These were used in the early phase and are included for reference: analog_read.ino: Reads sensor data (like voltages). digital_read.ino: Reads digital signals (like high/low states). digital_write.ino ...

This hurdle is easily overcome, but soon we are all faced with another issue: filtering noise from an analog signal. Luckily [Paul Martinsen] has put together a primer of three different ways to ...

Analog references are common to microcontrollers that have ADCs. Even if you’re not working with an Arduino, read through the article and use what you learn with your uC of choice.

The TEMT6000 is a cheap and small analog light sensor. The sensor typically comes on a breakout with only GND, VCC and SIGNAL pins. It is not a calibrated sensor however the signal is very useful for ...

The Arduino Mega2560 is based around the ATmega2560 8-bit, 16-MHz microcontroller. It has a total of 54 general-purpose input/output (GPIO) pins configured into six 8-bit and one 6-bit ports.

Data Acquisition System (DAQ) enables conversion of analog signal of physical system into a digital signal, making it more flexible for being processed by computer. Conversion of Analog signals which ...

Analog-to-Digital Converters (ADCs) come with different bit resolutions — such as 4-bit, 8-bit, 10-bit, and so on. For example, the Arduino Uno uses a 10-bit ADC.

This paper describes an Arduino Due based platform for digital signal processing (DSP) education. The platform consists of an in-house developed shield for robust interfacing with analog audio signals ...

GND of the module is the common (0V) connection. The digital signal output to be detected (usually marked as DO in the module) is applied to D2 input of the Arduino. Analog output (marked as AO) from ...
