Teach or learn about digital frequency counters with this simple low cost meter electronic kit from MadLab. A really useful tool for
the budding electronics engineer - a digital frequency counter meter. This kit comes with a pre-programmed PIC microcontroller. No programming is required.
Frequency Counter Meter Kit
A very useful tool for the electronics tech or engineer, this digital frequency counter meter from MadLab provides a lot of
bang for the buck. Based on the PIC 16C54 microcontroller, this frequency counter has an excellent price to performance ratio.
Frequency counter are often used 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.
