According to the SX1509 datasheet, digital outputs default to high on initialization. This is the opposite of what's typically expected for Arduino outputs. With the current library setup, it appears ...

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 ...

You have been approached by a company who wants to build a simple device controlled by a muscle activity sensor. There is no specific requirement which muscle group you should use for your control ...

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 ...

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 ...

Global positioning system (GPS) synchronised clocks give accurate time. These clocks are universal and commonly used at railway stations, bus stands and airports. These are widely used for military ...

The OV7670 camera module with Arduino programming has always dominated the electronics industry, as it has lots of applications, such as visitor monitoring systems, surveillance systems, attendance ...

Studying animal behavior in the lab requires reliable delivering stimulations and monitoring responses. We constructed a comprehensive behavioral platform (ArControl: Arduino Control Platform) that ...

Fire Alarm Systems are very common in commercial building and factories, these devices usual contain a cluster of sensors that constantly monitors for any flame, gas or fire in the building and ...
