This DIY Doorbell Kit, powered by a NE555 chip, comes with components like 100UF and 10UF capacitors, and other essential parts. It operates within a 4.0-7.0V range and features a compact PCB size of 28mm x 25mm. The kit's horn is an 8 Ohm 0.25W speaker. It includes a horn, red and black lines, the NE555 chip, an 8P IC block, and various capacitors and resistors. The circuit produces two distinct frequencies for the speaker, creating 'ding' and 'dong' sounds.
- New and High-Quality: Enjoy a fresh, top-tier product
- Doorbell Switch Operation: Press the door's push button switch (s1) to charge the capacitor, initiating a timer that produces sound frequency f1. Release the switch to discharge the capacitor, generating a different frequency (2f). The timer resets once the capacitor is fully discharged
