What does “P” mean? “P” is for “panel mount” in this product. This Grove – Button is a sister version of original Grove - Button. They are identical except the Grove connecter is moved to the back so that you can easily use it as a neat and wire-free human interface device.
This is a simple yet enjoyable twig to use. The piezo can be connected to digital outputs, and will emit a tone when the output is high. Alternatively it can be connected to an analog pulse-width modulation output to generate various tones and effects.
Sensor is to create Digital (Lo Pulse) output to Particulate Matters (PM). Lo Pulse Occupancy time (LPO time) is in proportion to PM concentration. The output is for PM whose size is around 1 micro meter or larger. We can use the sensor to detect the dust in clean room.
EMG detector is a bridge connects human body and electrical, the sensor gathers small muscle signal then process with 2th amplify and filter, the output signal can be recognized by Arduino. You can add this signal into your control system. Note: The sensor cannot be used for medical purposes. In standby mode, the output voltage is 1.5V. When detect muscle active, the output signal rise up, the maximum voltage is 3.3V. You can use this sensor in 3.3V or 5V system.
The Hall Sensor measures the Hall Effect, which is a production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor as well as a magnetic field perpendicular to the current. The output of the continuous-time switch Hall sensor on this Twig switches low and turns on when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high and turn on when the magnetic field disappears.
This module is based on the color sensor TCS3414CS with digital output I2C. Based on the 8*2 array of filtered photodiodes and 16-bits analog-to-digital converters, you can gain the color chromaticity of ambient light or the color of objects. Of the 16 photodiodes, 4 have red filters, 4 have green filters, 4 have blue filters and 4 have no filter(clear). With the synchronization input pin, external pulsed light source can provides precise synchronous conversion control.
Key Features:
Grove compatible interface
16-Bit digital output with I 2C at 400 kHz
SYNC Input Synchronizes Integration Cycle to Modulated Light Sources
Operating temperature range -40°C to 85°C
Programmable interrupt function with User-Defined Upper and lower threshold settings
I2C Hub Grove is an extension Grove module for connecting multiply I2C devices to Grove Base Shield. It can use with Universal 4 Pin to X2 4 Pin cable and connects up to 7 I2C divices which may cover most developing purpose.
This IR Distance Interrupter features a high-sensitivity RFR-359F photoreflector to perform distance detection function. The photoreflector consists of a GaAs infared light emitting diode and a silicon planar phototransistor. When the infrared light emitted by the emitter gets reflected on a surface that blocked it, the phototransistor can pick up the signal for distance calculation. This module is panel mounted so that you can easily implement it on the surface of robots or other projects without wiring clutter. Also a potentiometer for adjustment and an indicator LED are arranged on the back for easy and clear use.
Done with tedious mono color backlight? This Grove enables you to set the color to whatever you like via the simple and concise Grove interface. It takes I2C as communication method with your microcontroller. So number of pins required for data exchange and backlight control shrinks from ~10 to 2, relieving IOs for other challenging tasks. Besides, Grove - LCD RGB Backlight supports user-defined characters. Want to get a love heart or some other foreign characters? Just take advantage of this feature and design it!
Grove - Mini Fan is a DC motor driver base on AVR microcontroller Atmega168,you can change code by breakout , this module also reserve servo connector,it can driver servo by change code ,Grove - Mini Fan is design for kids, which is use soft fan-leafed in order to avoid unnecessary damage.
Grove - OLED 0.96'' is a 16 color grayscale 96×96 dot matrix OLED display module with Grove compatible 4pin I2C interface.Grove - OLED 0.96" is constructed with 96 x 96 dot matrix OLED module ([ LY120])and SSD1327 driver IC. The characteristics of this display module are high brightness, self-emission, high contrast ratio, slim / thin outline, wide viewing angle, wide temperature range, and low power consumption.
Grove - OLED Display 1.12" is an OLED monochrome 128×64dot matrix display module with Grove 4pin I2C Interface .The characteristics of this display module are high brightness, self-emission, high contrast ratio, slim outline, wide viewing angle, wide temperature range, and low power consumption. It has bigger screen and uses all the columns from the SSD1308 chip so that it can display more contents than the OLED 96×16.
This is a simple to use PIR motion sensor with Grove compatible interface. Simply connect it to Stem shield and program it, when anyone moves in its detecting range, the sensor outputs HIGH on its SIG pin. The detecting range and response speed can be adjusted by 2 potentiometers soldered on its circuit board, The response speed is from 0.3s - 25s, and max 6 meters of detecting range.
The RTC module is a member of Twig. It is based on the clock chip DS1307 which supports the I2C protocol. It uses a Lithium cell battery (CR1225). The clock/calendar provides seconds, minutes, hours, day, date,month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator.
Grove - Servo is a bonus product for Grove lovers. We regulated the three-wire servo into a Grove standard connecter. You can plug and play it as a typical Grove module now, without jumper wires clutter. For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
What does “P” mean? “P” is for “panel mount” in this product. This Grove – Switch is a mini SPDT slide, great for “ON/OFF” situations. It’s such a reliable switch of great build quality that we adopt it on many of our boards. You should stock some for your Grove prototyping system.
