This project is based on a probe logic states, capable of measuring levels from TTL (5v) to state levels of PLC’s (24v). For this we have employed the use of the PIC 12F683 microcontroller, which by its nature is capable of operating at low voltages, in this case 3vcc, besides having analog inputs and internal […]

The Inter-Integrated Circuit or I2C (read as I square C) bus has been introduced in 1980 by Philips, and has become a de-facto world standard for data exchange between Microcontroller and various devices such as temperature sensor, ADC (analog to digital converter), DAC (digital to analog converter), I/O expander, EEPROM, and many more. With more […]

If you are mainly involved in designing or repairing digital devices, a logic analyzer is more useful than an oscilloscope for tracing signal through circuits. However, does this mean you should rush out and buy a logic analyzer? The instruments from the leading manufacturers are too expensive for home use or startup businesses, and the […]

A Project entitled “PIC Microcontroller Unit” presented by Quezon City Polytechnic University (QCPU), Fourth year students of Bachelor of Science in Information Technology (BSIT), Major in Computer Technology. For the elecytive subject of “MIcroprocessor”. Submitted by Group number two(2) and to be submitted to Professor Ambito. For School Year 2012-2013, Second Semester. Group Members: Graellos […]

The project uses flashing LEDs to present shot message in the air by swinging a wand around above the head. A perfboard is used to construct the circuit that is powered by 2 coin cells type CR2016. The power fluctuations from excessive load on the coin cells can be prevented using the electrolytic capacitor. A […]

One of the advantages using the Microchip PIC microcontroller Pulse Width Modulation or PWM for short is; this PWM peripheral circuit is designed to control the DC motor using the full bridge mode PWM feature. The PWM peripheral works by supplying the correct signal to the H-Bridge DC motor circuit such as speed controlling and […]

Light propagating in a layer of scattering nanoparticles, shows the principles of diffusion – like tea particles in hot water. The deeper light is penetrating into the layer, the lower the energy density. Scientists of University of Twente’s Complex Photonics Group, however, manage to turn this falling diffusion curve into a rising one, by manipulating […]

Imagination Technologies wants to raise the profile of mobile graphic processor design in university teaching with a new course as part of its online Imagination University Programme. “An Introduction to Mobile Graphics” includes a rich set of teaching materials and practical exercises and will be based around Imagination’s own PowerVR graphics processors (GPUs). According to Imagination, […]

The LEDactus is my version of a dry climate niche dweller like a cactus. LEDactus is immobile and attempts to survive by creating a pleasant display. This is of course in the hopes that passersby will be so entranced that they will build the LEDactus’ progeny. Initial generations create a simple but pleasing display. Later […]

Learn how to combine a PICAXE, IR sensors, and a servo motor to create a device that responds to a moving stimulus. Spoilers: I hook it up to eyeballs that can follow a finger. Related Information Servo Motor Control with an Arduino Servo Control with Arduino Through MATLAB Servo Control via USB with the SAM4S […]
