Microcontrollers

Microcontrollers are small computers that can easily be interfaced to real-world sensors and effectors. They are inexpensive and easy to program, making them ideal for a variety of maker projects.

• Arduino: $25, credit-card size. Easy to plug in to. Shields plug in for capabilities such as internet.

• Arduino Pro Mini: $10 ($2 on eBay). Thumb-size, requires soldering.

• Flora: $20. Wearable Arduino, designed to be sewn into garments.

• Teensy: $20. Thumb-size, requires soldering. More powerful processor than Arduino.

• Raspberry Pi: $35. Runs Debian Linux. Has plugs for internet, keyboard, mouse, TV for display, SD card hard drive. Desktop system costs $80 plus a TV.

• Starter Kits: $80 - $100. Includes a processor board, plugboard, wires, components, book of projects.

• Sensors: buttons, pots (potentiometers or volume controls), light, sound, temperature, tilt, motion, GPS, touch, muscle, camera, joystick, etc.

• Effectors: lights, motors, relays, sound, displays.
