Hello readers, we hope you all are doing great. Welcome to the 1st lecture of Section 4 in the ESP32 Programming Series. In this section, we will interface the ESP32 module with common Embedded modules(i.e. LCD, Keypad, RTC etc.).
In today's tutorial, we will interface ESP32 with a 16x2 LCD and will display data using both Data Mode and I2C Mode. LCD is the most commonly used embedded module in IoT Projects. It is used to display different types of data i.e. sensor readings, warning messages, notifications etc.
Before going forward, let's first have a look at what is LCD and How it works:
16x2 LCD Module
LCD(Liquid Crystal Display) is a type of electronic display module that is used in a wide variety of applications and devices such as calculators, computers, mobile phones, ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at a detailed Introduction to LM35. LM35 is a type of commonly used temperature sensor, that can be used to measure temperature with an electrical output compared to the temperature in (°C). In can measure temperature in a better way than a thermistor.
LM35 is used in industries and commercial buildings where high accuracy of temperature measuring is needed. I will give you a detailed overview of this temperature sensor in today’s post where we will have a look its pinout, working, protocol, etc. I will also share some links of projects where I have interfaced it with Arduino or other microcontrollers. If you have any questions please ask in the comments, I will resolve your queries and will gu ...
Hi Guys! Glad to see you around. I welcome you on board. In this post today, I’ll walk through the Introduction to LM2575.
LM2575 is a step-down voltage regulator mainly used to step down the voltage. It is also known as a buck converter and is used to drive load under 1A. In the customized output version of the buck converter, you can set the output voltage as you like better. It comes with an extremely good load and line regulation and is available in fixed output voltages with 3.3V, 5V, and 12V.
I suggest you read this post all the way through, as in this post I’ll detail the Introduction to LM2575 covering the datasheet, pinout, features, and applications of this component LM2575.
Let’s get started.

Hi Guys! Happy to see you here. Thank you for viewing this read. In this post today, I’ll walk you through the complete Introduction to BC550. BC550 is a low-power low-frequency general-purpose bipolar transistor. It is mainly used to drive loads under 100mA. BC550 carries three terminals where a small current across one terminal is used to control the large current across the remaining terminals. It’s primarily used for amplification and switching purposes. Transistors are critical components and building blocks of modern electronic circuits. Bipolar junction transistors are divided into two main types named NPN transistors and PNP transistors. The BC550 falls under the category of NPN transistors and is available in a plastic TO-92 case. I sugge ...
Abstract: This paper is written to represent a web-server based real-time weather monitoring system implemented using the ESP32 module. The system is designed to measure the weather conditions like temperature, pressure, humidity etc, in its vicinity. This system continuously provides real-time data (weather conditions) over limited or controlled areas, for example, agriculture fields, homes or a particular room, industries etc. Although we have satellites for weather monitoring but to perform research over a particular area, the data observed should be highly accurate which is not possible with satellites. To implement an IoT network we need to use a webserver to continuously store and display the real-time data which can be accessed globally. ’T ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to A1015. A1015 is a part of transmissive light sensing sequence which has a high competence GaAs Infrared light discharging diode which actions as the light stemming component, extremely sensitive phototransistor is used as the light sensing element. These two apparatuses are established so as in the opposite of each other, any materials fleeting among them are effortlessly sensed.
The A1015 is made in casing of TO-92. By seeing at its smooth side we can comprehend the three terminals impending out, these three terminals from left to right are emitter, collector and base. In today’s post, we will have a look at its fortification, ...

Update: We have created a new version of this library, which you can check here: Arduino Mega 2560 Library for Proteus V2.0.
Hello friends, hope you all are fine. In today's post, I am going to share Arduino Mega 2560 Library for Proteus. In the previous post, I have shared the Arduino UNO Library for Proteus and I have mentioned that I am gonna share more Arduino Libraries soon. Actually these days I am quite excited about this Proteus component designing and I am designing the Arduino boards as a starter. So, till now I have designed two Arduino boards in Proteus. First one was Arduino UNO which I have provided for download in previous post and today, I am going to share Arduino Mega 2560 Library for Proteus.
