Circuit simulator game is a virtual simulation game that allows you to create, design, and test electronic circuits without the need for physical components. You may be given specific objectives or constraints that customers must meet with their circuit designs. Fun and interactive circuit builder with real animated component models. How To Play: - In this simulation game, the customer arrives at your electronics store and needs a specific circuit designed for his project. - You want to make sure that you can provide them with the best possible circuit design to meet their needs. - Start by selecting the appropriate components from a virtual toolbox, including resistors, capacitors, and transistors. - Then, you can drag and drop these components onto a virtual breadboard or circuit board, and connect them using virtual wires. - As you design the circuit, the simulator will provide real-time feedback on voltage, current, and resistance. This will allow you to test the circuit and make adjustments as needed until you get it just right. During simulation, you can check voltages, currents, and many other variables. Check signals on multichannel oscilioscope and tune your circuit in real time! Features: - One-finger control, simple and easy gameplay. - A variety of tools, components, and devices that players can use to build their circuits, including resistors, capacitors, transistors, and more. - A virtual workspace where players can drag and drop components and connect them using virtual wires. - Fun and engaging way to learn about circuit design while also improving problem-solving and critical thinking skills. - Different modes of play, such as free play, challenges, and missions, allow players to experiment with different circuit configurations and learn at their own pace. - Circuit analysis tools such as oscilloscopes, voltmeters, and ammeters to help players analyze and troubleshoot their circuits. Overall, a circuit simulator game can be a valuable tool for electronics enthusiasts and professionals alike. It allows you to quickly and easily design and test circuits without needing to physically build them, making it a great solution for situations where time, resources, or component availability may be limited.

About

Circuit Detective

Features
Read full description

Step into your electronics workshop and learn to solve faults, one measurement at a time. Circuit Detective combines a diagnostic game with a virtual 3D laboratory. Inspect components, follow circuit traces, place your probes and test your ideas against measurements. 77 MISSIONS TO BUILD YOUR SKILLS Start with resistors, LEDs and switches. Then explore capacitors, diodes, transistors, rectification and signals. Measure, calculate, choose a component or identify a fault. INVESTIGATIONS AND GUIDED PROJECTS Finish the progression with four investigations: measure, find the fault and check your repair. Three guided breadboard projects take you step by step through building a circuit. After each successful mission, explore the schematic and the explanation of your result. HANDS-ON VIRTUAL INSTRUMENTS Use a multimeter, a two-channel oscilloscope, a function generator and an adjustable power supply. Rotate around circuit boards, zoom in on components and inspect the solder side. A WORKSHOP FOR EXPERIMENTS Practice diagnostics and repairs, replace components and build circuits on a virtual breadboard. UNDERSTAND AS YOU PLAY Read lessons, component datasheets and hints. Use the built-in calculator to work through your measurements. Your progress is saved on your device. ONE PURCHASE, THE COMPLETE GAME All missions and the workshop are included. No ads, subscription or in-app purchases. Play offline without creating an account. Available in English, French, Spanish, German, Portuguese (Portugal) Traditional Chinese and Japanese on iPhone and iPad. Circuits are educational simulations: measurements and components are modeled for learning.
