LDR sensor
LDR Sensor Today, I made a circuit using an LDR(Light Detecting Resistor) sensor. An LDR sensor works on the amount of light present. To make this circuit, we need the following things: LDR sensor Breadboard LED Buzzer Jumper wires 9V battery To make the circuit, follow the following steps: Step 1: Connect the positive and negative terminals on the breadboard to make them common. Step 2: Connect the VCC of the sensor to the common positive on the breadboard. Step 3: Connect the GND of the sensor to the common negative on the breadboard. Step 4: Connect the negative of the LED and the Buzzer to a vertically connected line. Step 5: Connect the positive of the LED and the Buzzer to the common positive line. Step 6: Connect the DO(Data output)of the sensor to the line where the negative of the LED and the Buzzer are on th...
