Hi, i am very new to projects with a raspberry Pi and have decided that i would like to turn one into a remote control car, i have been looking and possible waves i could use for the wireless transmission and i only seem to be able to find WiFi, bluetooth, or infared, and none of these really have the range i was looking for, i would like it to have a range of around 50 metres minimum, im not really sure if this is even close to possible but there is no harm in asking i guess. I am also uneducated in regards to how i should power this thing. i have established that the two motors will demand around 5ish volts, how do i go about solving this issue because i believe that the raspberry pi (very old i know, thats why im turning it into a car

) can only send 3.3 volts how do i go about changing this, it will obviously need to be powered without being plugged into a wall and am unsure how to setup a battery pack and raspberry pi without blowing it up. Thanks in advance
P.S sorry for my noobiness
