Reed Switch Module for Arduino Projects & Raspberry Pi

so hello and welcome back if you've been following this series this is a video on model train automations is video number four in the series and this is going to look at controlling the Train automatically using a sensor to detect the train and slowing and restarting the locomotive as appropriate if you've missed the previous videos then they're all linked in the description feel free to go back to them first first one is on power supply converting AC to DC the second one is on the H bridge used not to change the polarity of the DC supply to change the direction of the Train part three looks at PWM which is used to control the speed of a DC motor and this video is on detecting and automating the train this will work with raspberry pi or an Arduino whichever you prefer we're going to detect the train using a reed switch now a reed switch it's a little case with two switch contacts inside
