Audio I/O

Audio Input Output

Adding sound to an electronics project is an ideal way for it to interact with people. You can use simple beeps to provide feedback or spice things up with some music to give a robot some personality.

Speakers are used to generate simple sounds or music and microphones enable sound waves to be translated back into electronic signals.

30mm Speaker - 100 Ohm - 0.15W

Code: AUD-50006

This automotive-quality 0.15W speaker is a compact way to add sound to your project. The 100Ω impedance makes it easy to drive this straight from a microcontroller I/O pin.

9mm Electromagnetic Buzzer: 40Ω, 4-6V, Top Opening

Code: SKU-002627

This electromagnetic transducer is a compact way to add sound to your embedded project: just supply it with a PWM signal at 4 V to 6 V and it will produce sound at the frequency of the supplied signal from an opening on the top.
