A potentiometer is basically a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name.Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load.
Ebot potentiometer consist of 3 pind namely S,V and G(signal, VCC and Ground respectively.)
Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically. They are very useful devices and allow one circuit to switch another one while they are completely separate. They are often used to interface an electronic circuit (working at a low voltage) to an electrical circuit which works at very high voltage. For example, a relay can make a 5V DC battery circuit to switch a 230V AC mains circuit. Thus a small sensor circuit can drive, say, a fan or an electric bulb.
A relay switch can be divided into two parts: input and output. The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it. This voltage is called the operating voltage. The output section consists of contactors which connect or disconnect mechanically. In a basic relay there are three contactors: normally open (NO), normally closed (NC) and common (COM). At no input state, the COM is connected to NC. When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO.
By using proper combination of contactors, the electrical circuit can be switched on and off.
EBOT Temperature Sensor
EBOT temperature sensor uses LM35 Linear Temperature Sensor ,which based on semiconductor LM35 temperature sensor. It can be used to detect ambient air temperature. This sensor offers a functional range among 0 degree Celsius to 100 degree Celsius. Sensitivity is 10mV per degree Celsius. The output voltage is proportional to the temperature.
This sensor is commonly used as a temperature measurement sensor. It includes thermocouples, platinum resistance, and thermal resistance and temperature semiconductor chips. The chip is commonly used in high temperature measurement thermocouples. Platinum resistance temperature sensor is used in the measurement of 800 degrees Celsius, while the thermal resistance and semiconductor temperature sensor is suitable for measuring the temperature of 100-200 degrees or below, in which the application of a simple semiconductor temperature sensor is good in linearity and high in sensitivity. The temperature sensor is very easy to use and compatible with Ebot and Arduino shield.
Ebot 8 Pro
EBot Pro is an Arduino based microcontroller board that can be programmed through EBot Blocky Visual programing IDE. A number of compatible sensors are also available.
Smart , Easy and Innovative
Ebot is the smartest way of prototyping. Graphical programming, fully compactable sensors and mutually snapable plastics make your inventions faster, innovative and simple. Take your board. Attach sensor and plastic bricks. Program it using graphical software. Your Robot is READY !!
No more soldering, no more complicated wiring, no more programming errors, and no more searching for suitable mechanical parts.
Open and Universal
Ebot is based on most popular open source platform Arduino and Google’s Blockly. Users can refer, modify and improve our firmware and hardware. All the sensors and nodes are based on universal three pin connector, including VCC,GND, and SIGNAL. This makes the system compactable with a wide verity of existing sensors.
Ebot blockly is graphical programming software used to program Ebots. This software is based on Google Blockly. User can drag and drop nodes to workspace, modify its parameters and can finish programing. Nodes includes input devices, output devices, code flow control elements like delay, logical statements like if and many more.
Smart phone App
Ebot Blockly is also available in smartphones with same user interface as desktop software. User can drag and drop blocks and press ‘Play’ button to run the code. There is no need of compilation or waiting to download code. EBot is smart enough to work without compilation.
Multimedia nodes are available here as well. This helps user to open and control audio, video and images in the phone in synchronous with Ebot.
DataLab is the graphical visualisation of real time sensor values. Both graph and gauge representations are available. Sensor data can be saved as an excel file as well. This even available in smartphone version.
Live control is a part of EBot desktop application, that helps user to control Servo motors, RGB LEDs, Buzzers, etc.. in real time . User can use UI controls in the software to change parameters like angle of servo, colour of RGB led and so on. These changes will be reflected in the hardware instantly.
There is an option to save different states (that includes different values for servos, buzzers and LEDs) and to loop through these saved states with user defined delays. This makes programming a Humanoid or Robotic Arm simple.
Wide range of Nodes
Ebot System comes with a wide range of sensors with its own 'blocks' in Ebot blockly. All the sensors including LCD and color sensors are developed with three pin connectors that can be directly plugged in to the Ebot motherboard.
These nodes are pretty enough to finish most ofyour projects. But you can really do more. Node maker wizard helps you to make your own nodes with your own libraries and code. Node maker is versatile and flexible enough to make almost all kind of available Arduino compactable sensors and more.
