A SIMPLE MANUAL CURVE TRACER using microcontroller

AVR ATmega Projects, Metering - Instrument Projects / Ibrar Ayyub

Measure current vs voltage or voltage vs current over limited range with good accuracy. This was built on a phenolic board which was mounted on a plastic box. The box serves two purposes: It holds the circuit off the workbench, and it makes a nice, stable mount for the potentiometer. Find updates at www.projects.cappels.org I

A Pretty Good LC Meter Based on the AVR using ATTINY2313 Microcontroller

A Pretty Good LC Meter Based on the AVR using ATTINY2313 Microcontroller

AVR ATmega Projects, Metering - Instrument Projects / Ibrar Ayyub

Calculates and displays L and C from oscillation frequency using reference components. No relays, no range switching, a minimum of controls. And it is pretty accurate too! Note: After reading this article, check out the improved, modified An Even Better LC Meter… The 2 line x 16 character LCD shows the calculated inductance and the

89Sxx Development Board using microcontroller

AVR ATmega Projects, Development Board - Kits Projects / Ibrar Ayyub

Introduction of 89Sxx There are some 89Sxx development board, here is another one. I have designed this single side development board to be used as a tool for learning MCS-51 Microcontrollers, and for easy microcontroller project development. The 89Sxx development board features : 89Sxx 40-DIL based design, 89S51/52/53 In System Programming (ISP) through the 6-pin header

Led Animation Circuit with PC Connectivity using AT90S2313 microcontroller

AVR ATmega Projects / Ibrar Ayyub

Animator is a device, rather 5 × 16 matrix LED , which are used to display simple animation. Initially, the device serves to something completely different and it was controlled directly from the parallel port for the program is written in Pascal. The idea has proved to be a bit pointless because the program does not provide an even
