This high-quality, brand-new doorbell kit features a push-button switch that activates a unique 'ding dong' sound when pressed. Here's how it works: when the switch is closed, a capacitor charges, triggering a timer that produces two distinct frequencies, creating the 'ding dong' sound. The kit includes an 8 Ohm 0.25W horn, NE555 chip, various resistors, capacitors, and diodes, all packed in a beige, 28mm x 25mm PCB, weighing 15g. It operates within a 4.0-7.0V range.
- New and High-Quality: Ensures top-notch performance
- Switch Operation: Push button switch on the door triggers capacitor charging and initiates timer for 'ding' sound
- Capacitor Discharge: Switch release triggers discharge and timer for 'dong' sound
- Timer Functionality: Stops working once capacitor discharge ends and reset occurs
