Touch Controlled Musical Bell. The details about the IC can be found ic um66 http: The time base for beat and tone generator is an inbuilt oscillator. Supply input pin 2 of the UM66 is given to the regulator output. Assemble the circuit on a good quality common board.
Sign up or log in Sign up using Google. Melody generator will reset when the power is turned on and then the melody begins from the jc note. Tone generator produces certain frequency. In this zener diode voltage regulator is used. Save my name, email, and ic um66 in this browser for the next time I comment. ic um66
You can not reprogramme it. New Organic Transistor by Im66 Probe: Sign up using Email and Password. Ic um66 mentioned in the features, the BT66T comes in five different part numbers.
integrated circuit – Replace UM 66 IC – Electrical Engineering Stack Exchange
Melody begins ic um66 the first note if power is reseted. It can also be easily interfaced with a normal Piezo electric speaker even buzzer or to a ic um66 ohm speaker through a NPN transistor as shown below. This will maintain output voltage nearer to 3. Thus an NPN transistor is used for amplification.
