1) ELF Mainboard:
Weeemake ELF mainboard is designed based on a modular design style whose microchip is replaceable. This high-performance mainboard is designed for education.
Replaceable microchip: Support ATMEGA-328P, ESP32 chip, etc
Same port for the motor driver and sensor pin port, easy to use.
Random wiring, work with WeeeCode and Arduino.
2) RGB Ultrasonic Sensor:
The RGB ultrasonic sensor is an electronic module used to measure the distance with a measurement range of 4 cm to 500 cm. It can be used to help a car avoid obstacles or other projects related to range. The ultrasonic transmitter sends ultrasonic waves in a certain direction and starts counting time. The ultrasonic wave spreads in the air, and when the obstacle is encountered on the way, it returns immediately. The ultrasonic receiver immediately stops timing while receiving the reflection wave. The transmission speed of the sound wave in the air is 340m/s. According to the time (T) recorded by the timer, the distance (S) between the transmitting point and obstacle is calculated, that is, S = 340*T/2.
At the same time, both ultrasonic probes have a built-in RGB LED light.
3) Double-way Line-following Sensor:
The line-following sensor uses the feature of infrared that will get different reflection strengths on different colour surfaces. During the driving process of the robot car, the line-following sensor continued to transmit infrared light to the ground. When infrared light encounters a white surface, a long reflection occurs and the receiver on the sensor will receive that reflected infrared; When infrared light encounters a black surface, the infrared light is absorbed, and the sensor’s receiver cannot receive infrared or receive very few. The position of the black or white line is determined by whether to receive the infrared light returned from the reflection or not.
The double-way line-following sensor has two groups of infrared transmitter and receiver tubes S1, and S2.
4) LED Matrix Panel:
The LED panel matrix screen is composed of a blue LED light into a matrix, which can control display numbers, letters or symbols. The LED distribution is 5 rows multiple 7 columns. The sensor comes with a half-transparent black cover.
5) Light Sensor:
The light sensor is a sensor based on the principle of optoelectronic effects of semiconductors (converting optical signals into electrical signals). It can detect the light intensity of the environment around the sensor, convert the strength of light into an electrical signal, and transmit it to the mainboard.
6) Sound Sensor:
Sound Sensor converts the voice signal to an electrical signal based on a microphone. It can be used to detect the sound intensity in the surrounding environment. The detected volume is enlarged by a computing amplifier and then transmitted to the mainboard. It can be used to do interactive projects, such as voice control switches, volume control robot cars, etc.
7) IR Receiver:
The IR receiver has a component that can detect about 38kh IR signals, which can receive infrared signals emitted by the IR remote control. IR remote control is currently the most widely used communication and remote control method, with the advantages of small size, low power consumption, strong signal, etc.
8) IR Remote Controller:
IR remote controller is a commonly used remote control device. It has an IR transmitting light. When pressing the buttons on the remote control, a specific IR light signal will be emitted. This signal is received by the IR receiver and interpreted the signal.
9) Bluetooth 4.1 Module:
This Bluetooth module is designed for remote control. It can connect to the mobile phone Bluetooth, computer Bluetooth, Bluetooth dongle, etc. Not only can it be remotely controlled robots, but also wireless programming, download programs, etc.
