PWM Signal Generator Electronics Kit

If you are in need of a PWM signal source for testing purposes then look no further as this kit will let you create your own PWM generator! PWM Signals are those that have variable duty cycles and are found in many thousands of circuits. Just a few examples of how PWM signals can be used include Digital-To-Analog conversion, high-efficiency power controllers, servo control, timing, and much more. This kit will allow you to build a simple PWM generator that runs on voltages between 5V-28V and has two potentiometers for adjusting both the frequency of the PWM wave and the duty cycle between 0% and 100%.
The kit is ideal for those teaching op-amps and the various circuit configurations they can be used. Furthermore, the kit also teaches about positive feedback and how to convert a triangular wave into a PWM signal. The small component count combined with the two large potentiometers makes an ideal product for a DIY function generator that is to be mounted inside an enclosure, and the construction time of less than an hour is also ideal for use in the classroom.
