iCircuit vs Learn Arduino Programming

iCircuit is the premier iPhone and iPad app for designing, simulating, and learning analog and digital electronics. Its advanced simulation engine provides real-time, always-on analysis so your circuits stay powered and live, just like working with real components. Use it like a CAD tool: add components, wire them up, and set their properties. But iCircuit is unlike typical CAD apps because it is always simulating. You do not stop to take a measurement or spend time configuring reports. Instead, you just play with the circuit as you normally would, with the power on. Build circuits with over 300 components, from simple resistors and LEDs to programmable Arduinos (Uno, Nano, Mega, ESP8266, ESP32), Raspberry Pi Pico boards running real MicroPython and CircuitPython, PIC microcontrollers, and 60 4000/7400-series digital ICs (more available with Pro). Connect elements, adjust values, and instantly see the results. BUILT-IN TEST EQUIPMENT • Multimeter: Probe any point to read voltage, current, and power • Oscilloscope: Track multiple signals with touch-controlled time scale, stacked/unstacked views, FFT analysis, and Bode plots • Gauges: Visualize voltages, currents, and frequencies directly in your circuit • Signal generators and configurable sources EXTENSIVE COMPONENT LIBRARY • Raspberry Pi Pico and Pico 2 running genuine MicroPython and CircuitPython firmware • Programmable Arduinos (Uno, Nano, Mega, ESP8266, ESP32) • Programmable PIC microcontrollers (assembly and HEX files, more available with Pro) • Power: Voltage regulators (78xx, LM317), sources, dependent sources, power jacks, and simulated antennas • Analog: Resistors, capacitors, inductors, diodes, BJTs, MOSFETs, thermistors, triodes, and tetrodes • Digital: Logic gates (AND, OR, NAND, NOR, XOR), JK and D flip-flops, and 60 4000/7400-series ICs (180+ available with Pro) • ADCs and DACs • Sensors and displays: LEDs, 7-segment, NeoPixels, matrix displays, thermistors • Electromechanical: Motors, servos, SPST/SPDT and DPST/DPDT switches, push buttons, relays, and speakers SPICE, VERILOG, AND VHDL Import vendor SPICE models and subcircuits and use them as components. Write Verilog or VHDL in the HDL element and wire it to the rest of your circuit. CREATE CUSTOM ELEMENTS Build sub-circuits and custom elements to componentize your designs and create reusable modules. Share your custom elements with others via the iCircuit Gallery. AUDIO SIMULATION Hear your circuits. Speakers, buzzers, and microphones produce real audio output. Perfect for students learning electronics, hobbyists prototyping projects, and engineers validating designs, all without burning out a single component. ABOUT ICIRCUIT PRO (OPTIONAL) iCircuit is a complete app with a one-time purchase. iCircuit Pro is optional and adds extra components (including more PICs and a larger 4000/7400 IC library) and helps fund ongoing development. Pro is not required for core simulation or everyday circuit design. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Learn Arduino Programming brings structured Arduino lessons, quizzes, coding practice, and study tools together in one easy-to-navigate learning experience. Explore Arduino fundamentals, follow your progress, and build a consistent study routine at your own pace. **EXPLORE ARDUINO STEP BY STEP** Start with an introduction to Arduino and move through lessons covering boards, microcontrollers, electronics, programming, and sensors. The app organizes its learning content into 16 chapters and 160 lessons, making it easy to find your next topic and see what you have completed. Topics shown in the app include: - What Is Arduino and How It Works - History of the Arduino Platform - Types of Arduino Boards - Arduino Ecosystem Overview - Understanding Microcontrollers - Installing Arduino IDE - Setting Up Your First Arduino Board - Electronics Fundamentals for Arduino - Arduino Programming Basics - Digital Input and Output - Analog Input and Output - Working with Sensors **LEARN WITH LESSONS AND QUIZZES** Read lessons in a clear chapter-by-chapter layout. Each lesson displays its estimated reading time, quiz count, and progress. Completed lessons are marked, while a Continue Reading label helps you return to a lesson in progress. Explore 320 quiz questions across the app's chapters. Use quizzes to revisit key concepts and check your understanding as you learn. **PRACTICE IN THE CODE EDITOR** Open the built-in code editor to explore programming examples and a coding workspace. The editor screen shows language options including Dart, Python, JavaScript, and C++, along with quick examples such as Hello World, Fibonacci Series, Factorial Number, Calculator App, and List Operations. The workspace includes files and a Run control. **SEE YOUR LEARNING PROGRESS** The Overall Progress screen brings your learning statistics together. Check completed lessons, overall completion percentage, chapter and quiz totals, daily learning streak, and completion rate. See which lessons are completed, in progress, or not started. **FIND LESSONS FASTER** Use Search to explore lessons, topics, and categories. Browse popular topics, view recent searches, and find relevant learning content without scrolling through every chapter. **EXPLORE COMMUNITY HELP** Visit Community Help to browse popular questions and shared answers. Search community questions, explore topics, and discover solutions from community discussions. **BUILD A DAILY LEARNING HABIT** Create a learning schedule that fits your routine. Choose a study time, select a duration of 15, 30, or 45 minutes or 1 hour, pick repeat days, and enable a reminder. The schedule screen helps you organize regular learning sessions. **MAKE THE APP YOUR OWN** Settings give you control over your learning experience. Adjust appearance with Dark Mode, choose app language and text size, manage notifications, and access bookmarked lessons and your notes. **WHY LEARN WITH THIS APP?** - 16 organized chapters - 160 lessons across Arduino topics - 320 quiz questions - Lesson reading times and completion indicators - Coding workspace and quick examples - Search for lessons, topics, and categories - Overall progress, completion rate, and learning streak - Community questions and answers - Daily study schedule and reminders - Notes, bookmarks, and learning preferences Whether you are starting with Arduino basics or returning to a topic you want to review, Learn Arduino Programming offers a structured place to read, practice, search, and track your learning. Explore the lessons, test your knowledge, and keep moving forward one topic at a time.
