Each time the input pin goes from LOW to HIGH (e.g. because of a push-button press), the output pin is toggled from LOW to HIGH or HIGH to LOW. There's a minimum delay between toggles to debounce thecircuit(i.e. to ignore noise). The circuit: - LED attached from pin 13 to gr...

Push buttons come in different sizes and a small button will have different bounce characteristics to a larger one. The solution The solution to make the Arduino toggle switch work is...Debouncing.There's are many ways to debounce a switch which are described in the easy switch debounce page...
DailyStruggleButton is yet another Arduino library to debounce button (push tactile switch) and manage its events. Events supported include pressing, releasing, holding down, long pressing (hold button for x time) and multi-hitting (hit button x times in y time). For simplicity, there is only...
