Telephone Ring Bell Circuit works on 4.5V to 12V power and generates home telephone ring bell sound. It can be used with homemade intercom. CD4060 generates three different frequencies pulses. That generate the telephone ring from piezo buzzer. You can adjust the sound with pot on pin10. Circuit generates louder sounds while being operated on 12V so there is a volume control in series of the buzzer. ---------------------------------------------------------------------------------- Like👍 ll comments📝 II Share📢 ➡️Keep Supporting🙏 ---------------------------------------------------------------------------------- . . ---------------------------------------------------------------------------------- Follow (@nationin) for more stuff. ---------------------------------------------------------------------------------- . . _____________________________________________________ #telepjone #ring bell #circuit #signal #frequency #modulation #communication #basics #learn #digital #analog #technologynews #tech #technology #world #science #friction #insta #instagood #learners #techno #instadaily #instagood #electronics #electricals #electricalengineering #engineering https://www.instagram.com/p/B8OiHHLnRmU/?igshid=k56lz74hc4ox
