Arduino

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

Port Registers

• Port Manipulation
• Use only if:
  • You need to turn pins on and off very quickly, meaning within fractions of a microsecond
  • You need to set multiple output pins at the same time
  • You're running low on program memory
  • Otherwise use digitalRead() and digitalWrite() for more readable, portable code.
• DDRx - data direction register (r/w)
  • You will only see 5 volts on these pins however if the pins have been set as outputs using the DDRx register or with pinMode().
• PORTx - data register (r/w)
• PINx - Read all of the digital input pins at the same time - read only
