How HC-SR04 Ultrasonic Sensor Works Interface It With
Connection from Arduino Uno to Microsoft SQL Server Database. What Arduino does is getting fingerprint through sensor, then I would like to store the attendance records of a student into database. So the attendance records can be retrieved from database to the web application and display to teachers.

Connecting a 1602A LCD display and a light sensor to Arduino UNO 21 October 2012 This tutorial shows how to connect the 1602A LCD display and a light sensor to your Arduino (UNO) and display the light intensity on the screen.
Using a Temp Sensor - TMP36 Temperature Sensor - Adafruit
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to
Using a PIR w/Arduino - PIR Motion Sensor - Adafruit
A PIR sensor can be connected to a relay (perhaps with a transistor buffer) without a micro! TESTING A PIR CIRCUITPYTHON CODE This guide was first published on Jan 28, 2014.
Interfacing Pressure Sensor BMP180 with Arduino Uno
Using A Flow Sensor With Arduino. Share With: facebook twitter google. In this tutorial we will be hooking up a Flow Sensor to an Arduino Uno to measure liquid flow. This type of flow sensor is designed to measure the volume of liquid traveling past a given point, a great way to keep tabs on how much water your drip irrigation system is using
