Video: Yuav Ua Li Cas VU Meter Siv Arduino: 3 Cov Kauj Ruam (nrog Duab)
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29
Lub VU meter yog lub ntim ntim (VU) 'meter' lossis tus qauv ntsuas qhov ntsuas (SVI) yog cov khoom siv uas pom qhov sawv cev ntawm qib teeb liab hauv cov khoom siv suab. Nws yog siv los pom lub teeb liab Analog.
Tam sim no kuv yuav qhia yuav ua li cas thiaj ua VU meter siv Arduino nrog cov lej tsawg dua.
Mus ntsib qhov kev qhia no kom paub ntau ntxiv.
Pib..
Kauj Ruam 1: Cov Cheeb Tsam Yuav Tsum Tau
Arduino Uno (nrog Adapter lossis roj teeb 9V) [DigiKey]
Resistors - 100 Ohm (x11) [DigiKey]
LEDs (Txawv Xim) - 11
Hookup hlau - 1.5 txog 2 meters [DigiKey]
3.5 hli Audio Jack -1 [DigiKey]
PCB -1 [DigiKey]
Kauj ruam 2: Kev sib hloov
Ntxig LEDs rau hauv PCB xws li txhua lub dav hlau zoo nyob hauv ib sab.
Ntxig Resistors rau hauv PCB hauv kab nrog Lub davhlau ya nyob twg zoo ntawm LEDs.
Cov kab hluav taws xob txuas rau 3.5mm audio jack.
Solder tag nrho cov khoom raws li Circuit Court.
Siv Hookup xaim los txuas rau hauv kab nrog resistor rau Arduino digital pins.
Upload cov cai rau hauv arduino.
Ntxig ib lub xov hlau ntawm lub suab ntawm A0 thiab lwm qhov rau GND.
Ntawm no qhov kev sib tw ua tiav
Ntxig Suab Jack rau txhua lub suab thiab ntsuas qhov Circuit.
Kauj Ruam 3: Kev Tsim Kho thiab Kev Xeem
Xav tias dawb los tawm tswv yim.
