The DS18B20 is a digital temperature sensor that comes in two versions: a small TO-92 package, and a waterproof variant often encased in a metal tube with a long cable. Both provide digital temperature readings and can be used in many indoor and outdoor projects. The DS18B20 uses a protocol called 1-Wire, which only needs one data line to communicate and can support multiple sensors on the same pin.
Managing a project means making choices about how to plan, track progress, and handle unexpected changes. For years, traditional project management methods, often called waterfall, were the standard. These methods rely on detailed upfront planning, structured phases, and a clear path from start to finish. Every step is carefully mapped out, leaving little room for adjustments once the project is in motion.
The Arduino IDE (Integrated Development Environment) is the main tool used to write, edit, and upload code to Arduino boards. It's designed to be simple enough for beginners while still providing enough functionality for more experienced users. With a clean interface and compatibility with a wide range of boards, it's the go-to software for working with Arduino hardware.
After years of speculation and official hints, Nintendo has finally unveiled the Switch 2 through a first-look trailer and a promotional website. The new console introduces several small but significant updates compared to the original Switch, including a larger tablet with a bigger screen and slightly more rounded edges on the top and bottom. Notable hardware upgrades include an additional USB-C port positioned next to the headphone jack and a redesigned U-shaped kickstand on the back, which offers greater stability and supports multiple angles.
Guard clauses are a practical way to write cleaner functions by handling the unwanted cases first. Instead of nesting your entire function inside a stack of if conditions, you check for the early exits up front - returning or throwing as needed - and move on. It's a habit that keeps code flatter and easier to read. The structure becomes simpler, and it’s immediately clear what the function does and under what conditions it doesn’t even bother.
