Kauj Ruam 1: Soldering 5 LM338T Arrary
Cov kab hluav taws xob hloov pauv no hloov cov theem nqis 16V laptop adapter muab hluav taws xob rau 5V LED muab hluav taws xob.
Kauj Ruam 2: Ua ntej Circuit Court rau Aux Signal Input
Ntawm sab laug sab tes ntawm lub khob cij yog TL071 op -amp Circuit Court uas suav thiab ua kom nrov aux input teeb liab uas yog los ntawm -1.25 txog 1.25V. Lub teeb liab tau hloov mus rau Arduino Vref 0 ~ 5V thaum lub sijhawm ua haujlwm ua ntej. Nws thaiv cov suab nrov uas tsim los ntawm Arduino analogread () kev ua haujlwm. LM7805 tus tswj hluav taws xob nyob hauv nruab nrab ntawm lub khob cij, uas hloov 9V roj teeb muab hluav taws xob rau 5V muab hluav taws xob rau Arduino. Aux-in jack nyob ntawm ntug sab xis, ua kom muaj kev sib txuas zoo nrog cov khoom siv rov ua dua. Lub aux splitter plam playback ntaus ntawv tso tawm lub teeb liab rau hauv ob. Ib qho yog muab rau tus hais lus, lwm tus muab rau Arduino.
Kauj Ruam 3: Arduino Pinout thiab LEDs
Nyob rau sab qis ntawm Aruidno lub rooj tsavxwm, Aruidno raug tsau rau hauv lub khob cij los ntawm cov xaim dawb ntawm sab laug, tus pin2 nyeem lub suab tso tawm los ntawm kev ua haujlwm ua ntej. Nyob rau sab saud, Arduino tau tsaws rau LM338 kab los ntawm lwm txoj xov hlau dawb, tus pin3 ntawm sab xis muab cov teeb liab txuas mus rau LED sawb.
