Yahoom Micro:bit camera

The Yahoo Micro:bit Camera is an innovative educational tool designed to integrate camera functionality with the BBC micro:bit microcontroller board. This setup allows students and enthusiasts to explore concepts of computer vision, IoT, and creative programming in an accessible and engaging way.

Hardware Requirements

BBC Micro:bit Board:

A microcontroller with built-in Bluetooth and GPIO pins.

Camera Module:

It includes ESP32-CAM.

Servo Motor:

Rotates the camera to allow capturing images or video (e.g., left, right, and forward).

Driver Expansion Board:

Interfaces the Micro:bit with servo motor.

Smartphone:

Acts as the display and control device.

Jumper Wires

Jumper wires will be used to make connections between the components.

Power Supply:

Battery pack or USB connection for the Micro:bit.

To perform the assembly, we connect:

For WIFI camera :

the VCC pin has an energy of 5V

the GND pin to the GND pin of the Micro:bit card

the TX pin to the P0 pin of the Micro:bit card

the RX pin to the P1 pin of the Micro: bit card

For the first servomotor :

the pin S to pin S1 of the DF-Driver board

the pin (+) to the VIN pin of the DF-Driver board

the pin (-) to the GND pin of the Micro: bit card

For the second servomotor :

pin S to pin S2 of the DF-Driver board

the pin (+) to the VIN pin of the DF-Driver board

the pin (-) to the GND pin of the Micro: bit card

Programming Micro:bit using Makecode

Here is the program which allows to control the rotation of the camera platform by the Micro:bit card.

Mobile application :

Here is the mobile application which allows the smartphone to connect to the camera by wifi and control the rotation of the camera platform.
