Arduino Lesson 8 - Analog Read

Interfacing with complex sensors requires more than just the "on" and "off" or "high" and "low" feedback that digital reads offer us. This is where analog reads come in. In this session we will learn how to use analog reads in the context of Infra Red sensors.
First we will print the values to the serial port and then I will show you how to apply your analog read function in a practical way.

Thank you so much, your tutorials are the best I've seen so far. Straight to the point so I don't lose attention. Opens a whole new perspective to my future Arduino tinkering. Thanks again.

You hack the arduino you are amazing thank you ❤

Superb Sir the best explanation I have seen in RUclips keep uploading projects also sir. Thank u

Nice bro thanks for teaching

Good for you

Thank You...

Can this be used to detect a specific sound from a microphone? I am designing a project to detect a specific sound and not react to any other sounds around it. Could I create a code that loops to find the specific digital values of that sound alone?

Thank you so much.why dont u post more vedios

Hi
but when i removing 5 v the ADC Continue read noise between 0 to 1023 . Is there a way to isolate this noise?

[@ashmiashiq1855]

plz provide your wiring of the infrared sensor...
i have searched the net but your custom made sensor couldn't be found....

[@benduino7327]

I can't attach images here, but google image "tcrt5000 wiring diagram" and you will find a similar schematic. Alter the resistor values or use a variable resistor to alter the sensitivity of the sensor :)

@@benduino7327 , thanks mate
i recently found one though is easier than i thought, plz confirm the connection if you have time..
supply voltage to (resistor+emitter) then ground
supply voltage to (resistor+ receiver) then signal emitter wire to analogue pin

I'm not sure your IR sensor is working correctly. As you finger approaches the sensor more IR is reflected back and the number should go up not down. I need to check the wiring and operation of my IR board. Possibly the sensor is just reading background IR illumination.

analogRead() gives random values when there is no any external input is given

How about a video on while loops?

IR sensor is a digital sensor, returning only values of zeros and ones. Why are you considering it analogue
