Hi. I need to this raspberry pi. So its pins are 0 - 3.3v. Which resistor value do i need. I ask if i need to change 47 ohm. Then i ll connect pins where the led is and then read value. Right? Thanx
Hi. I need to use this with raspberry pi. Raspi pins operate in 0 - 3.3v. so which resistor value do i need. I ask if i have to change 47 ohm R. Then i willl connect raspi pins to where the led is and then read value with wiringpi functions. Right? Thanx
