In general, pot citi starea unui buton si stiu ca a fost apasat sau nu, dar pentru anumite aplicatii e bine ca sa nu se schimbe ceva daca am apasat din greseala butonul, ci doar daca apas un timp destul de lung, de exemplu 3 secunde.
Am realizat repede un montaj care are un buton fara retinere (pe breadboard sunt 2 butoane, dar ma folosesc doar de unul) si 2 leduri, fiecare inseriate cu cate o rezistenta de 220ohmi fiecare, pentru limitare curent prin ele si prin pinii microcontrolerului de pe placa.
Un led galben indica faptul ca butonul este apasat (aprindere stroboscopica, doar pentru efect placut), iar ledul rosu se aprinde doar daca butnul a fost apasat suficient de mult (3 secunde).
Schema este foarte simpla:
Din program (pushtime1button.ino) pinul alocat butonului este in starea HIGH, deoarece am activat rezistenta interna de pull-up (de cca 10kOhmi).
Pentru a fi mai usor de inteles ce am scris mai sus, va recomand vizionarea unuia din cele 2 filmulete:
La solicitarea lui Mircea Craciun, am realizat un termostat, care mai are posibilitatea de a controla si umiditatea dintr-o incinta (higrostat). Senzorul pentru umiditate si temperatura este unul dedicat, AM2302 (cunoscut si ca DHT22 cand e montat pe un cablaj si are o rezistenta de 4k7 intre +5V si pinul de date).
Precizia acestui senzor este destul de buna, la temperatura de +0,5 grade Celsius in domensiul de -40..+80 grade Celsius si pentru umidtatea relativa +2%RH in domensiul de 0..100%. Schema de conectare este:
Dupa cum se observa, am reprezentat cele doua variante de senzor, montandu-se doar una din ele..
Am pus 2 led-uri pentru a avea o incatie, dar daca se inlocuiesc cu relee, ele pot comanda o centrala si un servomotor (sau electrovana) de eliminare umiditate, dupa cum sunt date comenzile din sketch-ul LCD1602_thermostat_humidity_ver1m0.ino.
Din celel 3 butoane fara retinere se regleaza temperatura dorita, intervalul acceptat de scadere a temperaturii odata depasite (histerezis), umiditatea si intervalul acceptat de scadere al umiditatii odata depasite.
- reglaj temperatura:
- reglaj interval acceptat de scadere a temperaturii odata depasita (histerezis)
- reglaj umiditate:
- reglaj interval acceptat de scadere a umiditatii odata depasite (histerezis)
In graficul de mai jos se cele 3 cazuri: temperatura scazuta (BELOW), temperatura optima (OK) si temperatura prea mare (OVER):
In timpul functionarii,pot fi mai multe stari (am simulat cateva):
- temperatura si umiditate in parametrii doriti (optim):
- temperatura scazuta si umiditate mai mica decat pragul admis:
- temperatura in parametrii, umiditate mai mica decat pragul admis (bun):
- temperatura in parametrii, umiditate prea mare:
- temperatura scazuta si umiditate prea mare:
- temperatura prea mare, umiditate crescuta:
Am facut si 2 filmulete, care prezinta mai bine modul de reglaj al parametrilor:
Pentru diverse sisteme de automatizare in care se doreste reglajul anumitor parametrii se folosesc meniuri mai simple sau mai complexe.
In articolul Tutorial: manage menu and LCD display with Arduino este prezentat un meniu controlat cu 4 butoane fara retinere (selectie, renuntare, inainte/dreapta inapoi/stanga) in care se foloseste o libraria libraria MenuBackend modificata. In acel material se folosesc 4 butoane fara retinere cu contact intre pinii de intrare si plus, iar pinii sunt conectati prin rezistente la masa.
iar meniul are 3 submeniuri, primul submeniu mai are 2 sub-submeniuri, al doilea submeniu are 3 sus-submeniuri, iar al treilea submeniu e fara sub-submeniuri.
Eu am modificat sketch-ul pentru a elimina rezistentele, folosindu-ma de cele interne, pe care le pun in 1 logic (HIGH), deci am contact catre masa, schema devenind:
si diverse faze se pot vedea in imaginile urmatoare:
- meniul principal
- primul submeniu
- al doilea submeniu
- al treilea submeniu
- sub-submeniurile de la submeniul 1:
- sub-submeniurile de la submeniul 2:
Dupa cum am vazut cum functioneaza, am rescris sketch-ul (3menu_3submenu_each_ver2m0.ino) sa am cate 3 sub-submeniuri la fiecare submeniu, iar asta se vede in filmuletele:
Fata de articolele anterioare, unde aveam reglaj complet la ceasul RTC cu DS1307 dintr-un encoder (folosindu-ma de informatiile de la http://andydoz.blogspot.com/) acum am 3 taste... Schema de conectare este similara, deoarece am pastrat conexiunile principale, punand chiat si tastele ca la encoder):
In modul obisnuit, pe ecranul apar ciclic informatii despre:
- ora:
- data:
- temperatura si umiditate:
Daca apas scurt pe tasta MENU/NEXT apare pe ecran ID-ul meu "niq_ro":
Daca apas lung (mai mult de 3 secunde) se intra in modul de reglaj:
