IO-Breadboard-Development-System

The PRO-I/O breadboard development system emulates various input and output devices typically used in today’s designs. It plugged into a breadboard along its top row of connectors and provided input stimulus and output display for the circuit under development. The project include switches, pushbuttons, a 2×16 character LCD display, LEDs and even a small [...]

Expandable Serial Port Multiplexer

Serial-Port-Multiplexer

The Expandable Serial Port Multiplexer project allows a single RS232 serial port to service multiple instruments requiring RS232 ports. Each port is configurable in terms of baud rate, parity, number of bits and number of stop. On the host side the serial streams could be multiplexed through the use of a Windows driver [...]

LPT stepper motor driver

This project enables you to drive two unipolar stepper motor or eight electric light bulb or DC motors. There are eight DC power switch you can open or close through PC parallel port. For safety reason, digital interface to PC uses optocouplers. You can connect up to six circuits to a single LPT, driving [...]

Spectrum Analyzer

This 2.4GHz Spectrum Analyzer project build based on Cypress CYWUSB6935 module. The project allows you to monitor the 2.4GHZ ISM band in your immediate vicinity. You can monitor what’s going on and figure out what channel to change your Wi-Fi network to in order for it to keep working when your neighbor rudely sets up [...]

Arduino Controlling Images on 4D OLEDS

interfacing arduino - OLED

This tutorial inspired by serial OLEDS from 4D Systems. Jenny has pulls it together to make you easy learning how to Controlling Images on 4D OLEDS using Arduino. This project uses µOLED-128-GMD. Before you do any coding you can test run to see if the images are on the card properly by loading images on [...]

RS232 to Infrared Converter Project

August 10, 2009 By: admin Category: Digital, Interfacing, PIC, Wireless No Comments →

rs232 converter to Infrared

This is a Serial interface to IR converter project using PIC microcontroller. The project use Infra-Red to receive and transmit the data from serial interface. RS232 waveforms in this project operating at 5V TTL levels not +/-12V levels. It’s good to transmit your sequence of bits modulated as a series wirelessly.
