An Arduino library for I²C GPIO-expander with sample code. To operate the port for input, the IO pins can be configured bit by bit. The config bit for output is 0 and input is 1. When the bit 0 to 3 ...

Pins of microcontroller can be used as inputs or as outputs. Output on a microcontroller (Arduino): We use pin of a microcontroller as output , when we want to give command - information to an ...

A cheap USB-programmable analog output is great for setting intensities, power levels, or general analog signalling in many experimental contexts. There are lots of solutions when you want one or two ...

In this tutorial, we will develop a 5V variable voltage source from Arduino Uno. For that, we are going to use ADC (Analog to Digital Conversion) and PWM (Pulse Width Modulation) features. This ...

If you are an electronic enthusiast like me who wants to tweak around with different electronic circuits, having a decent Function Generator sometimes becomes mandatory. But owning one is a problem ...

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

Arduino has taken the product “maker” world by storm and one of the more popular Arduino modules is the Analog Devices AD9851 DDS waveform generator. An Internet Web search for “Arduino DDS” showed ...

Check out the this colourful but BASIC use of Arduino... I flagged this one in the "Tweets of the Week" section of Electronics Weekly magazine, from the Arduino team, but it's worth highlighting in a ...

We’ll admit it, we’re all spoiled. A few bucks can now buy a computer that would have been the envy of everyone back in the late 1970s or early 1980s. So it’s no surprise that [krallja] was able to ...

Arduino is a perfect mindless slave. Give it a job and it performs the task endlessly without defaulting even for a nano second. On the other hand, Raspberry Pi, or Raspi, is a computer that has a ...
