Usb to serial ttl level converter

You could also use such a setup to test if the data is being transmitted properly, or if some data is being corrupted or dropped, for example if serial data between an Arduino main board and shield is being getting through correctly.

Programming an Arduino Board. This method will only work with Uno, Mega and Nano boards, as the Leonardo and Lilypad boards have the USB function built in to the main chip, so it cannot be bypassed. Note that TX on one board goes to RX on the other board- this is typical for serial communication, and can sometimes be a source of confusion.

In the example below, we've connected a Mega board. Click upload as you normally would, but while the Arduino IDE is compiling, hold down the reset button seen next to the Mega wording in the picture above , and let it go when the progress description changes to uploading this will be when the progress bar gets to near complete. If the message stays at 'Uploading…' or you get an error message, try again you might need to close the window or unplug and replug the USB-Serial Converter to reset the connection , and if that doesn't help, check the wiring.

The reason that the reset button needs to be held down is that this function is normally programmed into the USB-Serial IC on the Arduino board. There are ways of emulating this function with the XC, but extra components are required, and we'll look at this more closely with the Create a Stand-Alone Arduino below. Create a Stand-Alone Arduino.

We'll run through this as a mini project on a breadboard, but you could even lay it out on prototyping board to create your own custom Arduino compatible board. Shopping List:. The connections are much the same as with the Mega, except for the LED, capacitor and resistors.

The capacitor forms part of the automatic reset circuit which allows automatic uploading to occur. If the LED starts blinking, then all is well. Our experience shows that it is even about 10 years. Questions about the product?
