Description The simple 8 channel LED chaser has been a very popular project on Picprojects since it was first published a couple of years ago.  During that time there has been a demand for a board that could drive more LEDs so I started designing a new version of the LED Chaser using MOSFETs.  What […]

The CircuitMaker PCB design tool could be thought of as the electronics enthusiast’s equivalent of Picassa, the free alternative to Photoshop – except that it’s a got a much more refined interface which makes it easy use. The program’s 3D modeling capabilities (more about that later) and other advanced features will help designers deal better […]

Satellite Subsystems Irrespective of the intended application, is it a communications satellite or a weather satellite or even an Earth observation satellite, different subsystems comprising a typical satellite include the following: Mechanical structure Propulsion Thermal control Power supply Tracking, telemetry and command Attitude and orbit control Payload Antennas The structural subsystem provides the framework for […]

Our first chipKIT tutorial is about reading and writing digital data (0 or 1) from and to an I/O pin of the chipKIT board. Digital inputs are useful to determine whether an incoming digital signal is logic HIGH or logic LOW. A simple application of digital input is reading the state of a push-button switch […]

The PIC32 processor on the chipKIT Uno32 board provides two hardware serial ports. One of these is used by the on-board FTDI chip to create an USB-UART interface that allows the MPIDE tool running on the PC to communicate with the Uno32 board through an USB port. In this tutorial, we will use the same […]

If you dig around in your camera’s settings long enough, you’re almost assured to find that it has a mode to create time-lapse videos — those magical, time compressing movies that can turn any hillside or street corner into a lightning-paced dreamscape. Time-lapse videos by themselves are easy enough to make, but if you do […]

In order to understand the chipKIT platform, it is important to talk about Arduino first. Arduino is an easy-to-use and powerful open source environment for developing microcontroller based applications.Chipkit Development Board It has gained huge amount of popularity in past few years, specially among hobbyists. Arduino has been a wonderful tool, introducing many people to […]

This is a third project in our chipKIT tutorial series and today we are going to construct a simple pulse rate meter using our Easy Pulse sensor with Digilent’s chipKIT Uno32 board. Digilent’s chipKIT Basic I/O shield is also used in this project for displaying the pulse waveform and the pulse rate. What do we need? In order […]

I2C or IIC (Inter-Integrated Circuit) is a simple bidirectional serial interface, which requires only 2 signal lines for data transfer. It was originally developed by Philips in 1980′s to provide easy on-board communications between a CPU and various peripheral chips in a TV set. Today, it is widely used in varieties of embedded systems to […]
