Combining the dual-core processing capabilities of the ESP32 with the reliability of GSM connectivity, the ESP32 GPS tracker with SIM800L is the perfect solution for real-time position tracking. Unlike Wi-Fi-only solutions, this ESP32 GSM GPS system will work anywhere there is cellular coverage, because it does not rely on Wi-Fi. The NEO 6M GPS module with ESP32, in…

Unlike other ESP Development Boards, the ESP32-CAM has no USB connector to connect it to a computer. This might be confusing for beginners when they try to program this development board for the first time, so in this article lets learn how to program the ESP32-CAM module using the Arduino IDE. Before we start, I assume you know the basics about the ESP32-CAM module…

Object counters or product counters are important applications used in industries, shopping malls, etc. They count objects or products automatically and so reduce human efforts. In this tutorial we are going to design a simple object counter circuit without using any microcontroller.

In this tutorial we learn to Enable UART communication with PIC Microcontroller and how to transfer data to and from your Computer. So far, we have covered all basic modules like ADC, Timers, PWM and also have learnt how to interface LCDs and 7-Segment displays.  Now, we will equip our self with a new communication tool called UART which widely used in most of the…

IR Transmitter and IR Receiver are commonly used to control electronic devices wirelessly, mainly through a remote. TV remotes and AC remotes are the best example of IR transmitters. TV generally consists of TSOP1738 as the IR receiver, which senses modulated IR pulses and convert them into electrical signal. Here in our circuit we are building IR remote and its receiver.…

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'…

Li-Fi (Light Fidelity) is an advanced technology that allows transferring data using optical communication, such as visible light. Li-Fi data can travel through the light and then be interpreted on the receiver side using any light-sensitive device, like an LDR or a photodiode. Li-Fi communication can be 100 times faster than Wi-Fi. In this comprehensive guide, we'll…

I have created a Raspberry Pi based Project, an Automatic Library Book Management System Project. Let me tell you first how this project plays an important role in the real world. As you are all aware of the current pandemic situation and now colleges/schools have been re-opened, it is important to maintain social distancing. In some colleges or…

The mileage and performance of an Electric Vehicle depends on the capacity and efficiency of its Battery Pack. To maintain the battery pack in full health is the responsibility of the Battery Management System (BMS). A BMS is a sophisticated unit in an EV which does a lot of activity like monitoring the cells, balancing them and even protecting them from…

In this tutorial we are going to make a Touch Capacitive PCB using an ATMega328P IC to control neo pixel led strip. We will include some features such as music reactive mode, random animation mode, and RGB controlling mode on our PCB. So far, we've made a touch capacitive piano where you can find the basics of touch capacitive technology. And now in this…

In this project, we are going to build an animatronic eye with Arduino. I got the idea to create an animatronic eye while looking for new project ideas online, and this project immediately caught my attention. First of all, it looks cool and has a simple mechanism and I learned a lot about mechatronics while working on this project. A big shout out to Will Cogley for…

While Internet of things (IoT), Industry 4.0, Machine to Machine communication etc are getting increasingly popular the need for wireless communication has become incumbent, with more machines/devices to speak with one another on the cloud. Designers use many wireless communication systems like  Bluetooth Low Energy (BLE 4.0), Zigbee, ESP43 Wi-Fi Modules, 433MHz RF…
