Kit containing everything needed to build a robotic arm in aluminum alloy with 4 degrees of freedom and a gripper to grasp objects, all managed via the micro:bit board (not included)

The robotic arm, once the micro:bit board has been programmed, can also be controlled via Bluetooth connection through a simple smartphone App.

The electronic board has a connector for inserting micro:bit, a driver based on the PCA9685 chip that allows you to simultaneously manage up to 16 RC servos or LEDs, an I²C interface, a 5 volt voltage regulator capable of supplying a current of 3 A. The 16 output ports have a resolution of 12 bits, each with 3 pins: V+, GND and PWM output. Each PWM works completely independently, but they must all have the same PWM frequency.

The package includes: 1 x 13kg•cm analog RC servo (MG996R) with metal gears and accessories, 3 x 2.5kg•cm analog RC mini servo (MG90S) with metal gears and accessories, 1 electronic board, 1 power supply with micro USB output (5 volts 3A), 1 RC servo extension cable (150mm), 2 screwdrivers, aluminum alloy parts for the robotic arm and all the mechanical parts necessary for assembly.

• MICROSOFT PXT (BETA) is a programming environment created by Microsoft (still in beta) that supports both a block-based graphical environment, in the style of Scratch, and the Javascript language.
• PYTHON has been and is still being developed to allow the programming of microcontrollers in a language compatible with Python. The opportunity to use the Python language allows for continuity, in a hypothetical educational path, towards the use of more complex systems such as microcomputers capable of hosting GNU/Linux, such as the Raspberry Pi series.
• MICROSOFT BLOCK EDITOR is a visual editor very similar to Scratch and represents the starting point for those who want to start programming. Like Scratch it is very simple to use but it is not a toy. It allows you to
  deepen structured programming and event management. The method of composing a program consists of choosing the blocks that represent the instructions, dragging them into the editor panel, configuring them in the customizable parts and “fitting” them together correctly.
• MICROSOFT TOUCH DEVELOP was developed to create programs for the micro:bit using tablets or other devices with a touch screen. Of course, it can also be used from normal PCs using a keyboard and mouse.
• JAVASCRIPT is a development environment that allows those who have made progress in programming to develop programs using the textual syntax of Javascript, with a guided editor that supports the “click and drag” method for composing lines and blocks of code.

• 25 red LEDs that can be lit at different intensities to create drawings, animations and games.
• Two buttons that can be managed via program to customize its behavior.
• A reset and restart button.
• An accelerometer that can detect and recognize different types of motion such as shaking, rotations and free fall. Useful for making a motion sensor or animated games.
• An electronic compass that can detect orientation and rotation in degrees with respect to North. An additional use could be as a metal detector (magnetic).
• A USB connector to connect the micro:bit to your PC to load software programs.
• A connector for external power supply.
• A Bluetooth Smart Technology module that allows you to connect the micro:bit to other devices equipped with the same technology such as other micro:bits, PCs, smartphones, Bluetooth kits, tablets and cameras.
• A temperature sensor that can detect the ambient temperature.
• A 24-pin connector, five of which have pads suitable for connection with alligator clips. The connector provides analog and digital I/O, communication bus and other features described in more detail below.
