Depending on the country, as many as 25 to 35% of motor vehicle accidents happen because of drunk driving every year. When drivers consume alcohol, they not only put themselves at risk but others on the road. Fortunately, such accidents are preventable with a combination of education, personal responsibility, and community efforts. There are also…
How to play MP3 files on Arduino using the DFPlayer Mini or the MP3-TF-16P
Including an audio option with an electronic or Internet-of-Things (IoT) project is often an ideal addition. However, microcontrollers cannot process MP3 files, which is the most common audio file format. Fortunately, there is a solution. It is possible to play MP3 audio files on Arduino using dedicated MP3 decoders like the DFPlayer Mini or MP3-TF-16P.…
How to design a weighing scale using Arduino
Weighing scales are frequently used to measure the weight of goods, such as bulk items and raw materials. We sometimes use them at grocery stores to weigh produce or at home to measure our weight. Building a weighing scale is no simple task. It involves a combination of load cells, amplifier circuits, and microcontrollers or…
How to build a paint application using Arduino
In this project, we’ll build a paint application on Arduino UNO/Arduino Mega that runs on a 3.5-inch TFT touchscreen display based on the ILI9486 driver. The ILI9486 touchscreen has a display resolution of 320×480 pixels. Using a stylus, you can draw, paint, and write on it (even in your own handwriting ). Required components Arduino…
