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 fine and having fun with your lives. In today's tutorial, I am going to share a new Proteus Library named as Flex Sensor Library for Proteus. I am quite excited while sharing this one because we are the first one to design this library and share it online. Although, I wanna add one thing here that most of the flex sensors are analog sensors and their resistance changes over bending and believe me I have tried my best to design an analog sensor but despite the efforts we couldn't so I am sharing a digital version of Flex Sensor. So, its not gonna detect how much its bent but it will detect whether its up or bent. So, I thought to share it with you guys. It's better to have something than nothing. You should also have ...
Hello friends, hope you all are fine and enjoying life. Today's post is about removing a small error named as Recognition Failed in EasyVR, which I encountered while working with EasyVR shield with Arduino UNO. I have posted a complete project on EasyVR shield around a year ago in which I haven't mentioned this error because at that time I didn't encountered it. But today while working with EasyVR shield, I encountered this problem so I thought to share it with you guys.
EasyVR shield is a voice recognition module which is used for recognizing voices and operating accordingly. Using this module, one ca quite easily control anything using voice. In the previous project, I have controlled a robot using voice commands like when I say Forward then it ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to elaborate you, how to make Arduino Projects for beginners. Before gong into the detail of this tutorial first of all I would like to explain you a bit about Arduino. Arduino is an open source micro controller. A lot of help is available online so its user friendly hardware. Most of the students prefer to do work on this device.
Arduino is a low cost high performance device. Due to its cost effectiveness and open source feature it is commonly available in the market these days. An amazing thing about Arduino is that students can take help online with a lot of examples regarding any of the task. There are thousands of Arduino projects are available online f ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give a detailed discussion on Introduction to LM4040. LM-4040 is specially designed for an accurate micro-power shunt voltage reference. These voltage references includes the standards of 2.5V, 3V % 5V respectively. LM-4040 has three different grade A, B and C grades and they have o.1%, o.5% and 1% tolerances respectively.
This device is available in different packages and each package has different individual dimension which will be explained later. We can achieve an excellent performance from this device when it is operating at the current ranging from 60uA to 15mA and its temperature coefficient is 20 ppm per degree. In order to maintain good stability ...
Hi Guys! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to Arduino MKR NB 1500.
The Arduino MKR NB 1500 is mainly developed for working in remote areas where no power or internet connection is available. This board is based on a SAMD21 Cortex-M0+ 32bit low power microcontroller and comes with an operating voltage of 3.3V.
Admit it.
The Arduino board is a remarkable addition to the development of many automation and embedded projects. These boards are incorporated with a series of digital and analog pins that can be connected with the expansion boards or other breadboards.
Most of the Arduino boards are integrated with 8-bit Atmel AVR microcontrollers. And all these boards incorporate ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Introduction to ADC0804. In electronic engineering different modules used to conversion of analog signal into a digital signal. These tools are recognised as analog to digital converter or ADC. Thes signal converter also used to find the value of input current and voltage. Normally the output of these converters are 2 binary numbers but other values are also possible. These analog to digital converter are available in different structure scheme but mostly they are available in integrated circuits packaging.
The working ability of these signal converter depends on their bandwidth and signal to noise ration (SNR). Their bandwidth can be fined by their sample r ...
Hello friends, I hope you all are fine and enjoying. I have been working on a project these days and one portion of my current project includes the NRF24L01 Arduino Interfacing. So, I thought why not share this knowledge with you people, I hope you will learn something new and more interesting. If you don't know much about it, then you should have a look at Introduction to NRF24L01.
Few days ago, I have also posted a tutorial on XBee Arduino Interfacing, in which we have seen how to make wireless communication between two XBee Modules which is also an RF module. So, now we are gonna have a look at How to make Wireless Communication between two NRF24L01 modules. I hope you are gonna enjoy this nrf24l01 arduino Interfacing. Here's the video demonstr ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide you the discussion on Introduction to LM393. LM-393 has two internal operational amplifiers. These are internally frequency compensated. These are specifically designed to perform their tasks using a single power supply sources. LM-393 can also perform its operations properly by using split power supply. The current drain supply does not depend upon the magnitude of the power supply.
One of the most amazing feature of LM 393 is that ground is included in its common mode input voltage. Moreover, LM 393 has a lot of features e.g. wide voltage supply ranges, a very small current drain supply, low input offset current, low input bias current, output v ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a Traffic Signal Control using Arduino. Few days earlier, I have posted the same tutorial but it was Traffic Light Signal Using 555 Timer in Proteus ISIS and today we will do the same thing but using Arduino programming. Its quite a simple but good starting project on Arduino. So, if you are new to Arduino then must give it a try.
Traffic Signal Control is quite a usual thing. We see traffic signals daily on our roads and usually engineers are asked to design such projects in their initial semesters. If we look at the traffic signals then we can see they are simply turning ON and OFF lights at some fixed regular intervals. and the pattern is quite simpl ...
