If you are using the 1088AS display, follow this wiring diagram to connect it to the MAX7219 and the Arduino: The resistor in the diagram above is the RSET resistor. It connects the ISET pin to Vcc to set the amount of current supplied to the LEDs. The exact value of RSET depends on...
The Max7219 works on in synchrony with the microcontroller it is connected to on a clock signal. On the rising edge of the clock signal are commands and instructions executed. So the clock pin of the Max7219, pin 13, connects to digital pin 13 of the arduino. This way, the microc...
}Code language:Arduino(arduino) This custom function will print a message that the alarm is activated and that we need to enter a password in order to stop the alarm. So using the next while loop we are constantly checking whether we have pressed a button on the keypad, and each button ...

. PWM can be time-based or frequency based. Time-based Modulation is mostly used for Boost Converter because it is simple to construct and use. The frequency remains constant in this type of PWM modulation. Whereas Frequency-based modulation has a wide range of frequencies to achieve the ...
