Kawm paub yuav ua lub suab paj nruas yooj yim siv UM66T suab paj nruag tshuab hluav taws xob IC.

Melody Generator yuav ua si Beethoven's Für Elise thaum cuam tshuam txij li nws siv UM66T-19L. Muaj ntau qhov sib txawv ntawm IC no, txhua tus teeb tsa los ua suab sib txawv.

Kauj Ruam 2: UM66T piav qhia

UM66T txwv tsis pub hu ua BT66T CMOS LSI tsim los rau kev siv suab paj nruag thiab muaj on-chip ROM uas muaj suab paj nruag qhib. Cov cuab yeej siv hluav taws xob tsawg heev (ib puag ncig 180mW) txij li nws tau tsim los siv txheej txheem CMOS. IC suav nrog inbuilt oscillation Circuit. Vim li no cov lus sib dhos suab paj nruag tuaj yeem tsim nrog tsuas yog ob peb yam ntxiv.

Kauj ruam 3: Ua haujlwm

Lub tswv yim ua rau ua rau lub tshuab hluav taws xob nrov nrov uas tig mus ua haujlwm sab nraud hais lus. Lub tshuab hluav taws xob lub suab nrov suav nrog oscillator, lub tshuab hluav taws xob nrawm, lub tshuab hluav taws xob Tempo thiab ROM. Cov oscillator zaus yog siv ua lub sijhawm rau suab nrov thiab ntaus cov tshuab hluav taws xob. Nws qhov raug cuam tshuam rau qhov ua tau zoo ntawm cov nkauj.

Kauj ruam 4: Circuit Schematic

5VDC lub zog hloov pauv tau siv los ua lub zog siv. Txij li thaum UM66T muaj qhov hluav taws xob siab tshaj plaws ntawm 4.5V, 100Ω resistor tau siv los txo cov khoom hluav taws xob kom haum rau 3.3V.

Thaum SPDT swb hloov pauv ON, UM66T tau tshwm sim thiab tsim lub suab paj nruag teeb liab uas pib los ntawm thawj qhov kev ceeb toom vim lub zog ntawm kev rov pib dua.

Ib lub transistor sab nraud ua kom nrov nrov thiab nws cov zis txuas nrog tus hais lus.

Kuv tsim lub rooj tsavxwm uas siv Txoj Kev Hlau.

Kuv drilled plaub qhov sib dhos hauv txhua lub ces kaum nrog txoj kab uas hla ntawm 3mm.

PCB loj yog 5cm X 5cm.

Kauj Ruam 6: Circuit Court Assembly

Muab thiab ua kom tag nrho cov khoom siv rau PCB. Muab ob npaug rau xyuas cov khoom nrog polarities. Thaum kawg, muab lub Hwj chim adapter thiab tus hais lus rau PCB.
