iDroidSim vs Learn Python | PythonBook

iDroidSim is a simple and powerful circuit simulator. Perfect for students new to electronics circuit design and construction, hobbyist and tinkerers and even seasoned professionals who want a quick, handy tool to perform electronics circuit design calculations. That's interactivity and innovation you can't find in best SPICE tools for PC. iDroidSim simulator solves basic resistive circuits using Kirchoff’s Current Law (KCL) in much the same way a student in a circuits class would,the simulator systematically forms a matrix in accordance with KCL and then proceeds to solve for the unknown quantities using various algebraic techniques such as Gaussian elimination and sparse matrix techniques. For non-linear components, such as the diode and BJT ,iDroidSim engine searching for the approximate solution by making an initial guess at an answer and then improving the solution with successive calculations built upon this guess. This is called an iterative process.iDroidSim simulation uses the Newton-Raphson iterative algorithm to solve circuits with non-linear I/V relationships. For reactive elements(capacitors and inductors),the iDroidSim uses numeric integration methods to approximate the state of the reactive elements as a function of time. iDroidSim offers the Trapezoidal(I'll add a GEAR method later) integration methods to approximate the state of the reactive elements. Although for most circuits, both methods will provide almost identical results, it is generally regarded that the Gear method is more stable, but trapezoidal method is faster and more accurate. iDroidSim for now can simulate: -Resistor -Capacitor -Inductor -Potentiometer -Light Bulb -Ideal operational amplifier -Bipolar junction transistor (NPN PNP) -MOSFET N-channel depletion -MOSFET N-channel enhancement -MOSFET P-channel depletion -MOSFET P-channel enhancement -JFET N and P -PN Diode -PN Led diode -PN Zener diode -AC current source -DC current source -AC voltage source -DC voltage(battery) source -CCVS - current controlled voltage source -CCCS - current controlled current source -VCVS - voltage controlled voltage source -VCCS - voltage controlled current source -Square wave voltage source -Triangle wave voltage source -AC ampermeter -DC ampermeter -AC voltmeter -DC voltmeter -Two channe oscilloscope -SPST Switch -SPDT Switch -Voltage controlled switch -Current controlled switch -AND -NAND -OR -NOR -NOT -XOR -XNOR -JK flip-flop -7 Segment Display -D flip-flop -Relay -IC 555 -Transformer -Graetz Circuit If you are making an oscillators you have to put a small initial value on some of the reactive elements.(see the examples)

Learn Python at your own pace with structured lessons, quizzes, and tools to keep your learning organized. Explore Python fundamentals, follow your progress, and return to the topics you want to study. Learn Python brings lessons, quiz questions, notes, and learning progress together in one place. Whether you're opening your first Python lesson or revisiting a topic, you can follow a clear chapter-based learning experience. EXPLORE PYTHON LESSONS Start with Python Introduction and work through lessons covering topics shown in the app, including: • What is Python? • Installing Python • Python IDEs • Hello World Program • Python File Structure • Syntax Basics • Python Comments Each lesson is presented within a chapter, with reading-time information and quiz questions. Move through the lesson list in an organized way and revisit individual topics whenever you need to. PRACTICE WITH QUIZZES Use the quiz questions associated with lessons to review what you've studied. The chapter overview displays quiz information alongside the lesson count, so you can see the learning material and practice opportunities together. FOLLOW YOUR LEARNING PROGRESS See how far you've progressed through a chapter with a completion percentage and progress bar. Lesson cards display individual progress, and completed lessons are clearly marked. A Continue Reading label helps you identify a lesson to return to. The chapter overview also brings together useful details such as completed lessons, quiz questions, and average reading time. Stay aware of what you've covered and what remains. KEEP YOUR STUDY MATERIAL ORGANIZED Take Notes Keep study notes accessible while working through your learning material. Bookmarked Lessons Return to lessons you've saved for later review. Recent Lessons Find recently studied lessons from your learning history. These tools make it easier to pick up where you left off and keep important topics within reach. EXPLORE THE CODE SECTION Access the app's Code section from the bottom navigation alongside Home, Search, Progress, Help, and Menu. Keep coding-related learning close to your lessons and study tools. SET UP YOUR LEARNING EXPERIENCE Make the app more comfortable to use with settings visible in the app: • Dark Mode for changing the appearance • App Language preferences • Adjustable Text Size • Notification settings • Learning Schedule for daily study goals and reminders Choose the preferences that suit your reading and study routine. LEARN IN A WAY THAT WORKS FOR YOU Python learning is easier to follow when lessons, practice, and progress are organized in one place. Open a chapter, read a topic, review quiz questions, and track completed lessons as you move forward. With Learn Python, you can explore introductory Python topics, keep notes, revisit bookmarks, and manage your learning schedule from a single app. CLEAR CHAPTER OVERVIEWS Before you open a lesson, the chapter header shows key details: chapter number, reading time, completed lessons, quiz questions, and overall progress. A separate summary highlights lesson and quiz totals and average reading time. LESSON-BY-LESSON TRACKING The lesson list keeps reading-time estimates, quiz counts, and progress percentages beside each topic. Completed lessons and lessons marked Continue Reading are easy to distinguish. STUDY AT YOUR OWN PACE Choose a lesson, return to bookmarked material, or open your notes while reviewing. Use the learning schedule to set study goals and reminders, and adjust text size or appearance to suit your preferences. FROM FIRST TOPICS TO REGULAR REVIEW Begin with introductory topics such as Python installation and your first Hello World program. Continue with file structure, syntax, and comments, then revisit what you've covered through quizzes and progress indicators. Start exploring Python lessons and make steady progress, one topic at a time.
