Arduino Language

• Arduino language reference
• analogRead() - analogRead docs
  • 0-4095 for 12 bits
  • On ATmega based boards (UNO, Nano, Mini, Mega), it takes about 100 microseconds (0.0001 s) to read an analog input, so the maximum reading rate is about 10,000 times a second.
• analogWrite() - AnalogWrite docs
• analogWriteResolution() - analogWriteResolution docs
