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 ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some… ...

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 ...

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.

By introducing the Arduino OPTA platform for rapid development and deployment of automation systems, this article examines the features offered by Analog Devices technology integrated into the module, ...

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 ...

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.

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 ...
