So if you’re knee deep in an Arduino-based project and you want to constantly monitor all of the micro’s pins, what’s the best way to go about it? [Jonathan Clark] from LVL1 in Louisville ...

Unfortunately, the AD9833 doesn’t have a way to control amplitude, something which is pretty important in a function generator. So [Faransky] uses a X9C104P 100KOhm 8-bit digital potentiometer ...

For example, ATmega328P (Figure 13-2, Arduino Uno and Nano) and ATmega32U4 (Figure 10-2, Arduino Leonardo, Micro or Pro Micro) Arduinos have hysteresis built into the input side of digital IO pins (as ...

Each card includes information like voltage, pin diagrams, and more. They're incredibly easy to read and a great reference guide when you're first getting started with Arduino.

Arduino-compatible ATtinys with more pins Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate ...

The UDOO contains both and ARM cortex-A9 CPU and the hardware on a Arduino DUE. This includes 54 digital I/O pins, an optional SATA connection, and a number of other pin-outs and connectors.
