Circuits & Schematics - Interfaces - 5

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 ...

There are many TFT modules available on the market that are designed to connect directly to an MCU to provide a full colour graphical display, just search ebay for “tft module” to see what I mean. Unfortunately for Arduino users the ...

Aruna Rubasinghe Matrix keyboards are common as an input device in microcontroller-based projects. A conventional way of connecting a matrix keyboard to a microcontroller is to use multiple I/O pins of the MCU. The MCU then uses a scanning ...

This shield allows to connect an Arduino with DMX equipment (Figure 1). It implements the RS485 interface to adapt the electrical levels needed for DMX connection. This shield has been designed with flexibility in mind and allows the user to choose ...

Temperature-indicator and temperature-based products have generated wide interest. There are numerous applications for such devices with many possible solutions, each with its own advantages and disadvantages. This idea discusses a sensor interface ...

Part 1 Zoltan Gingl Two configurable analog ports allow you to connect many sensor types using two three-input connectors, each of which has a ground pin (Figure 4). One ground pin provides 3.3V power, and the other outputs the buffered reference ...

A precision analog acquisition system fits in your pocket. Zoltan Gingl, University of Szeged, Szeged The circuit in this Design Idea combines a mixed-signal microcontroller, a USB UART (universal asynchronous receiver/transmitter), and a novel ...

Economical alternative to original Arduino ethernet shields, allows data rates up to 10 Mbps and is achieved with a traditional assembly components. One of the most interesting shield that you can mount on the Arduino platform is certainly the ...

Rajendra Bhatt, Nepal The use of a graphical LCD (GLCD) drastically changes the look of your project. It provides more freedom for presenting data than the HD44870 based character LCDs. Today we will see how to interface a KS0108 (name of the ...

On my desktop PC I have a speakers and a headphones. Usually I use headphones, but when I need to switch to speakers I need to physically plug in speakers instead of headphones to my PC’s soundcard. I wanted to solve this problem for a long ...
