Hello readers, hope you all are doing great. In this tutorial, we are going to discuss a mechanism that allows users to update the ESP32 with a new program wirelessly or over the air (without using a USB cable to upload a new program).
Over-The-Air (OTA) programming
Fig. 1 ESP32 OTA
OTA programming is the mean by which a product manufacturer or product service provider can update the features or functionality of the device wirelessly or over the air, after the device has been deployed in the field where connecting a cable or uploading the code serially is difficult.
One key advantage of OTA is that a single central node can send an update to multiple ESPs on the same network.
The device must have a provisioning client capable of receivin ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide a detailed discussion on Introduction to Laser Sensor. Laser sensor is basically an electronic device which we often use for the detection of accurate positions as well as small objects. Laser sensors transmit or radiate laser light. This laser light consists of light waves having same wave length. Due to this fact laser light travels in a parallel direction from the source emitting this light. Due to its travel in parallel direction it can be transmitted over long distances. This light is dangerous for the human beings.
We must avoid by looking directly into the light. It causes serious eye damaging effect and even can make anyone blind. As we ...

Hey Guys! I hope you all are doing great. In the previous tutorial, we studied the basics of Semiconductors, where we briefly discussed the PN Junction. Today, we are going to have a detailed overview of PN Junction.
But before getting into the details of PN Junction, we need to first recall a few concepts from the previous lecture:
Semiconductor Basics
As we know, the conductive power of a semiconductor material lies between a conductor and an insulator. So, it can act as a pure conductor as well as a pure insulator, depending on the applied conditions. Semiconductors are divided into two types:
Intrinsic Semiconductor.
Extrinsic Semiconductor.
Intrinsic Semiconductor
A semiconductor in its pure form is called an Intrinsic semiconductor. In this state, the outermost valan ...
