GND (3): Short for ‘Ground’. There are several GND pins on the Arduino, any of which can be used to ground your circuit. 5V (4) & 3.3V (5): As you might guess, the 5V pin supplies 5 volts of power, and the 3.3V pin supplies 3.3 volts of power. Most of the simple compon...
Unfortunately, the LED may turn on when it is not supposed to due to a floating voltage on pin 11. To overcome this problem, you may need to connect a1 Megaohmresistor between pin 11 and GND. Serial Communication: A Way To See What Your Arduino Is Doing ...
Place the RGB LED on your breadboard with the longest pin as the second from the top. Check the datasheet for your specific LED to verify the pins, but they should be R, V+, G and B. The wire from 5V should therefore connect that second pin from top, as in the connection scheme ...

The ArduinoMega has four hardware serial ports that can communicate with up to four different serial devices. Only one of these has a USB adapter built in (you could wire a USB-TTL adapter to any of the other serial ports).Table 4-1shows the port names and pins used for all of the ...

The current implementation supports direct connection to IO pins of your Arduino or an indirect connection over I2C to a PCF8574 chip, where the display and keys/buzzer are connected. You need one chip for the display and one for the keys and buzzer. If you have the pins, use direct ...
Supplying more than the operating voltage of the Arduino on any pin is very dangerous. Some Arduinos that run at 3.3v have 5v tolerant pins, but that's about it. This also holds true for other devices, like sensors or wireless chips: always check the voltages: if you connect the output...
