  1. The idea Ardusumo is a universal platform to build robots on wheels that can move around avoiding obstacles using infrared sensors and follow routes marked with dark lines on a white background (Figure 1). We have created Ardusumo to bring young ...
  2. 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 ...
  3. Frequency meter with some of quite good performance, capable of measuring frequencies from 1Hz to 10MHz (9,999,999 Hz) with a resolution of 1 Hz over the entire range. Ideal for function generators or as a standalone meter. It is cheap and easy to ...
  4. Zoran Mijanovic, Nedjeljko Lekic Part 1 - Schematic Let us look at the first shift register. The microcontroller drives CLOCK input directly. The same signal passes through the RC filter and drives DATA input D (Figure 5). The RC filter is formed ...
  5. Branislav Korenko and Marek Cerný, Slovak University of Technology, Bratislava, Slovakia EDN This Design Idea was realized for voltage/current measurement on a four-channel analog voltage source but has wide use in many other applications. ...
  6. Zoran Mijanovic Nedjeljko Lekic EDN This Design Idea shows how a single microcontroller port can drive a lot of output lines through shift register. In this case we use the shift register with strobe control to achieve perfect output line control. ...
  7. The objective of this project is to build an Arduino voice shield to empower thousands of voice related applications! All this mostly thanks to an integrated ISD1790PY chip (Figure 1). Figure 1. Voice Shield for Arduino This particular voice/TTS ...
  8. Vishwas Vaidya Thermocouples and their leads often have to detect open-circuit or short-circuit faults. However, it is very difficult to distinguish a valid millivolt temperature signal from an open/short-circuited thermocouple, which generates a ...
  9. Mehmet Efe Ozbek, PhD, Atilim University, Ankara, Turkey - August 17, 2012 EDN A previous Design Idea demonstrates how you can use a microcontroller to drive a piezoelectric buzzer at a high alternating voltage through a four-MOSFET circuit that ...
  10. Part 1 - Hardware The getting started will guide you with installing the required software on the pc. There are only two programs required before you can program the Simplecortex: the IDE and the driver for Windows to recognize the Simplecortex as ...
