Here are some interesting and useful websites and tools:
- This site generates random circuits and their solutions for practice:
- Designing Electronics That Work – Free eBook from industry engineer on designing electronics that actually work in products
- Circuit simulators:
- Falstad (Shows current flow and can simulate arduino as well)
- CircuitLab (<– This is the best for creating circuits for lab reports)
- Multisim
- EveryCircuit Shows the current flow
- PHeT Basic circuit simulators
- General Tip: Power your robot motors with a different power supply than your control circuit.
