MicroDot yog lub tsev tsim Alexa 'khawm' tsim los txuas nrog LattePanda lossis Raspberry Pi, nrog Alexa Sample App teeb tsa. Nws yog tus hais lus me me nrog LED's thiab kov/hais kom ua, thiab yog qhov zoo rau siv ntawm lub desktop lossis hauv tsheb.

*LattePanda rau txoj haujlwm no tau ua siab zoo muab los ntawm DFRobot

Kauj Ruam 1: Txheej Txheem Txheej Txheem

LAWV PANDA

LattePanda yog qhov me me (hais txog qhov loj me ntawm Raspberry Pi) Windows 10 khoos phis tawj nrog Arduino built-in rau cuam tshuam rau lub ntiaj teb tiag. Nws yog qhov zoo heev - thiab yog qhov hloov pauv tau zoo rau Raspberry Pi - tshwj xeeb tshaj yog tias koj (zoo li kuv) muaj teeb meem kom tau tuav nrog Linux.

Kuv tau teeb tsa Alexa Sample App mus rau Panda, thiab tau siv kuv tus kheej lub suab-lo lus cav raws li Windows built-in hais lus paub SDK.

MICRODOT

MicroDot suav nrog lub tshuab ua kom me me thiab hais lus nrog kov-rhaub grill thiab xiav/dawb LED teeb. MicroDot tau xub tsim los muab tso rau ntawm kuv lub tsheb kom muab kuv lub tsheb Alexa daws (los ua ke nrog kuv qhov haujlwm yav dhau los-Alexa-enabled tsheb tso suab). Ntxiv rau qhov muaj qhov xaiv-lo lus xaiv, Kuv xav kov-ua kom zoo vim tias Alexa yuav muaj lub sijhawm nyuaj hnov kuv cov lus tsa suab thaum lub suab paj nruag nrov nrov! (Thaum ua haujlwm lawm, Panda yuav xa lub teeb liab mus rau lub tso suab kom tig lub suab qis thaum Alexa tab tom mloog/hais lus).

RASPBERRY PI

Rau cov neeg uas paub zoo dua hauv "Raspberry Pi", Kuv tau piav qhia qhov kawg ntawm Cov Lus Qhia no yuav ua li cas cuam tshuam MicroDot nrog Rapsberry Pi 3.

Kauj Ruam 2: MicroDot Circuit

XEEM

6 x 220R SMD Resistors2 x 470R SMD Resistors1 x 10uF SMD Capacitor1 x TTP223 Touch Sensor Module (https://www.ebay.com/itm/192097635565)1 x PAM8403 3W Amplifier Module (https://www.ebay.com/ itm/221895096190) 1 x 10K Ib Leeg Tawm Thumb Potentiometer (https://www.ebay.com/itm/401105807680)1 x 50pF Ceramic Capacitor3 x 3mm Blue LEDs3 x 3mm White LEDs1 x 1.7inch 4ohm 3W Speaker1 x Thin Black Cable los ntawm Pob Ntseg Pob Ntseg 1 x Nyias Dub 1m USB Txuas Txuas*

Kev tsim kho

MicroDot PCB tau ua los ntawm cov hlau ntawm cov txheej txheem toner ntawm 0.8mm tuab ib leeg -lub rooj tsavxwm - ntawm qhov tuab nws tuaj yeem txiav ntxhib kom zoo nrog cov txiab ntse thiab tom qab ntawd yooj yim xa mus rau cov duab. Mount tag nrho cov ntu ntu ntu ua ntej.

Cov xaim yuav tsum tau txuas nrog lub ntsej muag kov ntawm lub sensor, yog li thaj chaw me me yuav tsum tau muab pov tseg kom yaj rau. Kuv pom tias hauv nws hom nyoos, lub ntsuas tau nrawm heev - nws ua haujlwm tau zoo, tab sis ib zaug nws tau teeb tsa hauv lub thawv ntawv nws feem ntau tsis raug qhov tshwm sim vim nws nyob ze rau tus hais lus hlau. Kuv tsaws cov hlau hais lus - uas tau pab me ntsis, tab sis kuv yuav tsum thaum kawg xa mus rau cov ntawv teev npe.

TTP223 cov ntawv teev tseg hais tias koj tuaj yeem hloov kho qhov rhiab heev los ntawm kev tso lub capacitor (0 txog 50pf) nruab nrab ntawm qhov kov lub ntsej muag thiab hauv av. Lub sensor ua haujlwm zoo nrog 50pf capacitor. Koj tuaj yeem pom qhov kev tso kawm ntawm no hauv daim duab ntawm ntu tom ntej.

Ob txoj hlua txuas tau siv los txuas MicroDot rau Panda:- ib txoj hlua dub dub los ntawm ib khub qub pob ntseg los txuas lub suab- ib qho USB cable nyias tau siv los txuas rau GPIO (kov sensor/LEDs). Koj yuav xav tau ib lub cable nrog 6 qhov sib txuas sib txuas (5 sab hauv + ntaub thaiv npog). *Ceev faj tias qee qhov pheej yig USB cables tsis muaj qhov sib cais hauv av-tus pin/ntaub thaiv npog, lossis ob qho no tuaj yeem txuas nrog sab hauv (txheeb xyuas qhov no ua ntej txiav koj lub xov tooj los ntawm kev ua kom ntseeg tau tias muaj txuas ntxiv ntawm cov hlau sab nraud ntawm txiv neej thiab poj niam) ntsaws, thiab tias tsis muaj qhov txuas ntxiv ntawm tus pin hauv av thiab cov hlau sab nrauv).

Siv USB txuas txuas: liab =+5v, ntaub thaiv npog = GND, dub = kov sensor, dawb = dawb LEDs, ntsuab = xiav LEDs. thiab khaws cov ntsaws thiab txiav ib ntu ntev thiab ib ntu luv (hais txog 200mm) ntu, thiab ntsaws ob qhov kawg ntawm txoj hlua ua ke. Txoj hauv kev no lub tsev tshem tawm tau. Tsuas yog xyuas kom tseeb tias koj tsis tau ntsaws cov cuab yeej USB tiag tiag rau hauv nws, lossis ntsaws nws rau hauv USB chaw nres nkoj ib txwm muaj!

Kauj Ruam 3: Kev Siv MicroDot

3D luam tawm XEEM

Muaj plaub ntu 3D luam tawm hauv cov ntawv zip txuas: 1. Lub plhaub MicroDot loj - luam tawm hauv PLA2 dub. MicroDot puag - luam tawm hauv dub PLA3. Lub nplhaib LED - luam tawm hauv PLA dawb (pom tseeb lossis zoo dua yuav zoo dua los pab nthuav lub teeb kom zoo dua qub) 4. PCB spacer - txhua xim - sib xyaw ntawm tus hais lus thiab PCB.

M2 ntsia liaj qhov rooj thiab txiv ntseej tau siv los ntsaws lub hauv paus rau lub plhaub. Peb M2 ntsia liaj qhov rooj yuav tsum tau yaj mus rau hauv lub qhov nyob rau sab hauv ntawm lub plhaub. Cov no yog cov me me, thiab koj yuav xav tau '' solder '' lawv nyob rau hauv qhov chaw nrog qee cov ntsiab lus ntxiv.

LED ARRAY

Cov dawb thiab xiav LEDs tau teeb tsa hauv kab sib txawv raws li qhia hauv daim duab. Cov coj yog khoov mus rau 90 degrees tiv thaiv hauv qab ntawm LED thiab cov hlau lead tau yaj rau hauv lub nplhaib nrog cov hlau kub kub (nco ntsoov qhov tsis sib xws ntawm no). Cov hauv qab ntawm LEDs tau sau cia kom lawv tiaj tus rau ntawm lub nplhaib.

Cov cathodes ntawm LED's txhua tus tau txuas ua ke nrog lub nplhaib ntawm cov hlau thiab cov no txuas rau qis-feem ntau tus pin ntawm lub taub hau. Lwm tus pin ntawm lub taub hau yuav tsum yog hloov xiav/dawb rau txhua tus neeg LED

Muab nws tso ua ke

Cov hniav nyiaj hniav kub tau txiav los ntawm lub desktop ntawv tuav (duab) nrog xaim xaim txuas rau ib sab. Qhov no tau muab tso rau hauv lub plhaub ua ntej, tom qab ntawd cov kab LED (qhov no yuav tsum tau muab ntxig rau ntawm lub kaum sab xis raws li qhia, nrog lub qhov txuas ua ke nrog ib qho ntawm cov ntsia hlau tshaj tawm). Tus hais lus yog tom ntej (tso qee daim kab xev nyias nyob ib puag ncig sab saum toj kom tiv thaiv nws los ntawm ntug ntawm PCB). Tom qab ntawd tus spacer, thiab PCB tsuas yog zaum saum. Ntsia lub hauv paus kom nws tag nrho ua ke.

Thaum ntsaws cov kab hluav taws xob txuas rau hauv LattePanda, Kuv pom tias kuv yuav tsum tau siv lub suab lim hauv av (https://www.ebay.com/itm/371801191297) kom tau lub suab zoo. Nco ntsoov tias hauv cov duab kuv siv lub suab tawm ntawm kuv lub HDMI-VGA video adapter, tab sis nws zoo siv lub suab tso tawm ntawm lub rooj.

Koj tseem yuav xav tau lub usb microphone (https://www.ebay.com/itm/332148968227).
