Circuit Connection (Step-by-Step)
• ​Step 1: Connect the VCC of the rain sensor to the positive terminal of the 9V battery.
• ​Step 2: Connect the GND of the sensor to the negative terminal.
• ​Step 3: Take the Digital Output (DO) from the sensor board and connect it to the Base (middle pin) of the BC547 transistor.
• ​Step 4: Connect the Emitter (left pin) of the transistor to the negative terminal of the battery.
• ​Step 5: Connect the Negative terminal of the Buzzer/LED to the Collector (right pin) of the transistor.
​Step 6: Connect the Positive terminals
