Sample Application

Vu meter, ST7735, microphone module and Arduino

(Vu meter connection, ST7735, Microphone Module and Arduino)

Code example for Arduino:

#include <Adafruit_GFX.h> // Adafruit Graphics Library
#include <Adafruit_ST7735.h> // Adafruit ST7735 Library

// Connection Pins
#define TFT_RST 8 // Reset pin
#define TFT_CS 9 // Chip select pin
#define TFT_DC 10 // Data/Command pin

// Specify the size of the screen (160x128 pixels)
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);

void setup(void) {
   tft.initR(INITR_BLACKTAB); // Initialize the screen
   tft.fillScreen(ST7735_BLACK); // Fill the screen with black
   tft.setRotation(1); // Set the orientation of the screen (1 or 3 available)

   tft.setTextColor(ST7735_WHITE); // Set the text color to white
   tft.setTextSize(2); // Set text size (1, 2, 3 available)
}

void loop() {
   tft.setCursor(20, 30); // Set where to start the text on the screen (x, y)
   tft.println("Hello, World!"); //Print the text
   delay(2000); //wait 2 seconds
   tft.fillScreen(ST7735_BLACK); //clear screen
   delay(1000); //wait 1 second
}
