The Cobra Line Follower Array provides 4 X QRE1113 IR reflectance sensor mounted on a 9mm pitch Each sensor is comprised of two parts - an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate.
The Studica Servo Power Module is a 6V, 60W power injector that enables the use of high-power RC servos. The Servo Power Module passes through input signals unaltered while providing up to 60W of total output power across all eight channels. The input and output channels accept standard 3-wire, 0.1” pitch, servo/PWM cables.
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.
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.
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)
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.
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.
