Now day’s automation systems are everywhere whether its home, office or any big industry, all are equipped with automation systems. Restaurants/Hotels are also adopting recent automation trends and are installing robots to deliver food and tablets for taking orders. Using these digital menu cards like tablets, customers can easily select the items. This information will…

If you are planning on building a robot with DC motors then you will eventually learn that you need to control both the speed and direction of the motor if you want it to move it in a certain direction. And one of the best ways to do it is by using a L293D motor driver IC, because it's cheap, easy to use and with a bit of PWM support it can control both speed and…

The MPU6050 sensor module consists of an accelerometer and gyro on a single chip. It contains analog-16 bits in the digital converter for each channel. So it can capture the x, y, and z channels at the same time. The sensor uses I2C-bus to interact with Arduino or any other microcontroller. The MPU-6050 sensor module used in many applications like drones, robots, motion…

Want to give your project a sense of sound! Then follow along because in this project, we are interfacing a sound sensor to build some interesting projects with it. The KY-038 sound sensor we are using uses a condenser-type microphone to detect sound waves, which gives us a perfect balance of stability and reliability. So in this article, we decided to interface…

The ESP32-CAM is a tiny board that comes with a camera, microSD card, and of course the ESP32 microcontroller for less than ten dollars. It also has Wi-Fi and Bluetooth capabilities making it an ideal choice for IoT projects. But working with the ESP32-CAM board can be an intimidating task because it requires an external programing board and it isn't as…

In this project, we will be exploring AD8232 ECG sensor working and will connect it with Arduino to run some analysis on the resulting waveform for medical diagnosis. We will also see different types of ECG sensors in the market, the lead placement for a 3 lead ECG system, and the various medical conditions that can be…

Most advanced electronics PCB assembly lines have pick and place machines to pick components from an SMD reel and place it on a PCB. But this is not possible when you are doing medium-scale production or using THT (through-hole type) components on your PCB. This scenario holds true, in most low-cost board assemblies like LED drivers, transformerless power supplies, etc. In…

Today, we are going to build an Arduino weight machine by interfacing a Load Cell and an HX711 Weight Sensor with Arduino. We have seen weight machines at many shops, where the machine displays the weight just by placing an item on the weighing platform. So here we are building the same weighing machine by using Arduino and Load cells, having a capacity of measuring up to…

ATtiny85 Microcontroller Chip is an affordable and powerful alternative to other Arduino microcontrollers, especially when you want to shrink your project down. The chip features 8 pins out of which six are I/O (Including Reset) pins and two are power pins. But how do you program it as it doesn’t have a USB interface like other microcontroller boards? So in this article…

Hi guys, welcome to today’s post. One of the most fascinating thing about being a maker is knowing how to develop makeshift tools, you will never get stuck working on any project when you have that kind of versatility. So Today, I will be sharing how to build a Raspberry Pi based makeshift version of one of the most important tools in Electrical/Electronics engineering; The…

Many of us who have worked with Analog circuits would have often come across the terms voltage source and current source in a circuit design. While anything that provides a constant voltage like a simple 5V USB output or a 12V adapter can be considered as a voltage source, the term current source always seems to remain a mystery. And many circuits, especially the one…

There are many IoT clouds available to store and monitor the data from various sensors. With increasing popularity of IoT, more number of sensors are used every day and these sensors produce anonymous data which are useful to control other devices on the IoT network. These data can be studied further and used to modify design or improve the system performance. The…
