Assignment¶
For this weeks assignment I chose to connect a PIR motion sensor to my board. I chose a motion sensor because I plant to make my final project motion sensing. The first thing that I did was look up the device I was using called an HC-SR501 motion sensor. When I looked it up I found this website https://lastminuteengineers.com/pir-sensor-arduino-tutorial/. It was very helpful in figuring out the layout of the device and how to use it.
The next thing I did was I made it work with an ardiuno, which I was able to do successsfully using the code from the above website.
The next thing I did was try to hook it to my own board along with neo pixels which I tried unsuccessfully to do for two days until I remembered that one of my headers can only be used for programming and I had fried an Attiny. So I tried it with just the motion sensor and got it to read it. Sadly because the board did not have a pullup resistor on it it could not intepret the data the the motion sensor was sending to it so it came up as a backwards ? on the serial monitor.
