Starter bundle harness is a board holding the goods of grove-starter bundle ，include the LCD and battery box，arduino，seeedunio and ect.
Based on the excellent ADXL-345, this digital 3-axis accelerometer has excellent EMI protection. Its variable output makes it suitable for a wide range of applications
This temperature & humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and the temperature is measured by a negative temperature coefficient (NTC) thermistor. It has excellent reliability and long term stability. Please note that this sensor will not work for temperatures below 0 degree.
The Light sensor module uses the GL5528 photoresistor to detect the light intensity of the environment. The resistance of the sensor decreases when the light intensity of the environment increases. The chip LM358 is used as a voltage follower to enable you get a accurate data.
his slide potentiometer is a linear variable resistor with a total resistance of 10k. When you move the lever from one side to the other, its output voltage will range between 0 V to the VCC you apply.
This new version of LED twig consists of one green LED. It operates from 5V DC. Perfect for use on Seeeduino digital outputs, or also can be controlled using pulse-width modulation. Each LED has a current-limiting resistor, which protects the LED and the Arduino from high current.
Grove - Screw Terminal with four 3.5mm pitch pins rate up to 125V @ 6A. Terminal can accept 30 to 20AWG wire. It is most common pitch screw terminal. This grove has four ports, include GND, VCC and two other undefined ports.
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.
This new version of button twig contains one independent button, which are configured with pull-down resistor ? Ready for use with our microcontrollers as digital input. The button signals the SIG wire,NC is not used on this twig.
The tilt-switch twig is the equivalent of a button, and is used as a digital input. When the switch is level it is open, and when tilted, the switch closes. It is wired to the SIG line, NC is not used on this twig. There's a surface-mount resistor .
Grove - Thumb Joystick is a Grove compatible module which is very similar to the 'analog' joystick on PS2 (PlayStation 2) controllers. Two direction movements will output different analog signals as they are actually two potentiometers. The resistor is ~10k for each.
It is consist one coin type motor which is a Permanent Magnet coreless DC motor. It vibrates when the input is logic HIGH. It is very easy to drive and Grove compatible. Can be used in toys and cell phone modules.
The Universal 4 Pin Buckled Cable is made for the Grove System to connect all of the Twigs to the Stem - Basic Shield or to other Twig compatible boards for quick prototyping.
This module is an incremental rotary encoder. It encodes the rotation signal from the axis and output the signal by electronic pulse. The Grove – Encoder is one of the Grove series and has a standard Grove interface. When you need to add a rotary knob to your project, for example a volume knob for a speaker, a selection panel or a digital input, this...
Some customer complain that can not use Arduino to control Grove modules directly. So we make this Grove to 4 Pin 2.54 female jumper wire. With this wire, you can easily connect all of Seeed Grove modules to any 2.54mm pitch connectors. 5 PCs is included in one pack.Length of each wire is 20cm. Note: Grove side uses buckled connector.
The Sound sensor module is a simple microphone. Based on the power amplifier LM386 and the electret microphone, it can be used to detect the sound strength of the environment. The value of output can be adjusted by the potentiometer.
