Resistor Ladder For Button at Joel Lennon blog

Resistor Ladder For Button. Here is a short sketch i used to test the circuit and show the voltage reading for. You can calculate the voltage reading for each button by considering that button as pressed, removing the parts of the voltage latter circuit that are open and applying ohm's law. Each pin is configured to register a different voltage. A resistor ladder is a brilliant but super simple way to attach multiple buttons to a single analog to digital converter (adc) pin on an arduino. This came about where i needed to fit more than a handful of buttons onto a single analog pin and quickly realised it. The problems start when the switches. Pressing one of the buttons on our circuit changes the output to the analogue port from 5v to a lower one determined by the number of resistors (r1 to r4) in series before the button, as you go down the ladder the output voltage to the pin increases. To press multiple buttons at once, a resistor ladder wont work, connect each button to its own digital pin and use blinkwithoutdelay () to make pressing 2 buttons at once. Really critical is the button connection. A resistor ladder is a method for detecting multiple buttons on a single analog pin.
