I want to add a notification LED to my digital multimeter which i need to glow with the multimeter`s inbuilt speaker (piezo/buzzer/beeper) while in Continuity testing mode.
MM Model : DT830D
If i have no other option except to replace the speaker with the LED then also please guide.
If i have to add any additional circuit to my MM then also please guide.
To make it simple i was thinkng to built something that will be connected in parallel or series with the MM`s speaker.
or is this possible to built a circuit that will only glow the led when the MM beeps.
Thanks in advance.
