Internet of Things (IoT) is revolutionizing the electronics industry. With more and more applications adapting IoT, it is important for the engineers of today to get acquainted with this technology. To help you with the same, Circuit Digest provides you with a large collection of free IoT projects for you to learn and recreate. The projects are built using the popular development platforms like Arduino, Raspberry Pi, ESP8266, STM32, MSP430, PIC amongst others. All projects are documented with a neat circuit diagram, code and demonstration video to provide a complete do-it-yourself experience. If you want more projects you can also check out our collection at Basic Electronics Projects | Arduino Robotics Projects | Arduino AI Projects | Arduino Home Automation Projects | Raspberry Pi Projects | ESP32 Projects
In the last tutorial, we look at the ESP Rainmaker platform and how we can use it with the ESP32 through Arduino IDE. In this part of the tutorial, we will investigate the RainMaker cloud platform a bit deeper and will try to add voice assistant functionality to it. This setup can be used to build IoT based Smart home, Voice controlled…
In this tutorial, we are going to look at the ESP RainMaker. ESP RainMaker is the end-to-end platform for the ESP chips from Experessif. It is designed as a successor to Experessif’s ESP Jumpstart platform. ESP RainMaker enables customers to quickly design, build and deploy AIoT solutions based on enterprise-level cloud computing without…
In the last part, Designing Smartwatch using ESP32, we have looked at how to interface the BH1750 ambient light sensor and the MAX30102 Heart rate sensor for our smartwatch project. In this part, we will be looking at how to interface some other types of sensors to our smartwatch. So, here we will be interfacing the HMC5883L/QMC5883L…
In the last part, DIY Smartwatch using ESP32, we have looked at how to make some interesting watch faces for our smartwatch project. In this part, we will be looking at how to interface some sensors to our smartwatch and will be interfacing the BH1750 ambient light sensor and the MAX30102 Heart rate sensor. We will be looking at…
Electrical appliances are all around us, starting from the indispensable charger of your smartphone to heavier appliances like room heaters, air conditioners, washing machines, and whatnot. Given the status quo of a looming global energy crisis, it is vital to have an understanding of the power consumed by these devices. While our monthly electricity bill gives us a…
In one of our previous projects, we interfaced SX1278(Ra-02) based LoRa module with Arduino and established communication among them. This was a very simple project and can come in handy for various applications. But what it can't do is establish communication with the internet for modern-day IoT applications. So in this project, we will be using the HPD13A which is…
When we are talking about LoRa, it's been more than 10 years since its first official launch and since that day LoRa is getting increasingly popular day by day. With so many IoT devices available, this low-power long-range wireless communication could fit into a plethora of applications. It is expected that by 2025 we will have 29 Billion devices connected to the…
Timer interrupts are crucial in the use of ESP32 timer interrupt programming projects for accurate timing control. If you want something to occur on schedule, ESP32 timer interrupts give you the accuracy required. A timer interrupt is a dedicated interrupt that operates as a high-precision clock, counting and controlling time events with microsecond precision. ESP32'…
IoT and home automation have come a long way since they first gained popularity in 2014, thanks to the debut of a game-changing IC called the ESP8266 by espressif systems. Today we know it as the nodeMCU module and in many of our projects, we have used this IC to build many home automation projects where our focus was on building AC Motor Speed Control or Phase…
As winter sets in, the air hanging over us thickens with smoke and gaseous emissions from burning fields, industrial factories, and vehicular traffic, blocking out the sun and making it hard to breathe. Experts say that the high levels of air pollution and COVID-19 pandemic can be a dangerous mix that can have serious consequences. The necessity for real-time monitoring of…
There are several soil monitor sensors available that can be easily interfaced with the Arduino or other Embedded modules and can be programmed for different types of projects such as Smart Agriculture Monitoring System. The problem is not having a combined, retrofit module that can easily be used in different projects or applications as needed…
Nowadays, Security system is one of the most researched fields and with increasing security threats, companies are launching new smart security products to combat these threats. IoT is an added advantage in this field which can automatically trigger an event, like calling the police, fire brigade or your neighbor, in case of any emergency. We previously built many security…
