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
- 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. Uses
TV for display, SD card for hard drive.
Desktop system costs $80 plus a TV. Pi Zero W is $10.
- 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.
