The project aims to show how waveforms and signals can be displayed on a VGA monitor using a few resistors, capacitors, and an ATtiny84 microcontroller that runs at 20MHz.
The project aims to build a digital sensor thermometer based on TMP275which is 0.5°C accurate and uses 2-wire interface to connect to a microcontroller.
This electronic meter was created in order to measure distance covered by a bicycle using magnet and magnet sensor contact for proximity effect to sense the turning of the wheel.
An AVR ATmega8 microcontroller and an operational amplifier is used to build this spectrum analyzer which can improve the audio quality of an equipment.
This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor.
