Direct current/Project basics

This is a guide to direct current electronic projects. Here are the basics to starting projects, and there are links to specific DC projects.

Common tools

 * Multimeter
 * Solder
 * Electronic board: breadboard, printed circuit board

Semiconductors
Diodes

Integrated circuits
Integrated circuits are chips that have basic circuits internally, and can be wired to externally for greater use.

555 timer
There are variants to the 555 chip for the same purpose but for more outputs: 556 chip. This chip is used to time circuits.

Audio amplifier
The LM386 is an audio amplifier chip.

Motors
BLDC

Open source hardware
Arduino

Wikiversity projects

 * Robotics Projects
 * Amplifier
