In this article I’ll demonstrate a digital stopwatch design based on PIC16F876A micro controller.For related circuit based on Arduino click here. Similar project showing a Digital Timer design can be found here. Current circuit can be used to count in ...

In this post I'll show a simple running LED circuit. Currently only 2 patterns are available but additional effects can be easily added by slightly modifying the code. This design uses only 16 LED's however PIC16F877 has 5 I/O ports ...

Power Supply is probably the most common electronics project you can build.This is a basic design for digital power supply. It was built around 3 main components. Digital potentiometer – MCP4251-502E/P, Low  Dropout Voltage Regulator – MIC29152 and PIC16F877A.The idea ...

Light emitting diode (LED) Controller was built using PIC microcontroller and LM317 regulator. Comparing to traditional light sources led illumination should provide more efficient lighting also giving you a possibility to choose desired wavelength. 48 white diffused LEDs connected in parallel ...

This is a new revision of 10 bit Digital Voltmeter. For Arduino based voltmeter click here. Recently I’ve published a few voltmeter designs ranging from a simple LED display voltmeters with 8 bit of resolution to a more complex with 10bit ...

Recently I was asked to build an aquarium lighting controller prototype to provide variable brightness during its operation and ability to program  ON/OFF times. 25 blue and white diffused 10mm LED were used to illuminate the aquarium. The main requirement from ...

This is a modified version of basic wave generator design with AD9850 and Microchip PIC16F microcontroller. A relatively simple assembly code available for download at the bottom of the page. Instead of using a rotary encoder as many other similar available ...

In this article I’ll show you how you can use PIC microcontroller to record and store waveform patterns in its EEPROM memory and replay the sequence later. For this purpose we’ll need a signal/waveform generator to produce the signal, PIC ...

This very simple design shows how to make a blinking LED using PIC16F684 MCU. In my previous post I’ve used PIC16F877/86 however most of basic circuits do not require a lot of I/O pins and PIC16F684 small 14 pin package is more ...

This is an upgrade to recently published Simple Digital Voltmeter.Few improvements were done to hardware and software.DVM operating range  was slightly increased up to 24 V Max, however the most significant change is that the code now uses full 10 bit of ...
