I want to print the % sign on my LCD. Uses the lcd.print(“ C”); gives me two characters of four horizontal lines. Finding the binary values and converting these and using the lcd.print((char)37); and uploading this also gives me the same horizontal bars. Neither method displays the % I am after.
Any advice on how to fix this and making the readout to no decimal places?
Yeah but I think because of those 2 sets of four horizontal bars on the screen I just couldn't see it. When I got rid of the extra 2 decimal places the 2 sets of bars are still there but now I can see the % sign. Any idea how to get rid of the bars?
