This project Temperature Display using an LM 35 temperature sensor and no less than 70 LEDs driven by a pair of 74ls47′s. Watch out for the format of the drill file, the decimal place is not included and the right 3 digits of each coordinate are fractional. The PCB is single sided and uses SMT [...]

Project separated into two PCBs (PSU+PIC and UI board). The PIC microcontroller PIC12F675 does all the hard work, it emulates remote controller by sending some custom RC5 codes, measures ambient light level and decides whether it is day or night and receives trigger-signal from the IS471F sensor. On this PCB there is a power supply [...]

For a long time now I’ve been wanting to make my own microcontroller-based prototyping board. My original motivation was the unjustified high costs for even the simplest boards (a basic Arduino for $30 – why???) and the challenge of designing something that anyone can make at home within a few hours, with parts that can [...]

Mikroelektronika released a new BETA version of mikroC PRO for PIC compiler with a lot of useful upgrades. Compiler is now supporting more PIC microcontrollers: PIC12F617, PIC18F13K22, PIC18LF13K22, PIC18F14K22 and PIC18LF14K22. Make your comments alive with new feature called Active Comments. New and improved libraries and new set of example projects are available for users [...]

This dimmer it can’t be used for light dimming and it can control those power saving fluo-bulbs which have internal electronics/converters. The controlling element is solid state relay  (SSR) which consists of opto-triac MOC3043 (MOC3042) and a triac (ie.: BTA16, BTA08, …). This combination enables us to turn ON/OFF all kinds of appliances (motors, lights, [...]

This project is useful for repairing broken PC monitors. The monitor tester uses ATTiny2313 AVR MCU running at 20MHz speed. Power supply is made using one xx2950 device chosen because its low quiscent current, important factor for battery powered devices. You can use an 78L05 equivalent integrated circuit if you are not interested in consumption [...]

New tool from mikroElektronika called Package Manager. This tool will bring a new great flexibility in development and sharing of libraries, sources, definition files and examples. The Package Manager is a tool which enables users to integrate their own libraries in the mikroIDE. Besides installing new libraries into the mikroIDE environment, the Package Manager can [...]

A VU meter is often included in audio equipment to display a signal level in Volume Units; the device is sometimes also called volume indicator (VI). In this project we are building a basic and low cost LED VU Metre circuit . The extent (range) display is -18 dBu to +3 dBu, spread over eight [...]

This example will show you how to build a PIC based simple memorization game system. With only a PIC16F84A and a few cheap components, you will train your brain first to understand a few basics about PICs, second to play to a not that easy memory game ! Source: micro-examples

Today we have a new category “Projects” and a new electronic  project 12 Channel LED Chaser with PIC16F84A. This project is based on the popular PIC16f84A micro-controller.The heart of this project LED chaser is the PIC16F84A PIC microcontroller.A 4MHz crystal and capacitors C1 and C2 22pf is used for providing clock pulses to the micro-controller. [...]

For transfer of digital audio between devices is standardized S/PDIF interface (electrical) and TOSLINK (optical) for commercial use, or AES3 for professional use. S/PDIF decoder module is used for converting of this interface to I2S interface, which is usually used on audio DACs. For conversion we can use for example integrated circuit CS8416 or DIR9001. [...]
