1. Lab 3 - Video Streaming Web Server and Robot Car
2. Introduction The purpose of this
tutorial was to stream a live video feed to the web server, get data
from a sensor to output to the web server, and control a robot car
using the ESP-32 Cam via the web server.
3. Results
Task 1: This
task asked us to have the ESP-32 Cam stream a live video feed to the
web server. The code for this task is in the Tutorial3 -> task1
folder.

Task 2: This
task asked us to have the ESP-32 Cam stream a live video feed to the
web server while outputting results from reading a BMP180 sensor. The code for this task is in the Tutorial3 -> task2 folder.

Task 3: This
task asked us to have the ESP-32 Cam wired on a proto-board to control
a robot car. Figure 3 shows the wired car, the video showing the car
working is shown in Task 4. The code for this task is in the Tutorial3 -> task3 folder.

Task 4: This
task asked us to have the ESP-32 Cam controlled robot car
accelrate slowly as the buttons were pushed, and rotating the video
feed so it was the right side up on the monitor. Figure 4 shows the car
driving with an acceleration function built in and the video feed
flipped to teh correct orientation. The code for this task is in the Tutorial3 -> task3 folder.

5. Discussion This
was a good lesson in the ESP32-CAM's advanced functionality.
Controlling the robot car via a web server was awesome and coming up
with an acceleration function for DC motors without PWM pins was a good
challenge. This was also a good chance to refresh our soldering skills
so we didn't end up burning out a voltage controller or the ESP-32 Cam
itself.
