Week 14

We bought a new lcd with a build in receiver for our camera. the transmitter was able to successfully feed the video to the LCD screen! however, the downside to it would be there's no way to save those images to our memory. thus reviewing the footage would not be possible. at least with a computer we can use a screen recording software to record the video but now it wouldnt be possible. '

Continuing on with our wall avoidance code, we realised that changing the pixhawk straight using the arduino will not work as the transmitting distance between the two is too close. Doing this will immediately crash the drone. We have been told to go through a medium instead. Therefore, we decided to have the arduino go into the receiver and from the receiver to a ppm encoder and finally to the pixhawk itself. For the first iteration, we decided to try it with the IR sensor. The IR sensor proved to have been working. It is able to control the motors and move it back when it sensed an obstacle. However, if the distance the IR sensor senses is not between 20cm and 1.5m, the IR sensor will output random numbers. For example, if the IR sensor senses 1.6m, it can output out 40cm, 1m, 50cm etc. This will affect the way the code works making it impractical to use the IR sensor.
