![]() ![]() ![]() The repository contains instruction on how to install and use it. hmm, this is the second time his name has been mentioned. You can find the code for this project in my GitHub repository You will also need LittleFS uploader for Arduino, to get it, go to this repository by earlephihower. , also download ArduinoJSON by Benoit Blanchon ![]() To download the libraries, in your Arduino IDE, navigate to sketch>include library> manage library, then type in DF mini player and download the one by Makuna If you want to create a professional PCB rather than do it by hand like me, you can download the Gerber file from here.īefore you upload the codes you would need some libraries. NOTE: To power the whole circuit you only need to connect the micro USB port on the Vero board to 5v and that is all, but If you want to upload code while the node MCU is part of the circuit you will have to plug in both micro USB ports. If the so-called security feature confuses you, you don't have to understand it to build this project just ignore it. A workaround is to upload the code before adding the node MCU to the circuit or power both the mp3 and the node MCU like this With this feature□ no one can change or re-upload a new code to your node MCU unless they know if this feature□. ![]() The node MCU gets power via its VIN pin however, its micro USB port is not connected to the VIN pin, so if you power the board via its micro USB port when trying to upload code the mp3 board will not get power but they share a common ground and the TX pin of Serial1 of the node MCU is connected to the Mp3 module, so when you try to power the board via its micro USB port, the Mp3 module will try to pull power from the TX pin which will render the node MCU unable to enter download mode for code upload. There is a design flaw in this circuit that also serves as a security measure. The connections are simple and few, so this shouldn't give any difficulty soldering. ![]()
