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 internal A/D converter to sample and digitize the incoming signal, external  I2C 8-bit D/A PCF8591 […]

Written by Rui Santos – Get free updates of new posts here In this project you’re going to make two ESP8266 talk with each other. How it works? You’re going to set one ESP as an Access Point (Server) and another ESP as a Station (Client). Then they’ll establish a wireless communication and the Client sends a message […]

This project produces a number of effects on a set of three LEDs. You can also produce your own sequence and store it by using the 3 buttons. You can build the project on Matrix Board or buy a complete kit with pre-programmed chip. You can also program the chip yourself and use this project […]

Build a timer with Motorola Nitron MCU and using ICC08 to develop c program. Loader schematic also included. New s-record for 8-pin 68HC908QT2! My son got his fan in the bedroom. The fan has mechanical timer for 0-180mins. One day it broken. So I got the idea to use Nitron chip to replace the mechanical […]

When we are choosing PIC microcontrollers for projects on electronics or electrical, there are many options for us. Ranging from eight bit to Thirty two bits, diverse micro-controllers are accessible to go well with projects and products of different complications and cost restraints. But if we talk about student projects, it may be either major […]

GaN Systems (Ottawa, Canada) is to display its GS66540C 650V 100A high current GaN power transistors for the first time at the 17th Conference on Power Electronics and Applications, EPE’15 – ECCE Europe (CERN, Geneva, September 8th – 10th ) The GS66540C (the picture is of a prior, lower-current part) high current power devices will […]

Description   The LMX2581 is an ultra low noise wideband frequency synthesizer which integrates a delta-sigma fractional N PLL, a VCO with fully integrated tank circuit, and an optional frequency divider. The LMX2581 integrates several low-noise, high precision LDOs to provide superior supply noise immunity and more consistent performance. When combined with a high quality […]

The microcontrollers plays an essential role in the embedded industry  after the development of Intel 8051. The research in the field of embedded  industry gave high efficient, low power consumption microcontrollers. The Arm, AVR and PIC microcontrollers are the prime examples. These microcontrollers are getting smart with communication protocols such as I2C, USB, SPI,CAN and […]

This is a library for interfacing with the HID features of the MCP2221 USB to UART and I2C/SMBus serial converter from Microchip. The converter includes 4 GPIO pins, 3x 10-bit ADCs, 1x 5-bit DAC and more. Microchip does provide a library for interfacing with the chip, however it is supplied as proprietary DLLs. This project […]

Description Since I published the original RGB LED driver (photo right) I’ve had many enquiries from people asking how they could make the original board work with more LEDs.  I’d already made a couple of custom boards up for myself, so I finally decided it was time to put together one for the website. The […]
