Test - Measurement Projects
PIC16F688 Digital Voltmeter
Introduction This project describes how to make a digital voltmeter using a PIC microcontroller.
Digital Room Thermometer
Introduction Room temperature plays a vital role in determining human thermal comfort.
PIC16F84A Gas Detector using GH-312 sensor
Introduction This is a gas detecting circuit capable of sensing many different types of gases.
DDS Function Generator
A new implementation of the AVR DDS signal generator v2.0 found at: http://www.scienceprog.com/avr-dds-signal-generator-v20 Introduction This is a new implementation of the AVR DDS signal generator v2.0, already published in scienceprog.com.
Single Chip Temperature Data Logger
Introduction A data logger is a device that records measurements over time.
Ultra High Sensitive Probe
Description This circuit is so sensitive it will detect “mains hum.” Simply move it across any wall and it will detect where the mains cable is located.
Voltmeter + Ammeter LCD panel
Introduction This multimeter was designed to measure output voltage and current in a PSU, where the current sense shunt resistor is connected in series with load at the negative voltage rail.
Simple Crystal Tester
Description Transistor Q1, a 2N3563, and its associated components form an oscillator circuit that will oscillate if, and only if, a good crystal is connected to the test clips.
Transistor tester
Description This is basically a high gain amplifier with feedback that causes the LED to flash at a rate determined by the 10u and 330k resistor.
Logic Probe Plus
This project is based on a probe logic states, capable of measuring levels from TTL (5v) to state levels of PLC’s (24v).
Logic Probe
Description This circuit is a Logic Probe.
