Do you want to make a MP3 player, a drum machine, or a talking weather station on Arduino? Troyka can help you with this. Add it to your project, connect the speakers or headphones and your device will sound great.
Some microcontrollers can play sound via the built-in digital-to-analog converter. However, speakers cannot be connected directly to the contacts of the microcontroller. The contacts on the microcontroller produce too little current, and the signal from them contains a constant noise component.
This Troyka audio output amplifies the signal and removes the DC noise.
The module is connected to the four pins of the controller:
The input signal can be recorded in stereo mode or, by unifying the channel by jumping the contacts, you can transmit the signal to two pins.
Audio sources are connected to the module via a 3.5 mm TRS connector (mini-jack).
Connect the module via 3-pin jumper cable. The 3-pin jumper cables needed for the connection are included in the kit.
There are several different ways to wire this module:
Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.
Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.
Breadboard. For advanced use. Troyka pin headers have 0.1” spacing which is compatible with any breadboard. Simply wire the module like you would do with any IC.
