For this practice, I'm going to use the PI's three branches, that is responsible for adapting all the pins GPIO of Raspberry PI of 3.3V to 5V bi-directionally and will allow us to working with the second reserved for the PiCam I2C bus; I will also use plate relays optoacoplados I used in the previous article about home automation.
Kwa tabia hii, mimi naenda kutumia ya Matawi matatu ya PI, kwamba ni wajibu kwa ajili ya kurekebisha vigingi wote GPIO ya Raspberry PI ya 3.3V kwa 5V Bi directionally na kuruhusu sisi kufanya kazi na pili zimehifadhiwa kwa ajili ya mabasi ya PiCam I2C; Pia kutumia sahani zile za kubadilishana optoacoplados nilikuwa katika makala iliyopita kuhusu uendeshaji-oto maskani.
