Curious if anyone has had success using arduino components utilizing the 3 wire plugs? We were able to use some IR sensors and get the brain to respond with a reading.
Trying to utilize SR04 ultrasonics and haven’t had luck. I have some old Vex3 ultrasonics that read fine but as I try to imitate the wiring for the SR04’s , it’s reading 1.00 and doesn’t change.
Thanks!
