Create a Choice-based Text Adventure Game With Tinkercad Circuits

One of my fondest childhood memories is visiting my grandparent’s house and reading my uncle’s old collection of “Choose Your Own Adventure” books. While I always got stuck playing text-based computer adventure games with finnicky commands, I was hooked to the simplicity and variety of CYOA books (albeit the abundance of dramatic bad endings was …

How to Set Up an Ultrasonic Range Finder on an Arduino

Ultrasonic range finders are fun little modules that measure distance. You can use them to find the distance to an object, or to detect when something is near the sensor like a motion detector. They’re ideal for projects involving navigation, object avoidance, and home security. Because they use sound to measure distance, they work just as well in the dark as …

Low-cost current monitor tracks high dc currents

To measure high levels of direct current for overload detection and protection, designers frequently use either a current-shunt resistor or a toroidal core and Hall-effect magnetic-field sensor. Both methods suffer from drawbacks. For example, measuring 20A with a 10-mΩ resistor dissipates 4W of power as waste heat. The Hall-effect sensor delivers accurate measurements and wastes …

Understanding silicon circuits: inside the ubiquitous 741 op amp

The 741 op amp is one of the most famous and popular ICs[1] with hundreds of millions sold since its invention in 1968 by famous IC designer Dave Fullagar. In this article, I look at the silicon die for the 741, discuss how it works, and explain how circuits are built from silicon. I started …

Arduino ISP (In System Programming) and stand-alone circuits

We use an Arduino to program other ATmega without bootloader . This technique allows you to use all flash memory for code and make boards using new ATmega, cheaper than those with bootloader. The qualities that have made the success of Arduino are undoubtedly the open-source software, many libraries, a good hardware and a virtually infinite …
