KY-017 Module : PinOut, Equivalent, Specifications, Interfacing, Working, Datasheet & Its Applications

May 5, 2025 By WatElectronics

KY-017 Module

A switch that uses a small amount of mercury within a sealed glass tube to detect tilting is known as a mercury tilt switch. In 1922, Louis Austin Merritt Phelan invented a mercury switch through a glass envelope. After that, a more advanced mercury switch with a tubular glass envelope was invented in 1937 by Harold Olson. Whenever the switch tilts, then mercury will move and break the circuit. This is an electrical switch that opens & closes an electrical circuit whenever a small amount of … [Read more...]

KY-023 Joystick Module : PinOut, Features, Specifications, Types, Interfacing & Its Applications

March 27, 2025 By WatElectronics

Joystick Module

The first ‘Joystick technology’ was introduced in the early 20th century for use in aircraft. So this was patented by Ralph Baer in 1944 who invented the first video game console. So joysticks were used widely in video games in the years 1970s & 1980s. Joysticks are used as controlled devices in elevators & aircraft ailerons. So these are first used on the Bleriot VIII aircraft of Louis Bleriot in combination with a foot-controlled rudder bar on the tail for the yaw control surface. This … [Read more...]

Thermal Sensor : Working, Types, Interface with Arduino & Its Applications

October 21, 2022 By WatElectronics

Thermal Sensor

Most of the electronic & electrical components are rated to work in certain temperature ranges. But, the performance of these components can get reduced once the temperature increases from a specified range. Once the temperature crosses the maximum acceptable limit, then components will get damaged because of thermal runaway or heating. So, thermal characteristics play an essential role when selecting different components for electronic circuits. Thermal sensors are used for maintaining … [Read more...]

Arduino Projects for Engineering Students

October 6, 2021 By WatElectronics

Arduino Projects

An Arduino is a development board designed with a combination of both hardware and software with open source access. Arduino projects were firstly started at Interaction Design Institute Ivrea (IDII). The board consists of a microcontroller with is pre-programmed and an integrated development environment (IDE). This IDE helps in writing the code and dumping it on the hardware board. These boards are employed in a various electronic appliance that communicates with other technologies such as IoT, … [Read more...]

What is LCD 16X2 : Pin Configuration & Its Working

August 8, 2021 By WatElectronics

LCD 16 X2

In LCD 16x2, the term LCD stands for Liquid Crystal Display that uses a plane panel display technology, used in screens of computer monitors & TVs, smartphones, tablets, mobile devices, etc. Both the displays like LCD & CRTs look the same but their operation is different. Instead of electrons diffraction at a glass display, a liquid crystal display has a backlight that provides light to each pixel that is arranged in a rectangular network. Every pixel includes a blue, red, green … [Read more...]
