Some beginner-friendly Arduino Uno projects you can get started with include an ultrasonic piano, a gesture-controlled system for VLC, and an automatic plant watering device. The analog input pins ...

[Damian Peckett] has implemented an Apple ][, its 6502 processor, and a cassette port, all on an Arduino Uno. If that wasn’t enough, he also uses a PS/2 keyboard for input and outputs analog VGA.

all contained in Arduino Shield Form-Factor (Uno and Leo/R3). Its creators explains more about their EnergyShield Arduino rechargeable battery and why they are looking for Kickstarter funding.

The Arduino 101 has the same dimensions as the Arduino Uno, and the pins are ... will provide a varied voltage input to the analog 0 pin to emulate a battery sensor. The point is to show how ...

However, when it comes to power inputs, the Uno seems to be the better option. Comparing the Arduino Uno and the ... idea to connect a switch for the battery, so you can turn the power on and ...

Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive ...

It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than others. For example, ATmega328P (Figure 13-2, Arduino Uno and Nano) and ATmega32U4 (Figure 10-2, Arduino ...

It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a standard 9V battery pack, as usual. As you may well know, ...

It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than others. For example, ATmega328P (Figure 13-2, Arduino Uno and Nano) and ATmega32U4 (Figure 10-2, Arduino ...
