The Sharp IR Distance Sensor GP2Y0A21YK0F uses a beam of infrared light to reflect off an object to measure its distance. Because it uses triangulation of the beam of light to calculate the distance, it is able to provide consistent and reliable readings which are less sensitive to temperature variation or the object’s reflectivity. The sensor outputs an analog voltage corresponding to the distance of the object, and can easily be read using an inexpensive analog to digital converter (ADC) chip.

• Step File

• Stable, accurate distance measurement
• High precision, blind spots (3cm) super close
• A full set of ranging process

The Danger Shield is an add-on for the [Arduino] micro controller board. It contains a variety of fun and useful electronic circuits that you can use to do fun and useful things. It is a fully self-contained shield. You plug it into your Arduino, and you can immediately start using it. No extra things to hook up, no external components. Just a really rad board ready to rock.

3-Axis Compass module, a member of grove family uses I²C based Honeywell HMC5883L digital compass. This ASIC is equipped with high resolution HMC118X magneto-resistive sensors and a 12-bit ADC. It provides compass heading accuracy up to 1° to 2°. Signal conditioning like amplification, automatic degaussing strap drivers and offset cancellation are inbuilt. This grove module also includes a MIC5205-3.3 for power supply requirement. Hence user can connect any 3.3V to 6V DC power supply.

Grove - BLE (dual model) v1.0 uses CSR dual mode Bluetooth chip,with the ARM architecture single chip which supports AT instructions, Users can develop flexibly according to the serial baud rate, equipment name, pairing password.

A general purpose LED module in Grove form factor, available in different colors. The ingenious PCB design enables you to bend the LED to any position you want, which makes it easy to use it standalone, horizontal or Panel Mount(from left to right in below pics)

Key Specification:

• Standard Grove connector
• Operate voltage: 3.3v/5v
• Emitting Color: Blue

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.

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.

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.

 

Key Features:

• Grove Compatible
• 3.5mm Connector
• 6 Disposable Surface Electrodes
• Power supply voltage: 3.3V-5V
• 1000mm Cable Leads
• No additional power supply

Grove - I2C ADC is a 12-bit precision ADC module based on ADC121C021. It helps you increase the accuracy of value collected from analog sensor by providing a constant reference voltage. Because its address is changeable, you can use up to 9 I2C ADC at the same time at most. At the other hand, this module provides auto sleep function which lowers the power consumption considerably.

Key Features:

• Low power consumption
• High precision
• Automatic power-down mode
• Address changeable

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!
