• Pawg Nextion Enhanced board.

Koj yuav tsum ua kom ntseeg tau tias koj siv lub zog sab nraud los ua lub zog rau ob lub cav stepper thiab Nextion Enhanced board. Stepper lub cev muaj zog tsav lub rooj tsavxwm nws tus kheej tau siv los ntawm Arduino yam tsis muaj teeb meem, tab sis qhov tseeb stepper lub cev muaj zog yuav xav tau lub zog hluav taws xob sab nraud. Pawg Thawj Coj Txhim Kho Ntxiv kuj xav tau lub zog siv hluav taws xob sab nraud vim tias nws xav tau tam sim no ntau dua li Arduino tuaj yeem muab kev nyab xeeb.

Nco tseg ntawm cov khoom siv hluav taws xob sab nraud siv. Kuv ua kom ntseeg tau tias kuv muaj lub zog loj txaus los tswj lub zog xav tau ntawm txoj haujlwm, thiab siv cov ntaub ntawv cuam tshuam los pab kuv txheeb xyuas cov kev xav tau no. Yog tias koj npaj yuav rov ua txoj haujlwm no, xyuas kom tseeb tias koj tau txiav txim siab tshwj xeeb lub zog xav tau ntawm koj lub cav, koj tus tsav tsheb thiab koj lub Nextion zaub. Arduino tuaj yeem tsuas yog muab 400mA ntawm tam sim no los ntawm 5V tus pin. Nrog txhua yam sib txuas, Kuv txhawb lub Nextion zaub, tom qab ntawd txhawb nqa Arduino. Stepper lub cev muaj zog pib tig tau txiav. Kuv siv thawj qhov kev sib hloov los hloov cov kev taw qhia thiab/lossis nrawm ntawm lub cev muaj zog. Thov nco ntsoov qhov siab tshaj plaws thiab yam tsawg kawg teeb tsa hauv Arduino code. Tom qab ntawd kuv siv lub khawm Tom ntej los dhia mus rau lub interface thib ob ntawm Nextion Enhanced zaub. Qhov thib ob interface zoo li piano. Thiab thaum kuv nias tus yuam sij ntawm lub tshuab ntaus piano, lub tshuab hloov pauv kom haum rau daim ntawv uas kuv nias.

Tam sim no koj ua tiav lawm.

Vam tias koj yuav nyiam nws
