RGB LED light strip

RGB light strip is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components.

It internal include intelligent digital port data latch and signal reshaping amplif ication drive circuit.

Micro:bit Breadboard Adapter

This Microbit expansion board allows you to connect the Microbit expansion IOs to the breadboard,

which makes it very easy to create various creations.

Rain Module

When there is no water droplet on the sensor board, the DO output is high level, the switch indicator light is off.

Comparator output with clean signal, good waveform and more than 15mA strong driving ability. Output form: digital switching output (0 and 1) and analog AO voltage output.

LCD1602 display

LCD1602, or 1602 character-type liquid crystal display, is a kind of dot matrix module to show letters, numbers, and characters and so on. It's composed of 5x7 or 5x11 dot matrix positions; each position can display one character. There's a dot pitch between two characters and a space between lines, thus separating characters and lines. The model 1602 means it displays 2 lines of 16 characters.

4-digital display

This is a basic, 4-digit 7-segment display . It has a common anode. The display features one decimal point per digit, and individually controllable apostrophe and colon points. The LEDs have a forward voltage of 3.4VDC and a max forward current of 20mA.

Ultrasonic sensor

An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal. Ultrasonic waves travel faster than the speed of audible sound (i.e. the sound that humans can hear). Ultrasonic sensors have two main components: the transmitter (which emits the sound using piezoelectric crystals) and the receiver (which encounters the sound after it has travelled to and from the target).

OLED 0.96 inch display

OLED 0.96 inch is a monochrome graphic display module with a built-in 0.96 inch, 128X64 high-resolution display. OLED 0.96inch is able to work despite the absence of backlight. In a dark environment, contrast of OLED display is higher than LCD display. This device is I2C or SPI compatible.

Servo

A servo (servomechanism) is an electromagnetic device that converts electricity into precise controlled motion by use of negative feedback mechanisms. Servos can be used to generate linear or circular motion, depending on their type.

Potentiometer

The potentiometer is an instrument used for measuring the unknown voltage by comparing it with the known voltage. It can be used to determine the emf and internal resistance of the given cell and also used to compare the emf of different cells.
