Step 6Testing and Troubleshooting
Take your 9V battery and connect it to the 9V battery clip of your Metronome.
You should get regular beats from the speaker.
When you hear the first beat 1 LED should light up while the other is off. When you hear the second beat the LED that was on should go off and the other that was off should light up.
By turning the potentiometer the BPS ( Beats per Second) should increase or decrease, depending on witch way you turn the knob of the potentiometer.
Troubleshooting:
- Make sure that you put in the chip the right way.
- See if the speaker is wired correctly.
- The capacitor may be connected in reverse. It is important for the positive, longer or negative, shorter pin of the capacitor to be connected where it should be.
- Make sure that you connected the potentiometer like it should be. Once I soldered the potentiometer wrong and the circuit did not work. By quick reconnecting I got the circuit working.
- See if the battery clip is connected like it should be. Red wire to pin 8 and Black wire to pin 1, not the other way around.
- If just one LED is not working, its polarity is reversed so you need to unsolder it and reverse the pin configuration.
If you have a problem and you checked all these above, fell free to send a PM or leave a comment below regarding your problem!
