1 00:00:01,000 --> 00:00:11,589 Welcome to CANSAT EVA! 2 00:00:11,589 --> 00:00:18,820 Let's talk about the primary mission. 3 00:00:18,820 --> 00:00:25,820 The CANSAT competition has two main challenges, the primary mission and the secondary mission. 4 00:00:25,820 --> 00:00:34,820 The team must build a CANSAT and program it to accomplish the following compulsory primary mission. 5 00:00:34,820 --> 00:00:50,079 After release and during descent, the consort must measure air pressure and air temperature and transmit the data as telemetry to the ground station at least once every second. 6 00:00:50,079 --> 00:01:05,079 A very popular alternative to the temperature and pressure sensors is BMP280, which is a digital pressure sensor. 7 00:01:05,079 --> 00:01:16,079 It combines a pressure and temperature sensor into one unit, making it an ideal solution for the cancer's primary mission. 8 00:01:16,079 --> 00:01:36,079 Besides, it is cheap and very small. This means you can complete the primary mission while using very little of the available budget and size of your consent, making more exciting secondary missions possible. 9 00:01:36,079 --> 00:01:48,319 Now we're going to see how to use the Arduino IDE to run our program for the primary mission. 10 00:01:48,319 --> 00:02:18,699 piano plays softly
