LCFesR meter is a precise, wide range meter that can measure inductivity (L), capacity (C), frequency (F) and equivalent series resistance of a capacitor in-circuit (ESR) based on AVR ATMega88PA-PU microcontroller. It can be easily built with homemade one or double-faced PCB and available electronic components.
dr. Le Hung, project designer, explained that measurement of ESR [...]

The application presented here is software driven device that allows the user to test the servo motors used in remote control operated models such as cars, boats, planes and so on. The tester is developed based on M16C/28 microcontroller.
There are many opportunities when one may need to test a servo. Either the servo has been [...]

With RS232 quickly being replaced by USB, the nightmare of incorrectly wired appliances and forgotten baud rates will be a thing of the past. Unfortunately RS232 will still be with us for a long time to come and as it becomes used less frequently the exact parity and baud rates for devices can easily be [...]

AVR Code Debugger is useful tool to help you debug code without require resource in the MCU you are debugging. It only use 1 I/O pin, and is connected to a serial port from the host PC. Using a VT100 terminal to capture the output from the Debug tool, all of the debug information can [...]
