  • Could you post some more information on how you got the safety sensors to work with arduino? Code or rough schematic? I read that when the beam is broken, the voltage goes high, but when the beam is made it pulses for .5ms every 6.5ms. I watched the other video and it didn’t look like you had any additional IC’s, just the arduino? Thanks for any help / hints!

    Thank you for being a great teacher!!!
