  1. Abel Raynus EDN A microcontroller requires dc operating power in the 2 to 5.5 V range, an amount that a battery or a secondary power source can easily supply. However, in certain situations, a microcontroller-based product must operate directly ...
  2. Francois AUGER Philippe Fretaud EDN Many previous Design Ideas [1, 2] have shown how to use the Charlieplexing technique [3] to drive as many LEDs as possible with a minimum number of I/O lines. This Design Idea shows how you can drive three LEDs ...
  3. Andreas Freiherr VishayOpto Creating a “Magic” Cat Doorbell with the TSSP4P38 Proximity Sensor Leonie and her family live in a building with seven other families. Like many cats, Leonie loves to explore her surroundings, and after ...

  4. Ricardo Jiménez and Juan C. Ángeles Electronic Design A basic microcontroller can be used to convert a sensor's analog output into a pulse train, thereby making the output compatible with standard digital I/O ports. When the need ...
  5. Stephen Woodward EDN An inexpensive way to implement high-resolution digital-to-analog conversion is to combine microcontroller-PWM (pulse-width-modulated) outputs with precision analog-voltage references, CMOS switches, and analog filtering ( ...
  6. Part 1 Software The software for the datalogger is download section (PIC_DATALOG_V00d). I use Mikroc Pro PIC compiler from mikroElektronika , the libraries of this compiler are great! Especially the FAT32 library, it allows to manage the micro SD ...
  7. Part 1 - Hardware: Schematic, PCB and case. Hi all! I’m continuing here with the last board I design and now I’m continuing testing. It’s a battery-powered small datalogger based on a PIC18F2620 microcontroller (Figure 1). The ...
  8. Ioan Ciascai EDN Reading quadrature encoder signals at high speeds (e.g., 1 MHz, or, 1 m/s with a resolution of 1 um) often requires dedicated hardware. This Design Idea shows a simple scheme to accomplish this function using only an ATtiny2313A ...
  9. Les Hughson EDN The ATMega168 is a great general purpose 8-bit AVR microcontroller from Atmel . It has 23 GPIO pins, but sometimes (as I have found) you can run out of I/O pins as your design grows. This happened to me recently when, of the 23 GPIO ...
  10. Boris Landoni Part 1 - Specification and Schematic Operation The receiver provides for the control of the two channels by a 433 MHz remote control with MM53200 / Holtek HT12 encoding or a compatible one. Each channel is ...
