.. them, so I decided to make my own software and hardware. For hardware, I choice PIC16F877 that I had spare in my drawer, PIC firmware was written in MikroC, and software was written in Delphi 7. You can download full schematic, code for ...
This project is pretty cool for a few reasons, and driving a huge LED matrix with a single 8-bit controller is just one of them. The idea was born when I bought 120 LEDs of the wrong type, and decided to do something with them. With that many LEDs, ...
.. by multiplexing [1-4] . A Some other Design Ideas use additional logic, which increases cost and size [5]. Figure 1. Two PIC pins drive six LEDs Note that VDD must be between 2V 3V: for example, if LED2 is ON (Table 1), LED4 and LED6 will ...
.. an internal comparator with selectable values for the internal voltage reference V REF . The majority of Microchip 8-bit PIC microcontrollers in the mid-range family feature one or two internal comparators with just this. As a simple and ...
.. fast-executing program and simple circuit allows a PIC MCU to linearize a thermistor and accurately determine and display the temperature from its measured resistance. ...
Application Note TB3103 October 2013 Mihnea Rosu-Hamzescu This technical brief describes a synchronous buck power supply, based on the PIC16F753 using 100% analog control for output regulation. The implementation has the advantage of not using any ...
.. is an AC Watt Meter which can measure the real power consumption of a device connected to the 230Vrms/50Hz mains line. The PIC microcontroller PIC18F252 from Microchip collects the voltage and the current information with the help of ADCs and ...
.. a voltage divider to adjust the maximum battery value (4.2 V at the end of the charge) to the 3.0 V maximum voltage on the PIC pins. At this time, duration of the battery is around 10 days. With the actual software, there isn’t any low ...
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 ...
.. Meter on PIC16F1936. So this version is battery powered and comes complete with a 3D-printed case. It uses a mid-range PIC microcontroller, a Microchip PIC16F1936 (Figure 2). Not that there’s much special about this model, I just ...
