PinMode(ble_gnd,OUTPUT) // turn on bluetooth againīle. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Hello, ive found program written for arduino nano, but I have arduino mega, could anyone explain to which pin on arduino mega I should connect everything Program says: const uint8t MELBUSCLOCKBITINT 1 //interrupt numer (INT1) on DDR3. Each of the 50 digital pins on the Arduino Mega ADK can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions. I wonder if theres a complete list of all the interrupts (and vector names) somewhere that I can write down in my notes. I made a first sketch but the result on the serial monitor is incomprehensible. Hi, Im learning to use the Interrupts, but most info is about the UNO (ATmega328) and not the MEGA (ATmega2560) which Im using for my current project. I want to use this configuration to work with an interrupt (int.0 on pin 2) at 1hz. Serial.println("MOTION") // notify through serial port Arduino nano pinout vs arduino mega 2560. Hello all, I’m trying to control my Mega board 2560 with the SQW signal from an RTC DS1307 Shield. LowPower.powerDown(SLEEP_FOREVER, ADC_OFF, BOD_OFF) // sleep until interruptĭetachInterrupt(digitalPinToInterrupt(interrupt_pin)) //stop interrupt to allow program to run // All delays need to be multiplied by the ratio of crystal speed. Initiate (attach) interrupt, sleep, and wait for motion sensor to tripĪttachInterrupt(digitalPinToInterrupt(interrupt_pin),wake_routine,RISING) Serial.begin(9600) // uncomment if you want to read through serial portīle.begin( 38400) // for 4 MHz crystal use 38400 // for 16 MHz crystal use 9600 Specify the input pin that is used for external interrupt here. #include //low power library #include //serial communication for bluetooth #define interrupt_pin 2 // interrupt pin #define ble_vcc 8 //bluetooth + #define ble_gnd 7 //bluetooth - #define ble_TX 5 //bluetooth TX #define ble_RX 6 //bluetooth RX ISR has following syntax in Arduino: attachInterrupt(digitalPinToInterrupt(pin), ISR, mode) digitalPinToInterrupt (pin): In Arduino Uno, NANO the pins used for interrupt are 2,3 & in mega 2,3,18,19,20,21.
