Kab lus no qhia txog kev siv tus lej lej lej keyboard thiab 16x2 I2C tus lej LCD tus qauv los tso cov ntaub ntawv rau ESP32. Txoj hauv kev no tuaj yeem siv los nkag thiab khaws cov ntaub ntawv pov thawj Wi-Fi thiab lwm yam ntaub ntawv mus thiab los ntawm ESP32.

Khoom siv

1 x ESP32 DEVKIT DOIT board

1 x Layad Circuits Kimat Alphanumeric Keyboard

1 x 9V/2A DC Fais Fab Khoom

1 x DC-DC Buck Converter LM2596

1 x 16x2 I2C Character LCD

2 x 1N5819 Schottky Diodes

Kauj Ruam 1: Kev Qhia Ua Haujlwm Video

Txoj haujlwm nthuav tawm hauv kab lus no tuaj yeem siv los ua ib qho kev qhia los tsim cov ntawv qhia zaub mov nyuaj raws Arduino daim ntawv thov.

Kauj Ruam 2: Cov Layad Circuits Alphanumeric Keyboard Module

Layad Circuits Alphanumeric keyboard module yog ua tiav thiab ua tiav cov keyboard daws teeb meem rau koj li Arduino cov phiaj xwm. Tus qauv suav nrog 96 tus qauv tsis muaj teeb meem tsis sib haum thiab ntau lub luag haujlwm ua haujlwm nrog cov lus tawm tswv yim. Tus qauv tuaj yeem txuas tau yooj yim rau ib qho khoom siv nrog UART lossis I2C interface. Tsis muaj qhov tshwj xeeb ntxiv rau kho vajtse tshwj xeeb (xws li PS2 lossis USB) xav tau. Qhov Layad Circuits Alphanumeric keyboard los hauv kev cog lus me me thiab qhov ua tau zoo nrog rau kaum kaum ntu uas tso cai rau nws kom yooj yim ua ke rau cov vaj huam sib luag thiab cov khoom sib dhos. Nws muaj qhov tshem tau yooj yim puag ncig lub hau tseem ceeb uas tuaj yeem hloov tau yooj yim lossis tej zaum sau npe yog xav tau. Nws muaj lub hwj chim tsim hluav taws xob LED qhia thiab ua haujlwm LED qhia. Layad Circuits Alphanumeric keyboard module muaj lub khoos phis tawj tsim ua haujlwm uas ua haujlwm txhua qib khoom siv hluav taws xob ua tiav ntawm cov yuam sij. Qhov no ua kom ntseeg tau cov lus teb keyboard nrawm heev thiab kev paub zoo tshaj plaws ntawm cov neeg siv.
