I installed a project that required the 'Wire', 'SoftwareSerial' and 'Adafruit_ADS1X15' libraries. Now when I do even the simplest of pushbutton turn LED on tasks it freezes the board until I release the button. Using both UNO R3 & Mega 2560 What could possibly cause this?

[image] newbcoder: What could possibly cause this? I'd take a wild guess and say "your code" :wink: but you didn't post it for anyone to see, so who knows? Perhaps a mis-use of delay().

It's not the code. I was just using a basic on/off program to test the boards... int ledPin = 13; // choose the pin for the LED int touchPad = 2; // Connect Touch sensor on Digital Pin 2 int inputPin = 3; // Connect sensor to input pin 3 Serial.begin(9600); void setup() { pinMode(ledPin, OUTPUT); …

[image] newbcoder: It's not the code. It's certainly not the code you posted, since it doesn't even compile.

One possible reason that it does not behave as expected is that Serial.begin() should be inside setup(). Not behind a PC to test.

When I fixed your uncompilable code by moving Serial.begin() it works for me. However, all my button boards are wired with the button from pin to ground and I therefore use input pullup in pinMode(). Then it shows 1's while the button is not pressed, and changes to 0 when pressed, as expected in my …

Sorry people, my bad, early morning, yes, I forgot to put a pull up resistor on the board.
