This is the sound scale that I would like to achieve. However, I would like to do without the potentiometer and program an increasing frequency scale to occur automatically. Any ideas of how to do this?

Two years later... Very interesting! Could you output to a larger speaker rather than the Buzzer? To get the lower frequency's?

I need a unit that has a a keypad entry to punch in frequencies from 20 hz to 2000 hz at 0.1 hz resolution, and display would prefereably be the 128x64 oled display, and number keypad with decimal. Thanks. Please send bid to libertathiest@gmail.com

Hi THis is Cool.. I am not a Programmer. but I had a Favorite Horn thats not available now.. https://www.youtube.com/watch?v=TcLO76OQLq8 I Wished if ESP-12 D1 Mini V2 Board ESP-12F ESP8266 WEMOS ESP8266 D1 Pro mini-16 https://robu.in/product/d1-tf-module-tf-card-expansion-board/ Espressif System’s ESP8266 WROOM-02 Wi-Fi module (with 4Mb flash) CJMCU-4051 74HC4051 8 Channel Analog Multiplexer/Demultiplexer Breakout Board for Arduino https://robu.in/product/cjmcu-4051-74hc4051-8-channel-analog-multiplexerdemultiplexer-sensor-module-breakout-board-arduino/ can be used to Generate HIGH TONE : 500Hz MID TONE : 480Hz LOW TONE : 420Hz and be able to Adjust the HT MT and LT Frequencies Switch to 2 tone or 3 tone Change the Fading delay Change the Delay Time Change the Pattern Change the Waveform Width Change Saw to Triangle Assign HT MT and LT to any of the Parameters through the Mobile and set a Default for ever unless we select. with https://robu.in/product/waveshare-pico-1-14-inch-lcd-display-module/ i know this can be done but Im not a Programmer. the 3 d1 analogue outputs can be sent to a 60w Amplifier i am a Power Circuits Designer im good at IGBT type Power Circuits.

And now I want to add blinking LED's to match the frequency!
