![]() ![]() You can also safely test circuits that can damage your Arduino or any other components using these simulators. This can be great for testing purposes to confirm that a given circuit works before you go out and buy all of the required components for the same. In other words, you can easily create any circuit or Arduino project right on your computer. You can then even add all kinds of virtual connections, components, devices, and much more. Readers can extend more complex, more interesting USB tools for interaction with PS from gaining a little bit inspiration from this simple enough USBkey.An Arduino simulator for PC will allow you to run a virtualArduino on your computer to put it in simple words. So far, the building of Arduino simulaltion keyboards comes to the end. Press the number keys on the UNO, the word “HELLO WORLD” will appear in the text, as shown below: (5) After downloading the code, unplug the UNO code to download USB, plug in this simulation USB keyboard and then open a text on the PC end. You need to note that for a successful compilation of USBKEY, it’s necessary to put UsbKeyboard files into the folder “Arduino IDE libraries” in advance. (3) connect the number key to D1 pin on UNO If readers need to use other pins, it can be achieved by modifying the wiring definition of the USB pin in usbconfig.h in UsbKeyboard library. NOTE: the wiring method in the second step is not fixed. (2) Connect the Dupont line welded as the upper picture displays to UNO by referring to the table. ![]() Note: please refer to the table to find out what each color stands for.Īfter welding, the circuit should be like this: (1) Follow the below circuit diagram to solder the resistor, USB cable and Dupont line onto the universal board USB cable 100 ohm resistor 2.2k resistor Number keypad Freaduino UNO Dupont Line 2.2k universal board ![]() This tutorial, shows how to press a key to trigger an input “HELLO WORLD” into your computer screen via the simulation computer keyboard. But if only we use a simulation computer keyboard, we can set the push-key time and key value freely. But this method has the disadvantage that the key value cannot be changed dynamically. Although it’s easily for us to come up with the idea of disassembling the keyboard to lead out the keys. To give a case for example, passing push-key events to flash via keyboard spares the entire process of going through cumbersome interfaces. As typical input device, keyboards have special advantages when used for interactions. ![]()
