Help make button-sketch sleep.
-
I tried using the button-sketch unmodified to control a lightswitch (non-momentary) I just wanted the arduino to register when it was switched and have the controller send a command to light or turn off a lamp. All worked like it should but the battery (18650) only lasated a few days before dying. I guess that it does not sleep properly.

Or am I missing to understand how to connect the arduino? I connected the battery directly to the arduino and wanted it to wake up when for example the switch connected digital input 3 to ground.

I looked at the motion scetch when i did this:
Sleep on interupt is: gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME);
-
Ok I am not very good at this I usaly just try to copy the sketches as they are.
But if I use the motion sketch and connect a switch to GND and D3 it will wake up and report to the controller when switch has been activated. And if I connect the switch so either D3-GND or D4-GND is activated when flicking the switch it will also wake up report to controller and then sleep.

I think only D2 and D3 can handle interups and D2 is used by the radio.

No, it is currently not used by the library. We just keep it connected to D2 (in the guides) because we could eventually find a good use for it in the future.
Also, actually all digital pins on ATMega328 can be used to wake the MCU but only D2/D3 can trigger on RISING/FALLING. The rest support wake on CHANGE.
(Please correct me if I'm wrong here HW-guys)

@Cliff-Karlsson
There's a good example in the MySensors lib with sleep and two switches. https://github.com/mysensors/Arduino/blob/master/libraries/MySensors/examples/BinarySwitchSleepSensor/BinarySwitchSleepSensor.inoMy adaption of that one to my own need and with one swtich looked like this
#include <MySensor.h> #include <SPI.h> #define SKETCH_NAME "BinSwSleepBat" #define SKETCH_VERSION "1-2" #define CHILD_ID 0 #define BUTTON_PIN 3 // Arduino Digital I/O pin for button/reed switch. On Atmega328p (nano and pro mini) D2 and/or D3 are interrupt pins. MySensor mys; MyMessage msg(CHILD_ID, V_TRIPPED); // Change to V_LIGHT if you use S_LIGHT in presentation below int sentValue=2; void setup() { mys.begin(); pinMode(BUTTON_PIN, INPUT); // Setup the buttons digitalWrite(BUTTON_PIN, HIGH); // Activate internal pull-ups mys.sendSketchInfo(SKETCH_NAME, SKETCH_VERSION); mys.present(CHILD_ID, S_DOOR); } void loop() // Loop will iterate on changes on the BUTTON_PINs { mys.sleep(50); // Short delay to allow buttons to properly settle uint8_t val = digitalRead(BUTTON_PIN); if (val != sentValue) { // If value has changed from last transmission, send the updated value mys.send(msg.set(val==HIGH ? 1 : 0)); sentValue = val; } mys.sleep(BUTTON_PIN-2, CHANGE, 0); // Sleep until something happens with the sensor }
