If you’ve run out of I/O pins ... buttons make up an R2R resistive ladder. When one of them is pressed, it completes the circuit for a voltage divider. The results are measured by the analog ...

Fascinated with electronic projects and want to build your own? Arduino boards can most definitely help with that. These microcontroller boards are designed to send and receive data to and from ...

The Arduino Mega's PWM ... function as normal digital pins that can switch a component either fully on or fully off, they can also be used to generate simulated analog values through a technique ...

The joystick shown in Figure 10-2 is basically two potentiometers and a button that allow us ... between 0 and 1,023 when read by the analog pin of the Arduino. This number sends a pulse to ...

The button states could easily be read by using an Arduino’s analog input ... the Arduino would have to keep the pins as inputs until a steering wheel button was pushed, the pin changed ...

The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

If you want to make your Arduino project more compact, an Arduino Shield is the answer. The Arduino Shield is a neat piece of hardware that sits on top of your Arduino board. It is typically designed ...
