I use another circuit different from the ones we have seen in the course to amplify the signals, but the basic principle is the same. I also put a passive speaker on the breadboard, so this installment has no need to rely on the external speaker. | I use another circuit different from the ones we have seen in the course to amplify the signals, but the basic principle is the same.
