| May 22, 2018 at 15:02 | comment | added | abidinberkay | i mean, i worry about the current which is going to raspberry back. i will bind 4 ldr-4 capacitor in parallel and check the current on blue-green-yellow-pink cables in pictures but i am not sure about should i use extra resistor to protect raspberry? image.ibb.co/b4eYko/diren_devre.png | |

Also, the raspberry pi won't explode, but electrolytic capacitors can explode(by explode I mean they might start crackling and smoking) if you wire them backwards. I very much doubt that a 1mf capacitor is electrolytic, though, so you probably don't have to worry. @abidinberkay | |
| May 21, 2018 at 17:55 | comment | added | abidinberkay | thanks man. yes i will look at capacitor +/- signs on it while i am connecting them, thanks again. can you suggest which size of capacitor should i use if i use 3-4 sensors for car to rotate?(for example 1mf capacitor is good for each ldr to prevent raspberry to explode or should i use different size or ohm?) btw i picked your answer as correct, it solved my original question, thanks again. | |

| May 21, 2018 at 15:55 | comment | added | Benjamin Ashbaugh | Exactly. Yes, the rpi will understand from the yellow and green lines - it's no different, really, than your previous circuit, but it's easier to implement. however, PLEASE NOTE: make sure the white bands on the capacitors are connected to negative(the black wires), not the other way around., or else your capacitors might explode! @abidinberkay | |
| May 20, 2018 at 23:48 | comment | added | abidinberkay | can i use that 2 sensors like image.ibb.co/iuGJWT/paralel_pins.png ?? If i bind these ldr-capacitors parallel, can my raspbery understand from the current of yellow and green line ?? | |
