Now that your setup has been completed, move into the main loop of your code. When your button is not pressed, the internal pull-up resistor connects to 5 volts. This causes the Arduino to report "1" or HIGH. When the button is pressed, the Arduino pin is pulled to ground, causing ...
For the full Arduino code, you can headhere Summary That’s all for today on pull-up resistors. I hope with today’s blog, you get a deeper understanding of what is a pull-up resistor, the differences between pull-up and pull-down, alongside interfacing with an Arduino board! Remember,...

If you run this code and open the Serial Plotter, you’ll see that the default value is 1 (HIGH). When you press the button the state directly goes to 0 (LOW) and comes back to HIGH when you release the button. Well now it’s much better. Problem solved!
My rule of thumb: any Arduino project can have one clever hack that goes outside the normal bounds, but more than that will land you in a world of hurt. 2013-06-10 Michele Hi, i used your code and it worked prefectly, very good job. I don’t have so much experience about timers...

3. The Gcode file is saved in the memory card, arduino reads the file from the card, and parses the position coordinates into the action of the stepper motor, and draws the rope to drive the pen to draw. (The WallDraw.ino program in the program package can perform this step) (Note...
That this actually enables the pull-up resistor on most Arduinos is a quirk of the AVR chip, but you taught me that it's not idiomatic Arduino code and that there is a better way. Good to know! You got my vote for teaching me something I should have known! :) 1 reply JeremyS...
