Common Applications

• Weather station display — BME280 + OLED + ESP32 showing temperature, humidity, pressure
• Digital clock — DS3231 RTC + TM1637 4-digit display + Arduino
• Sensor dashboard — 2.4" TFT + multiple sensors + Raspberry Pi or ESP32
• Robotic arm control — PCA9685 servo driver + 6 MG996R servos + Arduino Mega
• Smart energy monitor — ACS712 + 16×2 LCD + ESP32 with WiFi upload

How to Choose a Display

1. Content type — text/numbers → LCD 16×2; icons/graphs → OLED; full colour → TFT
2. Interface — I2C for fewer pins; SPI for faster refresh; parallel for fastest (but most pins)
3. Power budget — OLED draws ~20mA at full brightness; e-ink draws near zero in standby
4. Size — 0.96" OLED for compact builds; 3.5" TFT for touchscreen HMI panels
