RS232 EIA232F TTL and USB Adaptor Examples Tx and Rx Baud Rate, Misc Asynchronous Tx Loop-Back Test $50 Robot UART What is the UART? The UART, or Universal Asynchronous Receiver / Transmitter, is a feature of your microcontroller useful for communicating serial data (text, numbers, etc.) to your PC. The device changes incoming parallel information (within the microcontroller/PC) to serial data which can be ...

Tutorial: Building cool projects with MCUs (Part 3) As we proceed onto the third portion of this microcontroller tutorial, let’s first revisit what we have accomplished thus far. In Part 1, we defined what a microcontroller actually was. I wanted to get everybody on-board (no pun intended) for this, so I started from scratch. Feel free to jump back there if you need a refresher. Then in Part 2, we looked at ...

We are now in the fourth part of the microcontroller tutorial. We have a microcontroller circuit diagram ready. It’s time to make a circuit board. I love this part. This is the “magical” step that takes the idea we started with and turns it into something real. But let’s recap. So far we have learned: Part 1: What is a microcontroller? Part 2: How to choose your microcontroller? Part 3: How to design a circ ...

This servo controller generates a signals to control a standard servo motor (I used a Futaba servo but you can use any servo) using the 12F675 microcontroller.  You can type a text command into a serial terminal e.g Hyperterminal to set the position of the servo. The project software works slightly differently to the previous one as interrupts are used for pulse timing - this lets it both service the serial ...

An alternative to using a transistorized H-Bridge circuit is the L298 Dual Full-Bridge Driver. It is very easy to control and it doesn’t require any calculation. Simply knowing your motor’s required current and the IC’s current capacity is enough. For a price though.In order to learn this, you need to first download the IC’s datasheet file. Simply google “L298 Datasheet” or click the link —> L298 Datashe ...

PIC is a family of modified Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1650[1][2][3] originally developed by General Instrument's Microelectronics Division. The name PIC initially referred to "Peripheral Interface Controller".[4][5] PICs are popular with both industrial developers and hobbyists alike due to their low cost, wide availability, large user base, exte ...

In this tutorial, I will show you how to write a very simple program. I am assuming that you have written ladder logic before, and that you have some basic familiarity with microcontrollers, but that you have never used LDmicro. If you don't know very much about ladder logic or PLCs, then the plcs.net tutorial might be helpful to you. Our device will have one pushbutton, and one LED. At startup, the LED wil ...

Hi welcome to my 4th chapter of PIC18F4550 programming. Here we are going to learn another methodology or technique for programming a pic18f microcontroller which would be helpful in future while dealing with complex coding. We are going to define our own header file. We are also going to see the Source Code and will understand the importance, benefits of programming a microcontroller this way on Mplab ide. ...
