Breadboard Diagram

Make the connections as shown in the figure above. Piezo: J15 and J20 (breadboard) LED: Anode and Cathode to g20 and g19 respectively on the Breadboard. Resistor: f19 and d19 on the breadboard. Jumper wire (red): connecting the PIN3 (of Arduino) and f20 (of breadboard) Jumper wire (black): connecting the GND (of breadboard) and -ve (of breadboard) Jumper wire (black): connecting f15 (of breadboard) and -ve (of breadboard) Jumper wire (black): connecting b19 (of breadboard) and -ve (of breadboard)
