Circuits & Schematics - Arduino - 2

By using this simple capacitor-network circuit and software, designs using the Arduino Uno need only two I/O pins to read a hex-switch decoder, leaving the remaining pins for other functions. A pulse-width-modulated (PWM) signal and the RC-charging ...

Part 1 - Arduino Version. Schematic, Sketch and PCB General information Schematic diagram Printed Circuit Board (PCB) Arduino Sketch Highlights Conclusion Downloads References General information The second version of the controller is made on a ...

Massimo Gottardi EDN The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure control to achieve this. ...

General information In this article we will talk about a simple device that I designed for automatic control of additional LED lighting in the kitchen. Kitchen renovating and complete replacement of kitchen cabinetry are main reasons for ...

I’ve just finished a little Arduino project. It’s a shield for the Arduino Uno that lets you measure inductance. This is a functionality that I found missing in just about any digital multi meter. Yes, there are specialized LCR meters ...

Boris Landoni Let’s expand RaspberryPi functionalities with a shield that is compatible with the Arduino pinout and with an onboard analog to digital converter with 16-bit resolution. Further expansions that we will present in the future will ...

Part 1 Input Card The input cards come in several types, each tailored to a different type (or types) of input. The first input card we designed is capable of measuring temperature through either a thermistor or thermocouple. Work on the next input ...

PID stands for proportional-integral-derivative controller. This is a device used in control systems or simply to control other devices or other electronic systems. The main function of this controller is to help regulate or maintain the level of ...

Part 1 - Schematic Part 2 - Software Optimising the line drawing algorithm The first versions of my driver code featured the Extremely Fast Line Drawing Algorithm (EFLA). It seemed to perform well and so I didn’t turn my attention to ...

Part 1 - Schematic The software drivers My previous Nokia QVGA reverse engineering efforts that you can find documented extensively on this site have left me with a flexible and expandable driver that will make a good base from which to add support ...
