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 ...

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 ...

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 ...

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 ...

Spread the love“`html Connecting sensors to Arduino opens up a vast array of possibilities for hobbyists and professionals alike, transforming ideas into functional prototypes and projects. Whether ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

An Arduino is an open source platform which is used to build electronic projects. It consists of hardware (physically programmable circuit board or microcontroller) and software or IDE (Integrated ...

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 ...
