the budding electronics engineer - a digital frequency counter / meter. This frequency counter kit comes with a pre-programmed PIC microcontroller. No programming is required.
Frequency Counter / Frequency Meter Kit
A very useful tool for the budding electronics engineer, this digital frequency counter / frequency meter from MadLab will give you
the most bang for the buck. Based on the PIC 16C54 microcontroller, this frequency counter has an excellent price to performance ratio.
A good use of the frequency counter is to calibrate other equipment. For example a signal generator that doesn't have its own digital display.
The meter will show the exact frequency being produced by the signal generator.
Texas Instruments manufactures a series of light sensors (e.g. TSL220) which produce an output frequency dependent on light intensity. They are
very easy to use requiring just one external capacitor. A light meter combining one of these sensors with this frequency counter could accurately measure irradiance over a 3 decade range.
Attach a crystal microphone to the frequency counter and you have a guitar tuner. The frequency counter will display the exact frequency
being played on a musical instrument. You can easily tune the instrument with reference to a table of note frequencies.
This frequency counter kit comes with a pre-programmed PIC, but if you like to learn about PIC source code, read and enjoy the
free digital frequency counter / meter construction article and source code
provided by MadLab.
