Stepper Motor Tutorial In this tutorial we are going to drive a Single unipolar stepper motor using PIC18F4550 Microcontroller in various different stepping modes. The source code and Project files are free to download at the end of this page. Stepper motor due its excellent features is very famous in between hobbyist for various robotic […]

Using a single super-power LED – 1,400 lm, emitting at 200Mcd/m2 – Osram has produced a dip headlight beam in its labs. The distribution of light indicates that car lighting standards can be met – see candela plot. “This LED has a luminance three times that of existing versions. This means that a single LED […]

Anthony from Cumaná, Venezuela, made his own “Persistence of vision” (POV) display, similar to my Air Display but it can be mounted on any bicycle wheels and it displays fifteen messages in Spanish. Here is the PCB with each part of the project. It uses a 12F629, works with a voltage of 3Volts This is […]

This reference design is a power management of Xilinx ZedBoard using MMPF0100 Power Management Integrated Circuit (PMIC). A PMIC is an IC for managing power requirements of the host system and is commonly used in a system-on-chip (SoC) device. On the other hand, the Xilinx ZedBoard, a development board based on Zync-7000 AP SoC, provides […]

Hi welcome to my 4th chapter of PIC18F4550 programming. Here we are going to learn another methodology or technique for programming a pic18f microcontroller which would be helpful in future while dealing with complex coding. We are going to define our own header file. We are also going to see the Source Code and will […]

There is a varied and growing market for LEDs in wearable applications, ranging from head torches and miners’ helmet lamps, through backlighting for head-up and near-to-eye displays, indicators for sports and medical monitoring devices, to fashion accessories and clothing. While LEDs have already become a popular embellishment, like sequins or beads, in fashion garments, they […]

ARM has thrown a large rock into the free-RTOS pool. The processor firm’s plans to offer a free operating system as part of its mbed development platform could see it competing with one-time software partners. One observer has even likened it to Google’s move into open source operating systems with Android. The mbed OS is […]

There is a multitude of process parameters nowadays that need to be measured in the industrial environment (temperature, pressure, humidity, force etc.). Out of these, undoubtedly the most common one is temperature, as it influences most manufacturing parameters. It is no wonder then that many solutions have been developed over time to measure it. There […]

The reference voltage plays a very important role in any A/D conversion. It determines both the range and the resolution (Volt/Count) of the A/D conversion. Besides, the accuracy of the conversion also depends upon how stable the reference voltage is. Usually in PIC microcontrollers, the reference voltage for A/D conversion can be selected as the […]
