• Proiectul este reprezentat de o masinuta care poate fi controlata dintr-o aplicatie Arduino. Acest lucru este posibil printr-un modul bluetooth HC-05 conectat la placuta arduino uno. Aceasta se afla pe un sasiu de robot.
• Masinuta poate avea mai multe scopuri:
  1. Poate fi folosita pe post de vehicul transport/poate cara anumite chestii: Ex: Iti poti aduce o ciocolata din bucatarie in sufragerie doar cu ajutorul telefonului
  2. Poti pune un servetel sub ea, aceasta curatand zonele prin care se va plimba
  3. De asemenea, aceasta poate fi folosita si pe post de simpla jucarie.

Lista componente

1. Arduino Uno
2. Placa de control motoare L298n
3. 4 motoare
4. Baterie
5. Modul Bluetooth HC-05
6. Sasiu robot
7. Cabluri
