GND is the ground pin of the Sound Sensor module and it should be connected to the ground pin of the Arduino. DOUT is the Digital output pin of the board, low output indicates that no sound is ...

Circuit & Working. Circuit shown below operates using a minimum of 5V DC power supply (Across Vcc & GND pin of Arduino UNO). The Arduino itself requires only 5V to operate but considering the fact ...

Utilize a power supply with a ground pin: Power supplies without a ground pin may result in incorrect grounding. To ensure appropriate grounding, utilise a power supply with a ground pin. Employ ...

There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra com… ...

Arduino Uno with LCD/Buttons shield on a breakout board. the area occupied by "ca1" shows each test combination that is tried and whether there was conductivity (1) or not (0). ca was the last attempt ...

The Arduino IDE is used to write the program that will interact with your Arduino and the devices connected to it. In the Arduino world, such a program is called a sketch, which has its origin in its ...

Arduino Uno is a robust choice for beginners and prototypes. It's based on the ATmega328P and offers a good balance of GPIO pins, is easy to program, and has extensive community support. Arduino Nano ...

Arduino is strictly bootloader, and a bootloader cannot change fuses. “How do I reconfigure the IDE so that I can use these additional two pins.” The same way you SHOULD use the other pins.
