This project turns Arduino into basic web server which is hooked up to the LCD. You can enter text strings via web page and display them on LCD attached to Arduino. On the simple HTML web page, you will also see what text is currently displayed on the LCD. For further project, you can develop it to web remote control.The real challenge to this project was working within the limitations of the Arduino as a computing device. To build this project you need An Ethernet Shield for Arduino. Download source ...

The project shows you how to build ballistic chronograph based on PIC18F13K50 Microcontroller. The project only been tested with a paintball gun and it is relatively simple to make. It also can record the rate of fire at which a device is firing. The operation of this projectile velocity meter is rather simple, there are two IR transmitters and two IR Detectors, each transmitter/detector pair is placed exactly four inches apart.When an object breaks the first beam the microcontroller starts a timer (Timer1). This timer will keep running until the ...

This speed detector uses two photo resistors paired with laser as a form of trip wire. The Arduino Duemilanove with an ATMEga328 captures the tripping action and calculates the amount of time between when each sensor was tripped. By dividing the distance between two trip wires with difference time value, you will get the SPEED.Instead using LCD, the project uses flash program to display speed meter. Once the speed has been calculated, Arduino send the data to flash program using serial port and display the speed data.Speed Meter Project Firmware, Schematic ...

This little instrument, named as Pico C, can be used to measure capacitances down to fractions of a picofarad. It built based on ATtiny2313 microcontroller. It has range: <1 pF to 2000 pF (guaranteed); 2500 pF possible and resolution: 0.1 pF. To read the result, this low cost C meter comes with 2 lines LCD. The project is easy to calibrate with 1000pF 1% reference capacitor.This tiny capacitance meter is good tools for RF designers and radio amateurs. Since many built-in capacitance meter digital multimeters comes with lowest measuring range ...
