LM324 IC or Infrared Proximity Sensor

LM324 Photodiode sensor or Infrared Proximity Sensor (Line following Robots’ Sensor)

Hi friends!!!!
Today we will talk about LM324 IC or Infrared Proximity Sensor.

Line follower robot needs sensors to detect the line to follow. Robot can detect line in two ways. One is using vision sensor (Robotic eye) or using Photo diode sensors as the line is drawn in single surface with two differentiating colors. Robotic eyes are too expensive so we will have to use use LM324 Photodiode sensor Or Infrared Proximity Sensor.

Now we are going to build a sensor that will sense the reflective objects from a certain distance. This will work as proximity sensor. The

Arduino LED blinking

by

Hello readers!!!

Yes you are here because you’ve chosen this techiehunters’ posts and clicked on Arduino LED blinking project. So let’s collect the important components list.  We will need an IDE for coding on Arduino. You will get the IDE from this site. First download the installer then install the software. Remember don’t plugin the Arduino while installing this software. if you have done the installation of the software then come to the components.

Components List:

1.  Arduino                                           —-  1pc
2.  LED                                                   —-  1pc
3.  Jump Wire (male to female)  —-  2pcs

First of all connect the LED with Arduino. Connect the Arduino pin 13 with

Basic electronics idea and Notation

by
Hello friends!!!

I am a hobbyist. I have done lots of school projects when I was a secondary school student. Today I am going to share my ideas on electronics and I will obviously try to give you a concrete guideline, “How to understand and work with Electronics” in the most possible ways.

What is Electronics?

Electronics is the study of electrons. In electronics we study about the flow
