So if the USB To RS232 PL2303 TTL Converter Adapter does not have a DTR pin, we will have to manually reset the Arduino Board in order to upload the code. The way it works is by sending a reset signal (GND) to the reset pin using the DTR signal on the RS-232 interface.

The USB to RS232 chipset based TTL provides you an easy and convenient way to connect your RS232 TTL Devices such as Arduino boards to your PC via the USB port.ĭata Terminal Ready (DTR) is simply a control signal in RS232 serial communication, transmitted from data terminal equipment (DTE), like a PC, to data communications equipment (DCE), for example a modem, which will be used to indicate that the terminal is ready for communications and the modem can now initiate a communication channel.ĪutoReset is a feature, which enables us to upload the compiled sketch to the Microcontroller without pressing the reset switch. This is a compact circuit that will help us to translate the communication between PC and the microcontroller IC. USB To RS232 PL2303 TTL Converter Adapter So in order to program we will have to use another external circuit that will stand in between the PC and the microcontroller and help us to communicate back and forth between them.

There are boards like Arduino Pro Mini and Lilypad that are really small and less costly that don’t have the IC that facilitates the communication between the Arduino Board and the USB. Arduino Boards without built in USB circuitry

Once the code is uploaded, this chip will help the Arduino board to send messages back and forth between the Arduino and the PC. This is the chip that helps you upload your program to the microcontroller. This chip is what lets you connect your USB cable to the Arduino board and helps the ATMEGA IC to communicate with the PC via USB. In most of the boards, there is another chip, that acts as an intermediate between the PC and the main microcontroller IC. It is this hex file that is uploaded to the microcontroller IC. The code is written in type of C/C++ and when you click on the upload button, the code is compiled and converted to hex format. Now let us dig deeper and see what is happening behind the scenes. Of course you might be knowing how it works.
All the pins of micro controller IC are connected to the board which makes it easier for us to access the GPIO pins and program the IC.

Arduino boards uses a series of micro controllers that are made by a company called ATMEL. Arduino is a platform/board, which has a micro controller in it. “ Arduino is a micro controller” this statement is technically incorrect. Here I will show you how you can upload any code to any Arduino board using Arduino IDE and USB to Serial converter.
In this post I will explain everything you need to know about arduino programming, uploading and different logic levels that are involved in the program uploading. For boards like that, you will need a USB to Serial to upload code. For example Arduino pro mini and lilypad.
They are tiny compact and it can be easily programmed using a normal PC via its USB port.Īlmost all the Arduino boards like UNO, nano, MKR series can be programmed by connecting it to the USB port of a PC.īut there are some boards which cannot be program directly using USB due to the lack of USB port on the Arduino board. And it’s cool to make your own PCB for your project right?īut, the real reason why Arduino is on top of all other microcontroller boards is its ease of use. PCB helps to get rid of all messy wires and stuff and gives your project an awesome look. Making a PCB for your DIY project is not hard nowadays.
but all this things are supported by various other microcontroller boards. What make this Arduino popular among Electronics hobbyists and enthusiast? Of course they are compact with so many input and output pins, digital and analog input and output support, support for various serial communication protocol etc.
