Hauv qhov kev qhia no peb yuav pom cov kauj ruam yooj yim rau kev tsim cov cai Arduino board. Cov software siv yog KiCad rau kev tsim lub rooj tsavxwm thiab Arduino IDE rau kev tsim thiab thauj khoom ntawm firmware rau lub rooj tsavxwm.

Kauj ruam 1: Xav tau

Kev piav qhia ntawm cov txheej txheem xav tau.

- Tswj ntawm 2 DC lub cev muaj zog - 3 lub zog tswj lub zog - 4 servomotor tswj (PWM) - Kev tswj hwm lub zog: dual 12V thiab 5V fais fab mov. - Kev sib raug zoo nrog Arduino UNO thiab Mega header. - Lub taub hau rau ntxig rau cov txwv txwv thiab hloov pauv. - Kev siv ATMega2560 microcontroller - Kev sib raug zoo nrog Arduino system los ntawm kev thauj khoom Arduino bootloader ua ntej.

Kauj ruam 2: Schematic

Kev tsim cov phiaj xwm hluav taws xob los ntawm kev faib nws mus rau thaj chaw muaj txiaj ntsig xws li lub zog hluav taws xob, microcontroller subsystem, thiab lwm yam …

Thaum cov schematic tau tsim, khiav daim tshev.

Tom qab ntawd tsim cov ntaub ntawv cuam tshuam nrog schematic thiab siab dua txhua qhov BOM cov ntaub ntawv.

Kauj Ruam 3: PCB Tsim

Npaj cov khoom siv hauv thaj tsam xaiv rau PCB. (muab cov duab sib dhos ntawm nplooj 5-7-9 ntawm "DRIVEM.pdf").

Txaus siab rau qhov kev tso kawm, mus txuas ntxiv nrog kev nthuav tawm ntawm kev sib txuas ntawm cov khoom sib xyaw.

Txheeb xyuas cov cai tsim los ntawm lub tuam txhab uas yuav tsim cov pcb.

Kev tsim cov ntaub ntawv gerber kom xa mus rau lub tuam txhab.

Fablab Hauv Zos tuaj yeem muab kev nkag mus rau cov tshuab rau ua cov qauv.

Kauj Ruam 4: Pawg Rooj Sib Tham thiab Xeem

Thaum lub pcb thiab cov khoom tau txais, txuas ntxiv mus sib dhos lub rooj tsavxwm los ntawm kev siv cov khoom sib txuas.

Thaum sib sau ua ke, ua tiav nrog kev ntsuas hluav taws xob ntawm pawg thawj coj saib, piv txwv tias txuas ntxiv ntawm cov ciav hlau thiab cov khoom siv hluav taws xob raug ntawm cov khoom siv hluav taws xob.

Kauj Ruam 5: Siv Pawg Thawj Coj

Tam sim no tias pawg thawj coj tau sib sau ua ke thiab qhov ua haujlwm hluav taws xob tau raug txheeb xyuas, koj tuaj yeem txuas ntxiv nrog kev siv lub rooj tsavxwm ntawm Arduino IDE (ib zaug Arduino bootloader tau thauj khoom koj tuaj yeem hais txog kev ua haujlwm ntawm kev thauj khoom bootloader).
