or
- DROK PWM signal generator operating voltage range is DC 3.3-30V, adjustable pwm frequency range is 1Hz-150kHz, adjustable duty ratio range is 0%-100%.
- Application: it can be used as a square wave signal generator, generate square wave signal for experimental development; generate square wave signal to control the motor driver; generate adjustable pulse for MCU; generate adjustable pulse to control the relevant circuit (PWM dimming speed application etc).
- High Frequency Resolution: frequency in range 1Hz~999Hz, display resolution is 1Hz; range 1.00kHz~9.99kHz, display resolution is 0.01kHz; range 10.0kHz~99.9kHz, display resolution is 0.1kHz; range 1kHz~150kHz, display resolution is 1kHz.
- TTL Level Communication: the frequency meter is designed with single-chip TTL level communication, communication standard is 9600 bps.
- LCD Display: the blue LCD clearly displays frequency and duty ratio, PWM output can set frequency and duty ratio independently.

If you're willing to try some DIY/soldering then something like This or This will do the trick. It would need at least the LEDs, some wiring, and a resistor as well to make it work. It would be fully adjustable though to get the perfect effect.
