Ing artikel dina iki aku pengin nuduhake karo sampeyan proyek anyar. Wektu iki saklar tutul karo panel kaca. Piranti kasebut kompak, ukurane 42x42mm (panel kaca standar duwe dimensi 80x80mm). Sajarah piranti iki wiwit dangu, kira-kira setahun kepungkur.
Opsi pisanan ana ing mikrokontroler atmega328, nanging pungkasane rampung karo mikrokontroler nRF52832.
Bagian tutul piranti kasebut nganggo chip TTP223. Loro sensor dilayani dening siji interupsi. Didhukung dening baterei CR2477, liwat konverter ngedongkrak ing chip TPS610981 | .
Piranti kasebut nindakake sirkuit mateni kanthi nggunakake transistor efek lapangan. Sawise mencet tombol, mikrokontroler dhewe nyegat kontrol daya lan banjur tombol bisa digunakake kanggo mode layanan (ing kasusku, iki dipasangake karo piranti liyane, mateni daya lan ngreset setelan pabrik).
Ana 2 rgb LED kanggo nuduhake negara lan mode layanan. A emitor piezo uga wis ditambahake kanggo simulasi klik nalika nutul tombol tutul lan pratondo swara saka mode layanan. LED lan emitor piezo bisa diuripake lan dipateni miturut kawicaksanan pangguna. Iki ditindakake liwat pengontrol omah sing cerdas kanthi ngirim perintah menyang sensor teknis; pangguna uga bisa ngganti interval kanggo ngirim daya baterei lan level sinyal uga liwat pengontrol omah sing cerdas. Ing kasusku iku .
Konsumsi ing mode transmisi yaiku 7mA (250kbit, 10ms), konsumsi nalika turu 40Β΅A, konsumsi ing kahanan mati kurang saka 1Β΅A (= konsumsi konverter boost ing mode "idle"). Rx, tx, konektor swd kanggo program kasedhiya. Konektor miniatur 2x3p kanthi pitch 1.27 digunakake. A adaptor khusus digawe kanggo program.
Kaya biasane, operasi piranti kasebut adhedhasar protokol . Ngalih tutul iki ngrancang digunakake ing sistem kontrol wuta roller. Nanging umume, aplikasi kasebut mung diwatesi dening imajinasi sampeyan. Contone, anakku (7 taun) wis nggawe 3 pesenan kanggo versi switch: kanggo nguripake lan mateni lampu ing jamban karo bathtub (bakal dipasang kurang saka lantai), kanggo nguripake lampu ing a koridor dawa lan peteng nalika lelungan menyang jamban karo bathtub, lan siji liyane minangka bedside, kanggo cepet nguripake lampu ing kamar supaya monsters mlayu.
Kasus kasebut dicithak kanthi tradisional ing printer SLA, piranti kasebut miniatur, kasus kasebut cilik, panggunaan teknologi cetak iki dibenerake.
Ndeleng model sing dicithak
Magnet dipasang ing kasus lan tutup kompartemen baterei.
