The sound output from the ic can t however drive a speaker directly as this puts strain on the device. Also a 10 kω resistor and 50 kω pot between pin 7 and pin 6. Door bell circuit door bell circuit.
In 555 timer ic1 we have associated a 1 kω resistor between vcc and pin seventh of the 555 timer.
Here we have utilized two separate 555 timer clock ics to deliver the required ding dong sound frequency. The sound output from the ic can t however drive a speaker directly as this puts strain on the device. This simple and cost effective ding dong electronic doorbell circuit is based on ic 8021 2.
