin. I have checked the pin-mapping [Link].
Is there some sort of capacitor, resistor, flux capacitor I am missing?
I have been told to try a .1uF capacitor for the VCC as a bypass capacitor but that didn't seem to work. (also tried AVCC)
EDIT: Also even if it was the wrong pin, the "welcome" screen if you will; should display.
If you look at the sketch it should display an asterisk box with "Wireless V 0.1" on the screen.
Unless of course you meant the wrong pins for the LCD, but that wouldn't make sense since it works with out the AnalogRead().
@Halley: But would that stop the original splash screen? I don't think it would.. :-?
@Trialex: Yeah I am really starting to think it might be just be the wiring.
Even though I have gone over it a tons of times.
I am going to do more debugging today and hopefully get to the bottom of this.
Do you have any suggestion as to were to start for debugging since the LCD works with out analogRead, wouldn't it be something with the analog features?
Maybe I can get a clear picture, but I doubt it. I have an 8MP camera, but it doesn't give me clear pictures for some reason.
I could try some things later.
