In my desire to tinker with the SD card, I come up with a plan to create a mini karaoke player using Arduino microcontroller, Keypad and LCD shield as keypad and display, and SD card as data source of sound and lyrics files. Two weeks ago, I am able to play wav files from SD […]
Few days ago, I am thinking if I could create a mini karaoke using an Arduino Uno, LCD for the lyrics display, SD card for the sound files and the lyrics, and some switches for the playback functions. I tried to search through google and youtube for some resources but even the basic functionality of […]
After successfully accessing the SD Card with Arduino Uno the crude way (by soldering directly to SD card pins), I thought of making an mp3 player :). As a caveat, this design is not recommended for a daily mp3 player but it does play and I am happy with it. BILL OF MATERIALS So let’s […]
I wonder if I can interface SD card to a microcontroller without using any adapter or shield. After a quick search of SD card pinout in google, I found out that SPI is use in order to communicate with SD card. To minimize my effort, I then search for some reference and below are my […]
Today we are going to tinker something easy and simple but interesting. We will be exploring something musical by taking advantage of microcontrollers capability to produce voltage signals. Our goal is to produce a melody using and Arduino Uno and a speaker. The theory behind this is by generating a square wave signal and controlling […]
