#172740 - re-think code Responding to: Joel Ward's previous message |
Hi, Joel,
5...6 millisec is a lot of time. Task is fully for software , yes- with little help from microcontroller's hardware - connect sensor to IRQ pin, use additional timer if debouncing is needed. In hardware - connect capacitor to sensing pin - reed relay will discharge this capacitor fast trough small resistor - 50 ohm , VCC will charge slowly-slowly trough some kiloohms. But this is really bad idea. regards |
