Overview
Product Description
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%.

Applications
- The PWM Generator is an ideal kit 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.
- Education and training – Useful for teaching pulse-width modulation, duty cycle and oscillators, while providing practical experience with through-hole soldering, component identification and PCB assembly.
- Project integration – Suitable for projects such as Motor Speed Controller, LED Brightness Controller, Basic Synthesiser, and other designs where the following function is useful: Adjustable pulse-width modulation generator for experimenting with duty cycle and controlling compatible loads
