What Is It? As the name suggests, in this project you will learn how to create a display for your bike that consists of both a speedometer and an odometer. Indicating real time speed and distance travelled. The total cost of this project comes to around 15 USD (not including the bike or the Arduino) yet the effort spent is worth […]

Almost all electronics have some sort of human interface, from blinking lights and beeping speakers to seven segment alphanumeric and Liquid Crystal Displays. This Instructable is about salvaging and testing Liquid Crystal Displays, and a couple tricks I know to make salvaging them more successful. I salvage; components can get expensive, LCDs can run $10.00

SUMMARY A device that can be used to control up to 4 different Hydroponic/Aeroponic Systems at once. The device will control the components of the system and will display notification to a LCD screen and allow the user to customize settings via Bluetooth. This system will be user friendly and optimized for fast growing so
Here we describe interfacing of three 16×2 LCDs with common data lines to an Arduino Uno board. Four data lines of all the three LCDs are connected to digital pins of the Arduino Uno board but data displayed on each LCD is different. Circuit and working The circuit diagram for interfacing of three LCDs with

In most electronic systems, it is necessary to provide information in the visual form for a convenient user interface. The most commonly used displays in electronic systems are LED, LCD and TFT. Amongst these, an LCD display is the most cost-effective solution as it can display alphanumeric characters along with special user-defined symbols. It also

The purpose of the Home Energy Monitor Final Project is to give people a better idea how much electrical power they consume in a residential system. The method used for this application will utilize a clip on noninvasive current sensor on each 120V line coming in to the residential breaker panel box. The power data
