Use a 4-modes debounced push button, a signal level spy and a convenient linear pot, on your breadboard or with a Grove cableDesigned by jdn in Switzerland
You cannot get these among the hundredth of cheap Grove modules. Also, in addition to the Grove connector, there is a 2.54mm strip compatible with your dear breadboard. SmartPush Debouncing a push ...Read More…
Debouncing a push button is easy. Toggle function is already more tricky for a beginner, and it takes instructions. The local microcontroller of the SmartPush do the work for you: it reads a DIL switch and apply the selected mode (same for both push button):
The Logic pen says if signal is LOW, HIGH or an an intermediate level. Spy module is an analogue device that shows if the logic zero is good red LED bright, logic one is good (no red, green LED bright). Variations of an analogue signal are easy to follow. Test with a pot. See http://www.didel.com/digrove/DgSpy.pdf
Smooth, easy to move with one finger, very fast change is possible. A 50 Ohm resistor limit the current and a solder jumper decides which pin gets the signal. See http://www.didel.com/digrove/DgPotLin.pdf
