Day 9 of Mechatronics
Today I skipped the buzzer lab and went straight into what I remember to be a very important concept in programming (because of prior exposure to programming in C) the if- else statements. I used a TIP 120 transistor which has a different pin set up than the other transistors and after struggling to get the set up to work we (the instructor and I) had given up to make it work then it worked with magic or as my uncle would call it with MFM. Next, I went back to setting up a buzzer to turn on or off when I used a potentiometer at different resistances. Once that was done I set up to buzzer to activate with different ranging sounds for the fun of it and an LED to light up for fun (I didn't know it was a lab). From there I used a photo resistor to activate the buzzer for certain values in my program which came out to be very obnoxious after a lot of trial and error.
