i brought my relay switch and MB102 power supply IC to test my HC-SR501 pyroelectric motion sensor. the MB102 provided 5V power to both the relay switch and motion sensor. i first tested the relay, which i could trigger to open or close by connecting the input wire to the 5v column on the breadboard. the relay switch would open with a small clicking sound and light up the onboard led. then it came time to test the motion sensor. the output from the sensor went into the input of the relay. once powered, every time the sensor detected motion, the relay would click and light up. of course i didn't have anything attached to the relay, but i could've added a string of 12V led strip lights that would light up whenever somebody was around. there's a lot of possibilities, the relay could be triggered with any kind of sensor: motion, sound, temperature. i could also wire in an arduino or raspberry pi and trigger the relay based on more complex conditions.
of course there was the 1pm patriots-bills game in buffalo. patriots won but won ugly. offense was ineffective, brady finished the game without a touchdown pass. gostkowski once again missed an extra point kick. new england was up 13-0 after the first quarter, but couldn't score anymore in the first half. buffalo got within 3 points in the 3rd quarter, but pats scored 3 points to put the score 16-10. in the 4th quarter neither team scored. new england won because of the defense, and likewise the bills had a chance to maybe win thanks to their defense as well.
