2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29
Rau kuv Qhov Kev Xeem Kawg Kawg, Kuv tsim tus tswj LED siv lub zog ntsuas. Lub hom phiaj ntawm txoj haujlwm no yog siv lub zog ntsuas los tswj cov LEDs uas nyob. Thaum lub hwj chim ntsuas hluav taws xob tig mus rau lub moos, nws ua rau cov LEDs ploj mus kom thawj LED tau ci tshaj plaws, qhov thib ob yog dimmer me ntsis, qhov thib peb tsis tshua pom, thiab qhov thib plaub thiab thib tsib raug tshem tawm tag nrho.
Nov yog cov npe ntawm cov khoom siv:
- LEDs (x5) - Kuv siv 5 xim sib txawv.
- 220 Ohm Resistors (x5)
- Jumper Hlau (x10)
- Arduino Ib
- Cov qhob cij
Kauj Ruam 1: Ntxiv cov LEDs
Nov yog qhov uas kuv tau ntxiv cov LEDs rau ntawm lub khob cij thiab tom qab ntawd mus rau Arduino. Kuv siv 5 xim sib txawv rau LEDs rau kev zoo nkauj.
1. Ua ntej, txuas cov LEDs mus rau lub khob cij.
2. Txuas qhov luv luv ntawm LEDs rau hauv av tsheb nqaj hlau.
3. Txuas qhov ntev mus rau Arduino siv 220 (ohm) Resistors.
4. Txuas cov LEDs rau tus pin 13, 12, 11, 10, thiab 9 ntawm Arduino.
5. Siv lub jumper hlau, txuas cov tsheb nqaj hlau hauv av mus rau GND ntawm Arduino.
Kauj Ruam 2: Ntxiv Potentiometer
Nov yog qhov kuv txuas lub hwj chim rau Arduino.
1. Muab lub potentiometer tso rau ntawm lub khob cij.
2. Txuas tus pin sab laug ntawm lub hwjchim mus rau Txoj Kev tsheb nqaj hlau ntawm lub khob cij.
3. Txuas tus pin sab xis ntawm lub hwj chim rau hauv txoj kev tsheb nqaj hlau ntawm lub khob cij.
4. Txuas tus pin nruab nrab nruab nrab mus rau A5 Analog chaw nres nkoj ntawm Arduino.
5. Siv lub jumper hlau, txuas Cov Hluav Taws Xob mus rau 5V chaw nres nkoj ntawm Arduino.
Kauj ruam 3: Upload Code
Nov yog cov cai uas yuav ua haujlwm qhov program. Rub nws mus rau Arduino Uno thiab txaus siab rau!

Tswj LED Brightness Nrog Potentiometer Nrog Arduino: 3 Kauj Ruam
Tswj LED Brightness Nrog Potentiometer Nrog Arduino: Hauv txoj haujlwm no, peb yuav tswj qhov ci ntawm LED siv qhov sib txawv tsis kam muab los ntawm potentiometer. Nov yog txoj haujlwm yooj yim heev rau tus pib tab sis nws yuav qhia koj ntau yam txog potentiometer thiab LED ua haujlwm uas yuav tsum tau ua kom muaj kev tshaj tawm
Tsim Koj Tus Kheej BiQuad 4G Antenna Nrog Kev Xeem Ceev: 7 Kauj Ruam (nrog Duab)
Ua Koj Tus Kheej Tus Kheej BiQuad 4G Kuaj Nrog Kev Xeem Ceev: Hauv cov lus qhia no kuv yuav mus qhia koj li cas kuv tau ua BiQuad 4G kav hlau txais xov. Teeb liab txais tos tsis zoo ntawm kuv lub tsev vim muaj roob nyob ib puag ncig kuv lub tsev. Lub teeb liab pej thuam yog 4.5km deb ntawm tsev. Hauv koog tsev kawm ntawv Colombo kuv tus muab kev pabcuam muab 20mbps nrawm. mas m
ESP8266 RGB LED Sawb WIFI Tswj - NODEMCU Raws li IR Chaw Taws Teeb rau Led Sawb Tswj Hauv Wifi - RGB LED Sawb Smartphone Tswj: 4 Cov Kauj Ruam
ESP8266 RGB LED Sawb WIFI Tswj | NODEMCU Raws li IR Chaw Taws Teeb rau Led Sawb Tswj Hauv Wifi | RGB LED Sawb Smartphone Tswj: Nyob zoo cov neeg hauv qhov kev qhia no peb yuav kawm paub siv nodemcu lossis esp8266 li IR chaw taws teeb los tswj RGB LED sawb thiab Nodemcu yuav raug tswj los ntawm smartphone dhau wifi. Yog li hauv paus koj tuaj yeem tswj RGB LED Sawb nrog koj lub xov tooj
Huab cua-chaw nres tsheb Nrog Arduino, BME280 & Zaub rau Pom Kev Pom Zoo Hauv 1-2 Hnub Xeem: 3 Kauj Ruam (nrog Duab)
Huab cua-chaw nres tsheb Nrog Arduino, BME280 & Zaub rau Pom Kev Pom Zoo Hauv 1-2 Hnub Xeem: Nyob Zoo! Ntawm no ntawm cov lus qhia qhia txog huab cua tau twb tau qhia lawm. Lawv qhia txog huab cua tam sim no, qhov kub thiab txias. Dab tsi lawv tsis muaj txog tam sim no yog kev nthuav qhia ntawm chav kawm hauv 1-2 hnub dhau los. Cov txheej txheem no yuav muaj lub
