Kuv xav tau tus pas ntsuas kub hauv chaw ua haujlwm. Ntau dua li yuav ib qho kuv siv Adafruit Circuit Playground Express los ua ib qho. Nws yog digital/quasi-analog. Cov xim qhia txog qhov kub thiab txias (ntsuab ntawm no - rau 70's), nrog tus lej NeoPixels qhia tus lej (yog li lub sijhawm ua haujlwm pom ntawm no yog 75). Thaum nws tsaus ntuj cov zaub tso tawm.

Khoom siv

Adafruit Circuit Playground Express

3D Tshuab Luam Ntawv (Kuv siv PLA)

M3 x 8 screws (x4) thiab M3 txiv ntoo (x4)

Daim kab xev sib nqus (https://www.amazon.com/gp/product/B073519752)

Kauj ruam 1: Mount

Kuv xav tau qee qhov airflow rov qab vim kuv tsis paub tseeb tias pawg thawj coj tau sov yuav cuam tshuam rau kev nyeem ntawv. Lub roob tau tsim hauv Fusion 360. Qauv muaj nyob rau ntawm Thingiverse (https://www.thingiverse.com/thing:3659694). Ntau dua li sim khaws cov ntsia hlau xov hauv PLA, Kuv muab qhov chaw tso M3 txiv ntoo rau hauv M3 screws.

Kauj Ruam 2: Txoj Haujlwm

Cov cai yog Circuit Python, siv Adafruit cov tsev qiv ntawv rau CPE. Cov cai tam sim no muaj nyob ntawm GitHub (https://github.com/KFW/CPE_thermometer) tab sis nws yog qhov yooj yim.

Kauj ruam 3: Mount

Kuv tau siv qee daim kab xev sib nqus nyob tom qab txhawm rau txhim kho nws.
