The infinity bug is connected across the phone-line of a distant phone in parallel mode. It uses surface-mount resistors, capacitors, transistors and diodes. It gets operating current from the phone line (leech device), no external power supply is required.
The project allows you to analyze characteristics of unknown/junk battery especially the capacity and variation of the voltage on discharge. It is controlled with a PC via a serial port. No external power supply is required because it is powered by RS-232C signals. It uses ATmega48 as main controller for dummy load and constant [...]
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 [...]
ArduinoDashboard is an application for viewing analog and digital pin sensor values from an arduino in real time. It will show the analog value of pins A0-A6 as well as the digital pins of 1-13.
