Testing the Radio

For our Primary Mission we used one radio to send data from the CanSat, and another one to receive data at the laptop. We used the USB converter to connect one radio to the laptop. 

We connected the radio (that sends the data to the computer) pin to the Arduino TX pin.

Testing the Radio

We decided to test the radio. We set up the circuit by connecting the arduino, the breadboard to one of the radios and we plugged in the other radio into our computer. 

Wei Ying and Georgina stood in one spot holding the computer with the radio connected to it, while Aoife and Terri-Ann held the other radio and . We wanted to find the distance between the radios until the connection was lost. 

We did three tests in total.

• Test 1: 0.38km before disconnection 
• Test 2: 0.42km before disconnection
• Test 3: 0.39km before disconnection
