Stepping Into the 16 bit World with the Microchip 16 bit PIC24F16KA102 Family Microcontroller

Stepping Into the 16-bit World with the Microchip 16-bit PIC24F16KA102 Family Microcontroller

One of the commonly asked questions when we move to the bigger and powerful 16-bit microcontroller is do we really need it? As the 8-bit microcontroller is already suite almost all of our needs from a simple blinking LED to more sophisticated embedded application such as robotics. Despite the debate whether to use the 8-Bit

The LM324 Quad Op Amp Line Follower Robot with Pulse Width Modulation

The LM324 Quad Op-Amp Line Follower Robot with Pulse Width Modulation

Designing a simple and yet functional Line Follower Robot (LFR) is always a fascinating and challenging subject to be learned, the LFR actually could be implemented in many ways start from a simple two transistors to a sophisticated PID (Proportional, Integrate and Differential) which take advantage of the programmable feature of microcontroller to calculate the

Mid Range PICMicros

Bit-Banging Serial Interfaces for the Low-End and Mid-Range PICMicros using PIC16F84

When I designed the “YAP” for the “YAP” PICMicro programmer presented in “Programming and Customizing the PIC Microcontroller”, I felt that the serial interface provided in “execution mode” of the programmer would be very useful for people developing their own software. With this interface, the user could input new values into the PICMicro application or

Logic Probe Plus

Logic Probe Plus using PIC12F683

This project is based on a probe logic states, capable of measuring levels from TTL (5v) to state levels of PLC’s (24v). For this we have employed the use of the PIC 12F683 microcontroller, which by its nature is capable of operating at low voltages, in this case 3vcc, besides having analog inputs and internal

Interfacing the Microchip PIC18F Microcontroller Master Synchronous Serial Port MSSP to various I2C Devices

Interfacing the Microchip PIC18F Microcontroller Master Synchronous Serial Port (MSSP) to various I2C Devices

The Inter-Integrated Circuit or I2C (read as I square C) bus has been introduced in 1980 by Philips, and has become a de-facto world standard for data exchange between Microcontroller and various devices such as temperature sensor, ADC (analog to digital converter), DAC (digital to analog converter), I/O expander, EEPROM, and many more. With more
