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
