we got the arduino all together and got the temp sensors to talk to the arduino. we got two temperature sensors off our older brother. They are called DS18b20. It turns out they are not analog - they talk on a "one wire bus". We had to download some arduino code and installed a library called "One WIre". We didn't know how to write the fancy code to read the sensors, but we cut and pasted off someone else's website, and it worked! We tested them two cups of cold and hot water. We switched the sensors and they changed readings! and BONUS we got a SD card that kept track of the temps! we tested it and it worked. it took very long and many problems happend.

So we tried to code an app to make it where we could take photos (and send its location) with an android phone... one problem.... theres LOTS of problems... the app inventor does not take photos... instead it brings you to the camera. so we decided to download an app called LapseIt its a good app because you can set how long you want to wait for a photo to be taken, pics you wanna take, potato, etc. we tried it on my pet bird and our dog. it wasn't that amazing because our dog and bird dont do much... but i guess you could waste about 20 seconds of your life watching these: ![]()

For Christmas our brother got us an Arduino UNO R3 (an Arduino is a circuit board) and what do you suppose we got it for? well... what everyone wants to know... how COLD it is up there (its mostly around -60 degF)
REPEAT -60 (its not 960-) well we got a breadboard and some wires we can connect to the Arduino and some heat sensors. its interesting and is in code of C++. Its good besides the fact we dont even KNOW C++! We did a Blink program where it blinks an LED. You can also set the time of how long it turns on and how long it turns off. We also used a program to read a voltage from a resistor and show it on the laptop. We combined the programs so we were able to use the voltage - the voltage is how many seconds the LED turns on for. |
