This is the most comprehensive graphical programming and developing tool based on Arduino. WhenDo is the most sufficient way to learn about Arduino and every basic programming logic. WhenDo is compatible with all the Arduino chips that have Bluetooth 4.0 module . Significant Features: 1. Graphical programming In this graphical programming language, user just need to drag condition and execute blocks and freely combine them. This development tool applies many amusing functions that the Arduino can accomplish in WhenDo. 2. Clear and meticulous logic Each sentence involves three elements: When block ( condition setting), Centre Node (combine When & Do block) and Do block ( execute setting ). Besides, the whole interactive User Interference environment is a big loop, which repeatedly run the program statements. 3. Cloud server compile Excellent file transfer and compile based on a Ubuntu server. Remote access to various libraries to improve its capability. 4. BLE download Wireless download the program through blueTooth 4.0 Arduino devices.

Learn Coding for Kids is a first programming app for young beginners: short Python lessons, block coding games and turtle drawing that turns a few lines of code into a picture on the screen. It is built for children who have never written code, and for the parents who want to see real progress rather than a video about programming. DRAW WITH PYTHON IN THE FIRST MINUTE The very first step needs no typing experience. Your child runs a tiny program and a turtle draws a star, stroke by stroke. Tap a different program and a square, a flower or a rainbow spiral appears. Change two numbers and the picture changes. This is how a loop starts to make sense before the word "loop" is ever used, and this first drawing runs right on the phone, with no internet needed. A STEP-BY-STEP PYTHON COURSE FOR KIDS 20 short courses and 80 bite-sized lessons take a child from "What is coding?" to writing real Python: • What computers are and what code is (no typing at the start) • Algorithms: thinking in clear, ordered steps • Printing messages, variables and simple math • Text, true or false, and making choices with if and else • Loops and counting with range • Lists, dictionaries and random numbers • Functions as reusable "recipes" • Turtle graphics, simple animations and nested-loop patterns • A mini project: build your own quiz game Each lesson is small enough for a short attention span, and every idea builds on the one before it. BLOCK PLAYGROUND: CODING GAMES AND PUZZLES 41 block puzzle levels where a cat, a frog, a robot or a dragon has to reach the goal. Children snap together blocks like move, jump, repeat, "if blocked" and "repeat until goal", press play and watch their program run. Levels earn stars, get harder step by step, and train computational thinking the same way the lessons do, just with blocks instead of text. PYTHON MISSIONS 60 small missions in easy, medium and hard: say hello to the computer, count jellybeans, build a star staircase, check even or odd, find the hidden toy. Each mission is a short, concrete goal your child finishes in code and checks in the app. A REAL CODE EDITOR When your child is ready, the built-in code editor lets them write and run Python on the phone and see the output. Their programs can be saved and opened again later. TOOLS THAT HELP IT STICK • Mini quizzes and flashcard review • A cheat sheet and example programs • Notes, saved lessons and "My Codes" • A daily streak and progress that shows what was learned • 22 app languages, so lessons can be followed in the family's own language EARN A CERTIFICATE At the end of the path, children can take an exam and earn a certificate with their name on it, a nice way to celebrate finishing a Python course. WHY PARENTS CHOOSE IT • Real Python early on, not only drag-and-drop • Block games for younger or less confident learners • Clear, short lessons that fit into a busy day • A gentle pace: many new ideas start as a picture or a puzzle • A parental gate in front of purchases and links that leave the app FREE TO START, PRO FOR THE FULL PATH The first course, the first Block Playground levels and the first coding missions are free, so your child can try real coding before you decide. CoddyKit Pro unlocks every course and lesson, all 41 puzzle levels, all 60 missions, and the exam and certificate. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in your App Store account settings. Learn Coding for Kids is part of the CoddyKit family of learning apps. It is a friendly way to learn to code: STEM learning at home, a first programming course for kids, and block coding games in one place.
