What is Industry 4.0?

  What is Industry 4.0 and what are some of the technologies that are driving it? Industry 4.0 is a term that refers to the fourth industrial revolution, which is characterized by the integration of digital technologies, such as artificial intelligence, cloud computing, big data, the internet of things, robotics, and 3D printing, into the manufacturing sector. Industry 4.0 aims to create smart factories that are more efficient, flexible, and responsive to customer needs and market changes. Some of the technologies that are enabling Industry 4.0 are: - Artificial intelligence (AI) : AI is the ability of machines to perform tasks that normally require human intelligence, such as reasoning, learning, decision-making, and problem-solving. AI can help optimize production processes, improve product quality, reduce costs, and enhance customer satisfaction. - Cloud computing: Cloud computing is delivering computing services, such as servers, storage, databases, software, and analytics, over t

Log sensor data in the cloud

The Cloud 

"The cloud" refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies do not have to manage physical servers themselves or run software applications on their own machines.

The cloud enables users to access the same files and applications from almost any device, because the computing and storage takes place on servers in a data center, instead of locally on the user device. This is why a user can log in to their Instagram account on a new phone after their old phone breaks and still find their old account in place, with all their photos, videos, and conversation history. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive.

For businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact for small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally, because employees and customers can access the same files and applications from any location.

Turn LED On and Off Through LDR

  LDR An LDR ( Light Dependent Resistor ) is a component that has a (variable) resistance that changes with the light intensity that falls upon it. This allows them to be used in light sensing circuits. A photoresistor is made of a high resistance semiconductor.

Temperature sensor

About the LM35 The LM35 is an inexpensive, precision Centigrade temperature sensor made by  Texas Instruments . It provides an output voltage that is linearly proportional to the Centigrade temperature and is, therefore, very easy to use with the Arduino. The sensor does not require any external calibration or trimming to provide accuracies of ±0.5°C at room temperature and ±1°C over the −50°C to +155°C temperature range. One of the downsides of the sensor is that it requires a negative bias voltage to read negative temperatures. So if that is needed for your project, I recommend using the DS18B20 or TMP36 instead. The TMP36 by Analog Devices is very similar to the LM35 and can read temperatures from -40°C to 125°C without any external components Note that the sensor operates on a voltage range of 4 to 30 V and that the output voltage is independent of the supply voltage. The LM35 is part of a series of analog temperature sensors sold by Texas Instruments. Other members of the series i

MQ2 Gas Sensor

 About Gas Sensor The MQ series of gas sensors use a small heater inside with an electrochemical sensor. They are sensitive to a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino. The MQ-2 Gas Sensor module is useful for gas leakage detection in homes and industries. It can detect LPG, i-butane, propane, methane, alcohol, hydrogen, and smoke. Some modules have a built-in variable resistor to adjust the sensitivity of the sensor. Note:  The sensor becomes very hot after a while, don't touch it! Required  Arduino UNO Breadboard MQ-2 Gas sensor module Red, Green led 5mm 220 Ohm Buzzer The connections are pretty easy: The MQ-5 sensor Pin-> Wiring to Arduino Uno A0-> Analog pins D0-> none GND-> GND VCC-> 5V other components Pin-> Wiring to Arduino Uno D13-> +ve of buzzer GND-> -ve of buzzer D12-> anode of red light D11-> anode of green light GND-> cathode of red li

Seven Segment Display Interfacing with Arduino

Seven-Segment Introduction  Let’s start the main part of this tutorial by answering a question: what is a seven-segment display? As its name suggests, a 7-segment device consists of 7  light-emitting diodes . These light-emitting diodes are arranged and packed inside a single display with a specific pattern in mind. If this pattern is controlled in a specific way by turning on and turning off LEDs, a seven-segment device will display a unique number. There is also an extra eighth LED on a seven-segment display which is used to display dots. This dot is sometimes used as a decimal point when we want to display a fractional value.  The picture below shows a seven-segment display and its pinout. The string of eight LEDs on the left side shows the internal connection and a picture on the right side shows how these LEDs are arranged to make a seven-segment display. Pin3 and 8 are common pins. These pins are used to provide either 5 volts or ground in common-anode and common cathode type dis

Mini Oscilloscope via Arduino Nano

What is an oscilloscope?   An  oscilloscope , formerly known as an oscillograph, is an instrument that graphically displays electrical signals and shows how those signals change over time. It measures these signals by connecting with a sensor, which is a device that creates an electrical signal in response to physical stimuli like sound, light, and heat. For instance, a microphone is a sensor that converts sound into an electrical signal. Oscilloscopes are often used when designing, manufacturing, or repairing electronic equipment. Engineers use an oscilloscope to measure electrical phenomena and solve measurement challenges quickly and accurately to verify their designs or confirm that a sensor is working properly. Scientists, engineers, physicists, repair technicians, and educators use oscilloscopes to see signals change over time. An automotive engineer might use an oscilloscope to correlate analog data from sensors with serial data from the engine control unit. Meanwhile, a medical

Fade an LED

AnalogWrite uses  pulse width modulation (PWM) , turning a digital pin on and off very quickly with different ratio between on and off, to create a fading effect.

Fire Alarm with arduino

Flame Sensor A  flame detector  is a sensor designed to detect and respond to the presence of a flame or fire. Responses to a detected flame depend on the installation but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system. The IR Flame sensor used in this project is shown below, these sensors are also called  Fire sensor modules  or  flame detector sensors  sometimes. There are different types of flame detection methods. Some of them are Ultraviolet detector, near IR array detector, infrared (IR) detector, Infrared thermal cameras, UV/IR detector, etc. When fire burns it emits a small amount of Infra-red light, this light will be received by the Photodiode (IR receiver) on the sensor module. Then we use an Op-Amp to check for a change in voltage across the IR Receiver, so that if a fire is detected the output pin (DO) will give 0V(LOW), and if the is no fire the output pin will be 5V(HIGH).
