Lub hom phiaj ntawm txoj haujlwm no yog siv cov xim coj los ua kom lub teeb pom kev hmo ntuj qhib los ntawm lub suab ntsuas.
Kuv lub tswv yim yog kom tau txais lub teeb ci nyob ib puag ncig kuv lub txaj tab sis tsis muaj ntsia hlau, muab tshuaj txhuam lossis ntsaws dab tsi.
Yog li nws ua haujlwm ntawm NiMH AA roj teeb, nws tau ua los ntawm 3D luam ntawv thiab tau tsim los tso rau hauv pem teb, hauv qab koj lub txaj.
Kuv tshaj tawm 2 tus qauv: lub hli puv thiab ib nrab hli tsim.
Kauj Ruam 1: Cov Nqi Khoom
Electronics:
- WS2812 coj sawb (110cm ntev rau lub hli puv thiab 60 cm rau ib nrab hli)
- HC SR501 PIR tsab ntawv tsa suab sensor (1 rau ib nrab hli, 3 rau hli hli)
-
XH txuas (suab 2.54 hli)
crimping plier rau cov txuas no
- USB Serial adapter
- LDR sensor ua
- ib 4*AA roj teeb tuav
- 4 AA NiMH roj teeb
- ON/OFF hloov
- atmega328p (arduino programmed)
Electronics rau PCB:
Cheebtsam teev nyob rau hauv cov ntaub ntawv dav dawb hau
Mechanics:
- M3 * 10mm ntsia liaj qhov rooj
- M3 * 5mm ntsia liaj qhov rooj
- M3 tug
Tuam:
- Phom phom
- NiMH charger
Kauj ruam 2: Kev txawj
Txhawm rau ua qhov project koj yuav xav tau:
- lub tshuab luam ntawv 3D nrog 0.4mm lossis tsawg dua lub taub hau
-
siv Eagle kom xaj thiab ua PCB
Yog tias thaum twg koj tsis xav tias ua tau raws li qhov no, tiv tauj kuv, Kuv tuaj yeem muab PCB rau koj nrog txhua yam khoom siv xav tau
-
Cov txuj ci Arduino:
- nruab cov tsev qiv ntawv uas xav tau
- compile thiab rub tawm cov software
- xaiv qhov kev zov me nyuam atmega328p nrog arduino bootloader (lossis koj tuaj yeem nqa nws los ntawm pawg thawj tswj hwm arduino kom zam dhau cov kauj ruam no)
Kauj Ruam 3: Luam Ntawv 3D
Kuv tshaj tawm 2 tus qauv: tus qauv puv hli thiab ib nrab hli.
Kuv muab rau koj ntawm no:
- STL cov ntaub ntawv rau kev luam tawm ncaj qha
- Fusion 360 cov ntaub ntawv yog tias koj xav kho nws
Tsis luam ntawv:
- 0.3 hli txheej
- 0.4 hli extruder
- PLA
Kauj Ruam 4: Tus Tswj PCB
Kuv tus PCB tau ua nyob ib puag ncig atmega328p (nrog arduino bootloader programmed):
- Qhov chaw nres nkoj txuas tau txuas nrog 6 tus pinheader txuas, hauv lub hom phiaj txhawm rau ntsaws Serial-USB adapter
-
AQV20 yog photoMOS relay. Lub hom phiaj ntawm no yog hloov lub zog rau Led Sawb.
- Kuv muaj qee qhov AQV20 cov khoom hauv kuv cov khoom, tab sis kuv tau pom muaj tsis yooj yim mus nrhiav. Koj tuaj yeem nqa qhov sib npaug zoo li AQV21.
- Kuv muab lwm lub tswv yim txheej txheem uas siv MOSFET los hloov qhov AQV20 tab sis nws tseem tsis tau sim dua.
- FERRITE siv los lim lub suab nrov. Kuv tau pom thaum lub sijhawm kuv ntsuas uas PIR cov cim tuaj yeem ua rau qee zaum. Kuv tsis pom qhov laj thawj tseeb, tab sis kuv txiav txim siab ntxiv FERRITE, vim nws ua haujlwm zoo;-)
-
Lub rooj tsavxwm tau muab los ntawm 4 NiMH AA roj teeb = 4*1.2V = 4.8 V
- 4.8 V yog nominal voltage, dab tsi tsis txhais tau tias muaj dab tsi tseeb
- Thaum cov roj teeb tau them tas kuv ntsuas 5.1 V yam tsawg kawg nkaus, thaum tso tawm qhov hluav taws xob yuav poob
-
Qhov ntsuas hluav taws xob tau tswj hwm los ntawm kev ua haujlwm siab tau zoo hloov pauv MT3608
- Thaum tsis muaj nqi tam sim no tsawg dua 1mA
- T1 kho qhov hluav taws xob, nco ntsoov teeb T1 txog 15k kom tau 5V ntawm qhov tso tawm
Nws ua haujlwm li cas?
- PIR sensors tau txuas nrog PIR1/2/3 XH txuas.
- Thaum peb pib, atmega mus nrawm hauv hom pw tsaug zog. Kev siv tam sim no yog <1 mA.
- Thaum lub ntsuas ntsuas pom lub zog txav, nws xa +5V ntawm tus pin sib xws (4, 11, 13) thiab ua rau lub atmega tsaug zog.
- Tom qab ntawd lub atmega ua rau photoMOS relay, uas txhawb nqa Led Sawb (txuas nrog SIP XH). Cov ntaub ntawv raug xa mus rau ib kab BUS (tus pin 12 ntawm atmega).
- ronde 1.0 tau ua thiab sim, nws ua haujlwm zoo
- ronde 1.1 tau hloov lub photoMOS relay AQV20 los ntawm MOSFET transistor, nws tseem tsis tau sim dua
Kauj Ruam 5: LDR Assy
Thaum pib kuv tsis xav siv lub teeb pom kev zoo, tab sis qhov tseeb nws yog qhov muaj txiaj ntsig ntau dua los khaws roj teeb lub neej.
Yog li kuv tau siv Lub Teeb Pom Kev Tiv Thaiv nyob rau hauv koob nrog 10 Mohms resistor, muab nws tso rau hauv lub raj ntsws thiab ntxiv XH txuas.
VCC ---- | 10Mohms | ------- | LDR | ------- GND
Kuv siv tus PIR1 txuas lub ntsaws qhov LDR sib dhos. Rau ib nrab hli nws zoo, rau lub hli puv nws siv qhov chaw ntawm PIR sensor. Yog li kuv yuav tsum tau xaiv.
Kuv lub hom phiaj tsim lub rooj tsav xwm tshiab nrog txuas ntxiv rau lub teeb pom kev zoo. Rau yav tom ntej siv…
Kauj Ruam 6: Sib dhos
- Coj mus rhaub qhov nrog M3
- Solder LDR Assy
-
Ua XH cov txuas rau:
- PIR Sensors
- Roj Teeb Nrog
- Led Sawb
- Hwj chim ON/OFF hloov
- Solder Led Strip, txiav nws thiab muab tshuaj txhuam nws
- Siv rab yaj phom los nplaum PIR Sensor (s)
- Ntsia PCB nrog M3 - 5mm ntev
-
Txuas tag nrho cov txuas:
- Rau ib nrab hli: LDR ntawm PIR1 & PIR Sensor ntawm PIR2
- Rau lub hli puv: LDR ntawm PIR1 & PIR Sensors ntawm PIR2 thiab PIR3
Kauj ruam 7: Thauj khoom Software
Txuas lub USB-Serial interface raws li qhia hauv daim duab saum toj no. Saib xyuas kev taw qhia !! Yog tias thaum twg los xij koj ntsaws nws txoj kev thim rov qab nws yuav tsis ua rau lub rooj tsavxwm puas tsuaj, tab sis zoo dua kom zam nws.
Siv Arduino IDE txhawm rau rub tawm cov software sib xws.
Kuv siv cov tsev qiv ntawv sab nraud koj xav tau los nruab ua ntej:
- Adafruit_NeoPixel
- PinChangeInterrupt
Kuv sofware yog qhov yooj yim heev thiab kuv cia siab tias koj yuav tweak nws:
- Thaum lub hwj chim-up lub ledstrip yuav ntsais 3 zaug raws li cov lus txais tos.
- Tom qab ntawd lub micro-maub los mus rau hauv hom pw tsaug zog.
- Thaum pom cov lus tsa suab, nws tsa lub micro-controller thiab teeb lub teeb coj.
Ua si nrog software koj yuav tuaj yeem hloov xim, qeeb thiab lwm yam …
Txaus siab rau !!
