Hi Im am working on a project that involves the use of an OLED display as well as 2, 32 ohm speaker drivers and I have a diagram of my wiring I would like to know if the hardware on this looks right or if i need to add anything,
-Thanks ![]()

Hi
Please explain your project in more detail. Where the audio input coming from? What is the purpose of the OLED?
What is the module between charge board and Arduino? Is it a power buster? What it's output voltage?
In schematic - why did you draw a separate (pink ??) GND line for OLED and audio board? Why don't use a common GND with a power supply?
Do not power the amplifier from the Nano, you may damage the Nano. Power the amplifier from another supply.
Hello Sorry for not providing enough detail the module between the charge board and the arduino is a bluetooth audio receiver similar to this Link
The purpose of the OLED display is to project an animation onto the screen and then have 2 headphone drivers play audio from the bluetooth module. the audio input is coming from the bluetooth audio receiver module which connects to my phone and plays music. I essentially want the oled screen because i think it would look cool if the headphones projected some kind of animation and I also do not understand what you mean by a separate ground from the oled i have 2 grounds one for providing 5v power from boost converter to the arduino nano and another for providing power to the bluetooth audio receiver module and the oled screen
Hi, sorry for not clarifying this is not a amplifier it is an bluetooth audio receiver module will i still be able to power the amplifier from the arduino nano?
Is this some fixed animation or something randomly driven from the audio source? I ask because at the moment there is nothing going from the audio source to, say, an analog pin.
The board at the top, between the charger board and Nano does not look like a Bluetooth board nor is it connected to any data IO. Has it been omitted? The graphic and connection make it look more like a power switch?
I would like it to be driven from the audio source if possible i would like it to produce an audio visualization of the music playing if that is possible from the bluetooth module
also on the website i used for making the schematic, the board that you say looks like a power switch is called the Bluetooth 5.0 Audio Receiver Board-Controllable Volume
here is the closeup of the circut it has 5 connections +, -, Left, Right, And GND(Left and right are for headphone drivers)
No.
You will burn out the Nano
Is your battery really 150mAh? You're going to be very disappointed by how long it lasts in this circuit!
Do you really mean "project"? If you place a large lens in front of the OLED display, you may be able to focus an image onto a small screen or wall in a completely dark room.
Would the animation be synchronised to the audio in some way? If so, how could that be? There is no data/signal connection between the Bluetooth module and the Nano for synchronisation.
i don't mean project i meant display, I also realized that it would be almost impossible to do that so i think im just gonna have a normal animation on the oled screen second of all my battery is going to be 1250mah instead. Third of all I too am quite worried about the battery life for the circuit is there any way i can have a decently long battery life as well as have a simple oled animation that is being displayed on the screen and and audio output from the headphones?
2 hours? 2 months?
Either way, the answer is yes. You need to calculate how large a battery will be needed.
Your 1250mAh battery will provide approximately 1250mA for 1 hour, or 125mA for 10 hours or 12.5mA for 100 hours.
You need to know how many mA the circuit will consume and use that to calculate how long your 1250mAh battery will last, or what capacity battery you will need to last 8 hours.
The Nano will probably consume approximately 20~30mA. The OLED approximately the same. As for your Bluetooth audio module and headphones, I don't know, but I guess will will consume more current than the other components.
