Parts for your project
Check the voltage and the connector of every module against your board before wiring anything up.
Logic levels
Many modern boards run at 3.3 V logic while older modules expect 5 V. Use a level shifter between them.
Power
Motors, LED strips and servos draw more current than a board's pins can supply - power them separately.
Starter kits
For a first project or a university course, a kit with a board, breadboard, jumpers and common sensors is cheaper than buying parts one by one.
Common questions about electronic components
3.3 V or 5 V?
ESP32 boards use 3.3 V logic; the classic Arduino Uno uses 5 V. Connecting a 5 V output straight into a 3.3 V pin can damage the board.
Which board should I start with?
An Arduino-compatible Uno is the easiest for learning. An ESP32 adds Wi-Fi and Bluetooth for connected projects.
