A few months back I took a look at some low-cost passive infrared (PIR) motion sensor modules. Since I am fond of sensors, I did a few sensor research and found out about Microwave radar sensors. Luckily, I found this interesting sensor in our new arrival lists, In this article, we are going to discuss […]

What is an Electromagnet???? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. The electromagnet is simply a large coil of wire wrapped around a piece of iron. Applications: (Pick-and-place systems)- This type of electromagnets are

As ultrasonic sensors started being used in cars as reverse parking sensors, manufactures started producing them in bulk which made them easily available in a wide variety of models at cheap prices. We at Probots (www.probots.co.in), sell a wide range of ultrasonic sensors which are easy and simple to interface with microcontrollers. Why is AJ

Introduction: Analog TDS Conductivity sensor is used for measuring the TDS value of the water, this TDS values define the cleanliness of the water. It can be used to check the quality of domestic water, hydroponic liquids, and in other fields of water quality testing TDS Pen is widely available to measure TDS value, but

The nRF52 DK board is excellent for testing and getting products with the nRF52 IC ready. It has an onboard nRF52 BLE IC which can be programmed as a beacon. It can also act as a programmer and be used to program an external nRF52 beacon. This is very helpful as external programmers are expensive.

Build direction: A snap fit built in the direction shown above will be much stronger. It’s important to consider building direction. If possible, try to avoid designing snap-fit cantilevers that are built up from the bed vertically (in the z direction) as these are inherently weaker due to the anisotropic nature of 3D printing. Add

Annular snap-fits The annular snap-fit utilizes hoop-strain to hold a pressed part in place. Common examples of annular snap-fits are bottle and pen caps. With annular snap-fits, it is possible to achieve a waterproof seal around the joint.For the rest of this article, the focus will be on cantilever snap-fits. In this joint the strength

So in this article there are three parts, which will give you a detail concept on snap-fits. Snap-fit joints are a quick and easy way of connecting two 3D printed components together using interlocking features. snap-fit is an assembly method used to attach flexible parts, usually plastic, to form the final product by pushing the

Modbus is a data communication protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers(PLCs). Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices for data transmission. An important point to pay attention to is that

In every project we used to build, we have always neglected the switch selection and struggled to find the perfect switch for the application at the end of the project. We have now learned our lesson and realized the importance a switch plays in both the functionality and appearance of the final product/project. All the
