The Arduino Platform and C Programming (Week 4)

Write a program that allows the user to control the LED connected to pin 13 of the Arduino. When the program is started, the LED should be off. The user should open the serial monitor to communicate with the Arduino. If the user sends the character '1' through the serial monitor then the LED should turn on. If the user sends the character '0' through the serial monitor then the LED should turn off.
If you do not have an Arduino, you can use the web-based Arduino simulator at www.tinkercad.com. You will need to create an account for free. There are instructional videos on that website that will teach you how to use the simulator.

>>>

#define BAUD_RATE 9600
char incomingByte = ' ';
void setup(void)
{
Serial.begin(BAUD_RATE);
pinMode(LED_BUILTIN, OUTPUT);
}
void loop(void)
{
if(Serial.available() > 0){
incomingByte = Serial.read();
//Serial.println(incomingByte);
if(incomingByte == '1'){
digitalWrite(LED_BUILTIN, HIGH);
//Serial.println("Led is ON");
}
else if(incomingByte == '0'){
digitalWrite(LED_BUILTIN, LOW);
//Serial.println("Led is OFF");
}
}
}

Introduction to the Internet of Things and Embedded Systems (Week 2)

1.        Identify two embedded systems that are sold on the market today and analyze their interfaces. >>>      DIGITAL CAMERA       A digital camera is very good example of Embedded system.       Cameras that we use today are smart and have a lot of features that were not present in early        cameras all because of embedded system used in them.       A digital camera has basically three functions, to capture image which we call data, to store            image data, and to represent this data.       Today images are stored and processed in form of digital data in bits.           HOME SECURITY SYSTEMS       Home security systems has another good example of Embedded systems.       These systems have several features just as checking for fire or gas leakages, and...

The Arduino Platform and C Programming (Week 1)

Image
1.         Install the Arduino IDE on your computer. Compile the "Blink" example, upload the example to the             Arduino board, and make sure that the LED blinks. Use the  www.tinkercad.com ​ simulator if you                 do not have the Arduino hardware.            Take and upload a screen shot that shows the "Done compiling" message and the byte number                 information in the message area. >>> 2.       Install the Arduino IDE on your computer, compile the "Blink" example (review Lecture 3.2 for a                  refresher). Then, upload the example to the Arduino, and make sure that the LED blinks. Use                    the ww...

Why Downloading Speed Is Less ?

Telecom companies says that you will get internet speed of 16Mbps. But when you download a file, you get speed only of 2MBps. Have you ever wondered what is the reason behind this ? Bits & Bytes Internet speed is measured in 2 units that most people don't know - MBps or mbps. See the capital and small "B". The value of 1b (bit) & 1B (byte) is given below. This means that 16Mbps is equals to 2MBps. 8 bits = 1 byte 16Mbps = 2MBps Reason   Telecom companies use smaller unit Mbps for advertising & attracting users. and when you use internet the speed gets divided by 8.
