Embedded Projects

This article provides detailed information on sampling audio signals and transferring the data to a PC for analysis.

In this article we’ll discuss the design for a custom microcontroller programming/debug/extension PCB and we’ll look at an example project....

In this how-to article, we explore the use of I2C EERAM to save critical program variables when power fails and restore them when power returns to easily preserve program continuity....

In this project, we will demonstrate the simplicity of RIOT by creating a data logger that will plot levels of light onto a graph on a PC server application....

In this article, I'll show you how I used one of my SIM900A GSM modules to send temperature and relative humidity to my personal website....

Remote controls for electronics often use IR (infrared) radiation in a very precisely coded sequence for channel surfing, volume adjustments, and more. One of the most popular codes is the SIRC...

Using a custom framework (RIOT) to control an LED with a networked computer.

The Beaglebone Treat-Feeder is the prototype for a great pet-feeding device! Keep track of your pet's diet while you stuff your face!

Use I2C on the Quark D2000 development board to interface a color sensor and get acquainted with using asynchronous mode.

Get acquainted with using I2C with the Quark D2000 development board by interfacing an ambient light sensor and an LCD.

Need to ventilate a room? This article will show you how I made a relay-operated, GPS-timed fan to vent out the moist air in my boat's cabin. It is controlled with a PIC16F628A and has an LCD....

This project gives you an example of how a basic user interface can be implemented using only one circular capacitive touch sensor.

In this project we will develop an algorithm for precisely locating a touch event that occurs somewhere on a circular capacitive sensor.
