Lilo ọna LCD1602 pẹlu I2C Interface - Ẹkọ Arduino

Ẹkọ yii ṣe afihan bi a ṣe le sopọ ifihan LCD 1602 pẹlu Arduino nipa lilo modulu I2C, ti o jẹ ki asopọ rọrun ati mimọ ju asopọ afiwera ti aṣa lọ. Pẹlu awọn asopọ mẹrin nikan (VCC, GND, SDA, SCL), o le ṣakoso ifihan naa ni kikun ati ṣafihan ọrọ tabi data sensori ninu awọn iṣẹ akanṣe Arduino rẹ.

Gbogbo koodu ti a beere, awọn aworan asopọ, ati awọn ọna asopọ igbasilẹ ile-ikawe ni a pese ni isalẹ nkan yii.

Kini LCD1602 pẹlu I2C?

LCD1602 jẹ ifihan kikọ 16, ila meji ti a lo nigbagbogbo ninu awọn ọna ṣiṣe ifisinu. Ni deede, o nilo awọn pinni 6 si 10 lati ṣiṣẹ, ṣugbọn nipa fifi modulu I2C kun, o nilo awọn laini data meji nikan (SDA ati SCL) fun ibaraẹnisọrọ. Eyi dín awọn asopọ kuro ni pataki ati fi awọn pinni diẹ sii silẹ lori Arduino fun awọn ẹya miiran.

Asopọ LCD1602 si Arduino

Eyi ni bi o ṣe le sopọ LCD1602 rẹ pẹlu modulu I2C si Arduino Uno:

• VCC- 5V

• GND - GND

• SDA - A4

• SCL -A5

Apejuwe: LCD1602 ti a sopọ si Arduino nipasẹ I2C nipa lilo awọn okun mẹrin nikan.
