ARD-620 Arcade Style Pushbutton Breakout Board
US$4.61
This is a simple breakout board that features five pushbuttons. You can program your code to specific functions when the buttons are pressed. This board is a perfect example of how to design a circuit using only one analog pin from your microcontroller! Depending on which push button you press it will vary the voltage begin returned back to the microcontroller! If you are looking for a simple board that doesn’t use multiple digital pins and is easy to use, this board is a genius little trick to save those precious digital pins. Note: The pushbuttons come with a yellow cap, you can purchase our pushbutton kit that comes with various colored caps if you choose to decorate the board. When no buttons are pressed analogRead will indicate the full voltage 1023. SW1 will be 0, SW2 will be 30, SW3 will be 86, SW4 will be 164 and SW5 will be 348.
