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 6: Using a Photoresistor
Components needed PhotoresistorLEDResistorsJumper cablesArduino Uno boardBreadboardA USB CableA computer with the Arduino IDE installed Completed Circuit The circuit above shows the use of a photoresistor. As we learned in the previous blog, the resistance changes in potentiometer by turning the knob. Similarly the resistance in of the photoresistor changes based on light. More the light, … Continue reading Tutorial 6: Using a Photoresistor
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
