SKIN TEMPERATURE MEASUREMENT

Abstract: This report represents the design and implementation of a skin temperature measurement system. The system aims to measure the skin temperature from a sensor and send it to the PC using a USB cable to display on screen. The data needs to be updated every second. The PIC18F4550 microcontroller has been used in this project to obtain data from the sensor and send it to the PC using USB 2.0 that has b ...

72 CHANNELS SERIAL TO PARALLEL DRIVER BOARD USING 74HC595 & ULN2803

72 channels Serial (SPI) to parallel driver board has been designed for various applications. This project can be used as multi Solenoid driver, large size 7 segment display driver, bar graph driver, and LED driver. The project works with 5V logic levels. Output load supply 12V-48V DC and each output can drive 500mA load. I have used 3 digits 2.3Inch 7 segment displays as an example, this board can handle u ...

UP/DOWN counter with memory

This is a simple digital counter with a serial rs-232 and a 7 segment display, i started this project to count items on some shelfs, but it can be used for anything, it is also, for the exception of the connectors, completely on SMD components. The circuit is made around a PIC16F88, and takes use of its internall EEPROM to store the number. Im using PORTA to connect directly to the segment display thru a 10 ...

How to Implement Embedded Ethernet

Usually We need embedded systems inside devices, particularly the so-called intelligent devices, to communicate with a command/control/administrative center. Typical such situations could be a remote security camera that can send you video clips when queried, an embedded system that can send status when checked through a web browser or a vending machine that is capable of sending an email when service is re ...

xPico WiFi SMT doesn’t require connector neither antenna

Lantronix xPico WiFi module may be already familiar to you from our articles, for example: xPico WiFi is a dream come true for producers and customers where we also mention the HW compatibility with the xPico module ( wired, serial-to-Ethernet modul). New version - xPico WiFi SMT brings the same functionality as xPico WiFi and as the name saysm it´s intended for a direct soldering by an SMT (reflow) process ...
