The buzzer is a very simple component. It has two legs. One for ground and one … Continue reading Tutorial 7: Using a Piezo (Buzzer)
Tutorial 5: Programming the Potentiometer with the RGB
Components needed Arduino Uno BoardBreadboardPotentiometerResistorsJumper CablesAn RGB LEDUSB CableA computer with the Arduino IDE installed Completed Circuit The image above shows the completed circuit showing the potentiometer controlling the color of the RGB LED. Changing the resistance, by turning the knob of the potentiometer, changes the color of the RGB LED. The Program int wiperPin … Continue reading Tutorial 5: Programming the Potentiometer with the RGB
Tutorial 4: Using a Potentiometer
Components needed PotentiometerLEDResistorJumper cablesArduino Uno BoardBreadboardUSB cableComputer with Arduino IDE installed Completed Circuit Potentiometer is a variable resistor. It has three legs (pins). Left most pin is for the power, right most pin is for the ground and middle pin is connected to sliding contact, called wiper, which produces variable amount of resistance as we … Continue reading Tutorial 4: Using a Potentiometer
