Introduction  You’ve probably heard about the terms “pulse generating” or “PWM” before, or maybe even worked with them—for example, which Arduino pins can generate PWM pulses. They are widely used in Electronics for lots of things. Some of these applications include synchronizing digital systems, controlling engines and timers, as well as adjusting LED color and brightness. This concept also has its own place in all switching power supplies and other methods of controlling voltage and power...

An Introduction to WX-101W Module The WX-101W module is one of the oldest and most popular thermostats on the market. It's a great option for temperature control in many projects due to its several features and simple design and use.It also has a digital seven-segment display that shows the temperature value with a resolution of 0.1°C. In addition, there are three buttons for controlling and settings, as well as an output terminal for turning on/off an external actuator such as a heater.To work with th...

Introduction ESP chips and NodeMCU boards have a crucial role in some areas, such as smart homes and electronics, because they have good features and a reasonable price. These boards are quite useful for various projects. It is also very easy to work with them. The Arduino IDE software may even be used to program NodeMCU boards.Words like “ESP” and “NodeMCU” might be a bit confusing for beginners who have just stepped into this field as to whether they mean the same thing. Therefore, we will fir...

A thermocouple module is a package that contains a K-type thermocouple and a display. It can measure and display high temperatures up to 800°C. What is a Thermocouple? A Thermocouple is a well-known electrical component for measuring temperature. This component also has two dissimilar electrical conductors that form an electrical junction. The voltage produced by the thermocouple is highly dependent on the temperature of the thermocouple. Using this voltage, we can m...

Introduction You must have come across the terms “square pulse generation” and “pulse width modulation” (or PWM), and you probably have worked with them—for example, which pins of Arduino (or any other microcontroller) can generate PWM pulses. Pulse width modulation is a technique for generating square pulse signals with desired features, which are widely used in different areas of Electronics. Some of these applications include controlling the color and brightness of LEDs, controlling engines...

Overview A potentiometer is a device that can change its resistance by moving a contact along a fixed resistor. It has three terminals: one connected to each end of the resistor and one connected to the movable contact. By adjusting the position of the contact, the potentiometer can divide the input voltage into different output voltages [Read more in Wikipedia]. Potentiometers work by creating a voltage drop across the resistor that is proportional to its length. For example, if the input voltage is 10...
