In our projects are generally unaware of the passage of time—they lack an internal clock to track it. While this limitation is acceptable for most applications, there are instances where precise timekeeping is essential. In such cases, the DS1307 precision RTC module proves invaluable. It is ideal for a variety of projects, including clocks, timers, […]
What is USART? USART (Universal Serial Asynchronous Receiver Transmitter) is a widely used serial communication protocol that enables data transmission and reception over a single data line at a specific baud rate. This asynchronous communication technique does not require a separate clock line, as the sender and receiver agree on timing based on predefined settings. […]
If you’re looking to create a home burglar alarm, build a trail camera, or even add life to animated Halloween props that spring into action when trick-or-treaters arrive at your door, the HC-SR501 Passive Infrared (PIR) sensor is an excellent choice to consider. Its versatility and reliability make it an essential component for motion-detection-based projects. […]
All objects, including the human body, emit heat energy in the form of infrared radiation when their temperature is above absolute zero (0 Kelvin or -273.15 °C). This phenomenon is a result of the thermal motion of particles within the object. The hotter an object is, the more infrared radiation it emits. However, this […]
This versatile sensor not only identifies the presence of alcohol but also accurately gauges its concentration. Whether you’re looking to build a DIY breathalyzer to measure blood alcohol content or create a safety system that detects alcohol vapors, the MQ3 alcohol sensor is an ideal solution. With its sensitivity to ethanol and reliable performance, it’s […]
If you’re looking to measure temperature with an Arduino, there are a variety of sensors available, each suited for different applications. Some of the most popular options include the DHTxx series, DS18B20, LM35, and TMP36, among others. These sensors offer a range of features such as digital or analog outputs, precision, and ease of use, […]
