- 3. MICROPROCESSORS MICROCONTROLLERS A microprocessor is a computer processor which incorporates the functions of a computer’s CPU on single IC. It is a hardware that can process logical code A microcontroller is ‘all in one’ , the processor , ram ,rom and IO on the one chip EMBEDDED SYSTEMS An embedded system is some combination of computer hardware and software, either fixed in capability or programmable, that is designed for a specific function or for specific functions within a larger system.
- 4. Digital pins can read or write 2 possible values HIGH or LOW (1 or 0), whereas Analog pins can read a value between 0 to 1023 and write a value between 0 to 255.

- 14. ThingSpeak is an Internet ofThings (IoT) platform that lets you collect and store sensor data in the cloud and develop IoT applications You can create sensor logging applications, location tracking applications, and a social network of things with status updates.
- 15. TWEET USING ARDUINO Arduino is the thingspeak client which sends HTTP request to the thingspeak server Register with thingspeak.com Link your twitter account with the app thingtweet Paste the generated api- key in your Arduino code Connect your Arduino board to the thingspeak sending http request Execute a set of commands Yee.You have tweeted from your Arduino board
- 16. Upload sensor data to cloud Register yourself on thingspeak.com Create a channel for viewing the live data that is being uploaded Copy the write api key to your Arduino code Connect your Arduino board to api.thingspeak.com You will see a graphical representation of the data uploaded by the sensor to the cloud server.
