Tutorial: How to use 3.2 inch Touch TFT LCD with SD Card slot

This high-resolution touch TFT LCD screen is ideal for Arduino projects requiring interactive and detailed data display. Perfect for beginners and intermediate makers.

What you need

• Arduino Uno or compatible
• USB micro-B cable
• SD card (check the datasheet)
• lab tools

Steps

1. Connect the display to the Arduino USB connector using a micro-USB cable.
2. Check the display voltage and configure it according to the requirements (5V or 3.3V).
3. Install the necessary libraries to manage the display and the SD card on the Arduino IDE.
4. Write the example sketch provided by the manufacturer to test the display features.
5. Upload the sketch to the microcontroller.
6. Verify that the display turns on correctly and displays the shown data.
7. Configure the read/write from the SD card (check the datasheet).
8. Test the interactivity of the touch screen.

Example code

// Includi le librerie necessarie
#include <TFT_eSPI.h>
// Definizione delle variabili e configurazione del display
TFT_eSPI tft = TFT_eSPI();
tft.initLCD(true); // Configura il display
// Aggiungi qui lo sketch per testare la funzionalità della SD card

Mini project

Create a small dashboard that displays data from the DHT11 temperature and humidity sensor, stored on an SD card.

Common mistakes

• Incorrect display voltage connection
• Misalignment of installed libraries
• Incorrect SD card configuration
• Touch Screen Interaction Issues

Recommended accessories

• DHT11 Sensor
• 4GB SD Card
• 3D Print Case for the Project
• LiPo Battery with USB Charger
