Atmel AVR Controlled Digital Capacitance Meter

The integration method was used to build this capacitance meter where it measures the time it takes a capacitor to charge to calculate the capacitance.

pH Meter Using Arduino Board

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass.

50MHz Frequency Counter

The project is a low cost frequency counter that utilizes widely available elements where the frequencies can be measured by the meter with 1Hz resolution when measuring up to 100kHz.

SRF04 Sonic Module for Distance Measurement

The project is a combination of an ATmega128 microcontroller and two SFR04 sonic modules with a controller unit MAM128 to produce a distance measuring device.

Digital Display with Clock and Temperature

The project illustrates a digital clock and temperature display which makes use of alternating display between time and temperature.

Accelerometer Logger Using SD Card

The project utilizes a SD card to save the forces measured on a roller coaster by this accelerometer logger unit.
