The tutorial is well planned and executed. I really liked the RGB LED and Sound show given at the end. I will try it and tell how it works. Till then you can read the rest of the article here. Working with Atmel AVR Microcontroller Basic Pulse Width Modulation (PWM) Peripheral The article also explain […]

ADC (Analog to digital converter) is a commonly used peripheral. We use it everyday to interface with several analog sensors. Many times a nice visualization of ADC data is required during learning about new sensors. For example you just bought a analog sound sensor, and try to do some fast experiments that how it performs.

An interesting project that can be done using Microcontroller is a LED message scroll er. It teaches you a quite lot of things. So I decided to make one. I made the hardware design modular and cascadeble That means the whole display is made up of several 15×7 modules. Each module has everything to drive

This ATmega168-based project monitors household power usage and logs it to an SD card. Signals from voltage and current detectors amplified LMC6484AIN quad op-amp and then AVR microcontroller computes the power consumption using the formula P=VxI. The voltage and current are each sampled at 9615 Hz so the integration should be fairly accurate even for
