Tempo tap circuit using IC-CD4011

This Tempo tap circuit will have an effect than Tap the rhythm circuit other because the whistle is giddy, which vividly than usual knock. You can also adjust the speed with 10-40 strokes per minute.

Operation of the circuit

Tempo tap circuit using IC-CD4011

We will divide this circuit into three main parts of the schedule, the frequency generator, the control and amplify signals. The timing is IC1a, IC1b is a device to build up the frequency.

This frequency is determined by R1, R2, C1, C2 and VR1. VR1 will be controlled by frequency And the frequency will be set of Q1, which works to affect Q3 Q1 Q3 to work intermittently The frequency generator is IC1c, IC1d frequency generator to drive out to the speakers.

The frequency determined by the C3, C4, R5 and R6 signal will be expanded to drive the Q2 and Q4. But Q4 will not allow signals to pass the time. Q3 to control because it will work again in Q4. And Q5 connected with acts amplifiers to speaker, with a VR2 adjust the volume.
