    Nothing obvious is wrong with the code, except that there is far more of it than it needs to be. Gihan Lasita Gihan Lasita 2, 11 11 gold badges 46 46 silver badges 65 65 bronze badges. So you don't want to count pressiine, you want to move a number in the display. You get some serial output. Thanks for that info, really interesting. What is Serial. Learn more.

    Good morning, I am currently embarking on a project to control a heater using 2 push buttons, 1 to increase the heat and 1 to decrease the.And with U and D what do you want?

    Hi I have a sketch found in Arduino COOK BOOK page well he counts to , word after very slow. Now I'm working on for some time.But I knwo I have tested to put say a 9 from an int into a specifik element in the array and when I printed the array it was changed.

    I just followed a tutorial to make a push button count up from 0 to 9 on a seven segment display. I'm very new to arduino and after looking.Gihan Lasita Gihan Lasita 2, 11 11 gold badges 46 46 silver badges 65 65 bronze badges.

    Up Down Counter Circuit. Another circuit for learning to code Components and supplies 3 DIGIT. You can code 3 digits to the counter.I don't know what your purpose was, but you need to use if statement.

    Just to recap: want to count from low-high and high-low without the delay of using none-sequential pins. NOTE: I have the program running right.I think the reason that it appears to only run once is that byte is an unsigned type.

    The button and debounce thing is from the Arduino examples with of course the necessary changes. And yes I know the button things can be made.Only because it is.

    This works but is there way to do this without if conditions inside the loops? c loops for-loop arduino nested-loops · Share.The difference being this project counted up then when it reached the 4th output it returned to the first one after you press the button.

    rutex.online › Circuits › Arduino.When the unit is powered up i want nothing to happen all Outputs Low and PWM at 0 I have previosly created a project in which i switched audio sources using a push button and an internal counter either sending outputs high or low dependant on the value of the internal counter using the if function so i thought this would be a good starting point.

    For char it just assume that it is already ascii code and just prints it straight.

    I have 5 LED's which i would like to turn on in a bar graph style to indicate the level at which the heater is operating.

    This will also involve understanding millis.

    You can assign a char to an int.

    This could be due to teh fact in my description of my circuit i labeled all outputs as D4.

    An easy way to convert a single-digit integer to a character is to add 48 or even to add '0' which more clearly indicates your purpose.

    You get some serial output.

    But the int char thing messes it all up so I have to rethink it all due to that, but at least now I know what was wrong, but I might even take a look at that function that was mentioned, if it exists in Arduino that is.
