+ | With these workshops, which usually take around 5 to 6 hours, we hope to give the students an inside into our work, ranging from (digital) manufacturing at our FabLabs to the electronics design and at the end to microcontroller programming. The responses we had with these workshops were positive and engaging. | ||

+ | In this part, we are working on the integration of the Camera in a PCB and mounted inside the Bird Box. | ||
+ | |||
+ | What does the PCB consist of? Before answering this question, I would like to give you a look at how the PCB was developed. | ||
+ | |||
+ | First, we identified the goal. We want an electronic device that takes pictures in the dark (as inside the box during night it's almost complete darkness) and then uploads these photos to an online server to be analyzed. | ||
+ | |||
+ | Then we need a Camera, and in our case, the **ESP32-S3 XIAO Sense** was a good option as it's very small, has low power consumption, | ||
+ | |||
+ | ^ Part ^ Number | ||
+ | | ESP32-S3 XIAO Sense | 1 | 13 | ||
+ | | IR333-A IR LED | 4 | 0.49 | ||
+ | | BD139 NPN Transistor | ||
+ | | Jumpers MM | 25 | 6 | | | ||

+ | | DC Battery 3.7V 2200 mAh | 1 | 19 | ||
+ | | Resistors | ||
+ | | Solar Cell | 1 | ||
+ | |||
+ | *So let's first speak about some parts separately.* | ||
+ | |||
+ | - **ESP32-S3 XIAO**: | ||
+ | |||
+ | This board is being offered by Seeed Studio. The Seeed Studio XIAO Series are diminutive development boards, sharing a similar hardware structure, where the size is literally thumb-sized. The code name " | ||

+ | |As you can see, it comes in two parts which can be attached together, one part has the SoC and the other part has the Camera, Microphone, and the SD-Card slot.| | ||
