Arduino Bluetooth car controls by phone

Salut, Doresc să fac o machetă în care să fie reprezentată o intersecție semaforizată. Vreau să folosesc un modul Bluetooth conectat la Arduino, să-mi detecteze dispozitivele Bluetooth active (BLE Scanner), iar apoi, în funcție de câte dispozitive setez din cod (o limită), să se schimbe timpii de semaforizare. Totodată, mai vreau să conectez un LCD, care să-mi afișeze timpii prestabiliți de semaforizare, iar apoi timpii în urma detectării a X "autovehicule" (dispozitive BT).

Salut, Am vazut profilul vostru si cred ca v-ati potrivi pentru proiectul meu. Am nevoie de un dispozitiv care sa permita trimiterea de imagini (jpg si gif) pe un display epaper prin bluetooth. Display-ul este acesta (de la un kindle 3) El mai are nevoie de un controller inainte de a fi conectat la un microcontroller (cred ca un Arduino Due ar fi ideal). Alimentarea va trebui sa fie pe baza unei baterii. Cablul dintre display si controller va trebui sa fie putin prelungit (sa aibe undeva la 40cm ) Sa-mi spuneti daca v-ar intresa acest proiect. O zi placuta, Cristi
