Learn how to initialize and manage EEPROM settings on Arduino to store data like user preferences, calibration values, or ...

Read through the init() function and the corresponding sections of the AVR datasheet if you’ve never done any low-level initializations of an AVR chip; that’s how it’s done without Arduino.

The basic functions of the Arduino IDE – pinMode, digitalRead, digitalWrite, and analogRead – are available. Most of the WiFi functions work just like the WiFi shield library.

1. Arduino Board: The heart of the project. An Arduino Uno or similar board will work perfectly. 2. Rotary Encoder: Used for adjusting the frequency and amplitude of the generated signals. 3.

"We've tried to learn a lot of the lessons [from Arduino]," Kridner said. "They have these really simple functions. If I want to set a pin high, it's digital write, pin number and high.

If you’d like to get more specific, Michael Klements’ Arduino-based scanner lets you quantify colors in numerical RGB values via a TCS34725 sensor.
