Arduino Simulation Computer Keyboard


As typical input device, keyboards have special advantages when used for interactions. To give a case for example, passing push-key events to flash via keyboard spares the entire process of going through cumbersome interfaces. Although it’s easily for us to come up with the idea of disassembling the keyboard to lead out the keys. But this method has the disadvantage that the key value cannot be changed dynamically. But if only we use a simulation computer keyboard, we can set the push-key time and key value freely. This tutorial, shows how to press a key to trigger an input “HELLO WORLD” into your computer screen via the simulation computer keyboard.

1. Preparation

2. Building Process

(1) Follow the below circuit diagram to solder the resistor, USB cable and Dupont line onto the universal board.

Note: please refer to the table to find out what each color stands for.

COLOR STAND FOR
red VDD
white D-
green D+
black GND

After welding, the circuit should be like this:

It seems somewhat redundant since there are several Arduino tutorials showing how to send keyboard and mouse events from an Arduino without requiring your non-standard hardware. Your post seems to be a thinly veiled advert for that other site you linked to. Did you have a question relating to Arduino?

ya think ?
Should we click "Report to Moderator " ?

Code please.
What app is needed in the computer?

Done.

Should be moved to "Exhibitions and galleries" along with this poster's other contributions.

Another non-English speaker! Using Google translate? :astonished:

Why do I visualise them assembling PCBs using an arc welder?
