Txoj haujlwm no hu ua Larson Loop uas tau tshoov siab los ntawm lub cuab yeej hu ua Larson Scanner. Qhov tswv yim yog tias koj muaj cov lej LED ntau nyob hauv lub voj uas pom lub teeb los ntawm LEDs zoo li nws mus hauv lub voj. Ib qho ntxiv, lub zog ntsuas tau siv los hloov cov kev taw qhia thiab nrawm ntawm Larson lub voj ib yam
Khoom siv
Rau qhov haujlwm no, nws xav tau:
- 8 1k ohms resistors
- 15-ish jumper xov hlau
- Arduino Mega (lossis ib qho Arduino nrog 8+ PWM pins)
- 10k ohm potentiometer
- 8 LEDs
Kauj ruam 1: +5V thiab GND
Thawj kauj ruam yog txhawm rau txuas hauv av (GND) thiab lub zog (+5V) los ntawm Arduino mus rau lub khob cij. GND rau kab ntawv nrog qhov tsis zoo kos npe rau ntawm lub khob cij. +5V rau kab ntawv nrog lub cim zoo ntawm daim ntawv qhia zaub mov.
Kauj Ruam 2: Txuas cov LEDs thiab Cov Tiv Thaiv
Cov kauj ruam tom ntej yog teeb tsa cov LEDs thiab cov neeg tawm tsam mus rau lub khob cij. Muaj txhua tus tiv thaiv txuas rau tus pin cathode lossis tus pin luv ntawm LED thiab rau GND ib yam li hauv daim duab. Tom qab ntawd txuas lub jumper cable rau txhua tus pin anode lossis tus pin ntev dua ntawm LED thiab mus rau PWM tus pin ib yam li hauv daim duab.
Nco ntsoov, tias kuv siv Arduino Mega uas muaj PWM pins rau tus pin 2-13 thiab tsis yog Arduino Uno
Kauj Ruam 3: Txuas lub Potentiometer
Tom qab ntawd, txuas lub hwj chim rau lub khob cij. Muaj +5V mus rau ib qho kawg ntawm lub hwj chim thiab muaj GND mus rau lwm qhov kawg ntawm lub hwj chim. Tom qab ntawd txuas cov xaim los ntawm tus pin nruab nrab ntawm lub hwj chim rau A0 tus pin ntawm Arduino.
Kauj ruam 4: Arduino Code
Luam cov cai rau koj Arduino software. Cov lus hais ntawm txoj cai piav qhia nws ua haujlwm raws kab.
Kauj ruam 5: Xeem & Ua tiav
Thaum koj ua tiav teeb tsa koj qhov program thiab Circuit. Khiav cov cai. Koj yuav tsum pom tias LEDs yuav nyob hauv lub voj. Koj tuaj yeem hloov nws cov kev taw qhia thiab nrawm los ntawm kev kho lub pob qhov rooj ntawm lub zog.
