What it does

Enables Arduino (or compatible) boards to control the Adafruit 1.8" SPI color LCD (ST7735 driver) and draw graphics, text, and images.

When to use it

•You need a low‑cost, 128×160 pixel color screen on a microcontroller prototype.
•You want to show status dashboards, sensor readouts, or simple UI on a handheld device.
•You are building a product that already uses Arduino/ESP32 hardware and needs a built‑in display.

Ready-to-paste prompt

```cpp
#include <Adafruit_GFX.h>
#include <Adafruit_ST7735.h>

#define TFT_CS   10
#define TFT_DC    9
#define TFT_RST   8

Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);

void setup() {
  tft.initR(INITR_BLACKTAB);      // initialize
  tft.setRotation(1);             // landscape
  tft.fillScreen(ST77XX_BLACK);
  tft.setTextColor(ST77XX_RED);
  tft.setTextSize(3);
  tft.setCursor(10, 30);
  tft.println("READY");
}

void loop() {
  // nothing – static screen
}
```

Heads up: The ST7735 driver has three hardware revisions (BLACKTAB, REDTAB, GREENTAB); using the wrong `initR()` constant will give a garbled or blank screen – double‑check the tab colour on your specific module before initializing.
