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 […]
This project is an 8-Degrees-Of-Freedom Robot. It is called 8-DOF-Robot because it has 8 servo motors. It has 2 servos for the left and right ankle, 2 servos for the left and right knee, 2 servos for the left and right hips, and 2 servos for the left and right shoulder. No movement for the […]
Have you ever think of what else could you do with your old PS2 Game Controller? What if you can use it to control something other than your PS2? Yes, it is possible with the help of microcontroller. In this blog post, I will walk you through on how to interface the PS2 game controller […]
To explore more with the functionalities of DF Player Mini, an LCD display is good added feature for this project. To save pin connection, we will use an I2C LCD. Since this is Part 3 of the series in tinkering with DF Player Mini, you may visit: Part 1: DF Player Mini – a mini […]
