The contrast is the weakest when connected to the positive power supply, and the contrast is the highest when the power supply is grounded. When the contrast is too high, it will produce \"ghosting\". When using, you can adjust the contrast through a 10K potentiometer\u003cbr\u003ePin 4: RS is the register selection, the data register is selected at high level, and the instruction register is selected at low level.\u003cbr\u003ePin 5: R\/W is the read and write signal line, read operation at high level, and write operation at low level. When RS and RW are both low level, the command or display address can be written. When RS is low level and RW is high level, the busy signal can be read. When RS is high level and RW is low level, data can be written.\u003cbr\u003ePin 6: The E end is the enable end.

For example, the code for the uppercase English letter \"A\" is 01000001B (41H). When displaying, the module displays the dot matrix characters in the address 41H, and we can see the letter \"A\" \"\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cimg style=\"width:100%;height:auto\" width=\"100%\" height=\"auto\" src=\"https:\/\/ae01.alicdn.com\/kf\/S08b9132d616d48fbae834501bf0235417.jpg\" slate-data-type=\"image\"\u003e \u003cimg style=\"width:100%;height:auto\" width=\"100%\" height=\"auto\" src=\"https:\/\/ae01.alicdn.com\/kf\/Sa70fce9e3fb74b178431dd563be1a21bL.jpg\" slate-data-type=\"image\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cbr\u003e","brand":"Yoeruyo","offers":[{"title":"1602A blue -with IIC","offer_id":55420414296363,"sku":"14:10#1602A blue -with IIC","price":14.99,"currency_code":"USD","in_stock":true},{"title":"IIC adapter board","offer_id":55420414329131,"sku":"14:350850#IIC adapter board","price":6.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/S4264a1811d954d5b95dbf052fa85fd72s.webp?v=1788505608","url":"https:\/\/yoeruyo.com\/products\/1602-lcd-module-16x2-hd44780-for-arduino-character-5v-lcd-display-iic-i2c-serial-pcf8574-interface-adapter-plate-module-diy-kit","provider":"Yoeruyo","version":"1.0","type":"link"}
