A SIMPLE USB DATA LOGGING DEVICE

AVR Stick is a necessary information logging gadget that instantiates itself as a Concealed console and reports the voltages, alongside a period stamp from two pins on an ATtiny85. The device utilizes open source firmware accessible from Target Improvement called V-USB to execute the USB 1.1 standard. The code that runs the application depended on the Simple Lumberjack case application from Target improvement. 
The default firmware runs mostly enough connect it to a USB port on your PC, after the PC perceives the gadget as a console it will consequently begin reporting the voltages. To get a progression of estimations, open up content or spreadsheet manager and attachment the AVR stick in. The AVR Stick will naturally begin inputting the voltage qualities to whatever system is dynamic on the PC. The ADC is arranged to utilize a 2.56V reference voltage, so don’t take a stab at measuring anything higher than that without changing the code!
