We are here again with a project you will like. If you like listening to music and enjoy the visuality, this project is for you. DIGITAL CLOCK MUSIC SPECTRUM ELECTRONIC KIT WITH TEMPERATURE DISPLAY.

This is an electronic kit. When you complete the project you will not only have a music spectrum, but also a digital clock and thermometer.

Kit function:

A suitable sound source near it can switch to spectrum, can be switched to the clock (12/24 hours) and temperature (degrees Celsius and Fahrenheit) display, the spectrum sensitivity have 3 levels adjustable, 3 kinds of display mode optional.

Spectrum type: no need to connect to the audio cable, just close to the sound source.

Color classification: colorful, red, green, blue, white optional.

Step 1: ​The Working Principle

The display screen is made up of 160 LEDs components of the 10*16 dot matrix.Driven by the MCU and LED driver chip.

When the display signal spectrum, voice chip on the microphone module output sampling, get the amplitude of each frequency point by FFT, and display to the dot matrix screen. Because the sound is constantly changing, so the calculated amplitude are constantly changing, so you can see a change with the sound pattern.

When the clock is displayed, the MCU reads the time in the clock chip and displays it in the dot matrix screen.

When the display temperature, MCU read voltage of thermistor is converted into temperature, and display to the dot matrix screen.

Step 3:

We will go step by step;

Step 4: LED Assembling

We are assembling LEDs to PCB. You can follow this order for assembling.

Red - Red - Blue - Blue - Green - Green- White - White - Red - Red - Blue - Blue - Green - Green - White- White

Step 5: Resistors Assembling

Next step will resistors... We are using 470 ohm and 47K resistors.

Step 6: Other Components Assembling

You will see on pics others. We are assembling Chips, capacitors, keys and others. And also you can watch on video with timestemp : 4:33

Step 7: Boxing

Now we have a electronic card. And next will be boxing for it.

Step 8: TESTING AND SHOWTIME

We tested our project. And as you see , working good. If you click video, will start " SHOWTIME"
