I did bring my own Arduino with me this week but I left the USB-B cable needed to power it at home so I had to join a group.
We made a few different circuits, with 0-2 switches, in both series and parallel. This week was good revision for me in explaining how breadboards work and the differences between how series and parallel circuits distribute electricity. Parallel circuits are generally more effective as they distribute evenly between the components, unlike series where you may, for an example from real life I did one time, attach a 12 volt battery to twelve 1 volt LEDs and blow up the first one and give your friend a nosebleed because you used 12 times the amount of voltage you were meant to.]]> 2022-03-28 02:25:37 UTC https://padlet.com/rachaelhoffman1/zt2tthgr6sad3kp1/wish/2116205743 rachaelhoffman1 https://padlet.com/rachaelhoffman1/zt2tthgr6sad3kp1/wish/2116240493 Electric paint seems so cool. Would love if it worked sometime. Okay with that out of the way: this was a frustrating lesson. I loved the concept though. Each individual component of mine worked - including the electric paint which I shared with the person next to me. For a while I suspected that my problem was trying to include the photoresistor which the guide recommended but no one else was using because no one else had one. However, when I took it out and tried to make just a simple circuit on a separate piece of paper with the conductive paint, an LED, and the Arduino as the powersource it still didn't work. This is something I will have to play around with more at home to see if I can get the conductive paint to work for me by using varying quantities. Maybe it's a "less is more" kind of situation but I don't know.]]> 2022-03-28 02:49:11 UTC https://padlet.com/rachaelhoffman1/zt2tthgr6sad3kp1/wish/2116240493 rachaelhoffman1 https://padlet.com/rachaelhoffman1/zt2tthgr6sad3kp1/wish/2116267810 A refreshing change of pace from last week. Constructing a circuit from materials I'm familiar with (although I hadn't actually used a temperature sensor before) was pretty simple. I set it up with red, orange and green lights so there were two ways to tell how warm it was: how many lights were on, or which colour lights were on. Reflecting on this, I would've picked different colours or reversed these colours so it was more like a heat map, with red as the hottest.
The code on this was interesting. Some of it was familiar to me, such as setting values of "LOW" and "HIGH" for off and on for the LED lights, but the values for the temperature sensor was new to me. I vaguely remember having used the serial monitor before, probably for reading photoresistor outputs but it has been so long that it was essentially new learning for me. ]]> 2022-03-28 03:09:50 UTC https://padlet.com/rachaelhoffman1/zt2tthgr6sad3kp1/wish/2116267810
