Waveshare 4-DOF Metal Robot Arm Kit for micro:bit, Bluetooth version

Waveshare 4-DOF Metal Robot Arm Kit for micro:bit, Bluetooth versionThis starter robotic arm kit includes: servo driver board, metal mechanical arm structure, and 4x metal gear servos. When used with the micro: bit, it is easy to control the arm by smart phone through Bluetooth connection. Servo Driver Features: micro: bit edge connector, directly pluggable I2C controlled, using only 2 pins Up to 16 Channel servo PWM outputs, 12 bit resolution for each channel (4096 scales) Integrates 5V regulator, up to 3A output

This allows students to control their robots remotely and share their creations with others

Energy-saving Life 3

or a high-dropout-voltage LED from this board

many modern computers won't work well

which makes it a great choice compared to classic Bluetooth which had (and still has) a lot of restrictions around it on the iOS platform

Compared to conventional gas sensors

Adafruit 16x2 Character LCD + Keypad for Raspberry Pi

These are best used by electronics geeks who have experience and are comfortable working with delicate electronic components

The electrical conductivity sensor (EC sensor) measures the electrical conductivity in a solution which usually used for aquaculture and water quality testing
