Bench guides for Arduino and robotics

Use these practical references to check voltage, wiring, board selection, first power-up, and sketch flow.

Practical bench references

• Wiring basics for microcontroller projects — Plan separate power and signal paths, check logic levels, and select drivers for loads.
• Choose a board for the project — Compare board voltage, peripherals, memory, and software support against the project.
• First power-up checklist — Inspect wiring and supply limits before energizing a new prototype.
• How to read an Arduino sketch — Follow setup(), loop(), input decisions, timing, and output drivers.
