Then you will define the pin in which you want to connect the push button. You will include the keyboard library to emulate a keyboard. The software that you'll need to upload the script to the board is called Arduino IDE, you can download it here. In the first step you are going to create a simple action to “copy” when you press a push button. The first thing to consider: as you will be emulating keyboard inputs, you should be careful not to leave a free keyboard action in the loop repeating and repeating itself, because you will lose control of the computer. The code The software that you'll need to upload the script to the board is called Arduino IDE, you can download it here. In the setup, you will define the variables and modes that will be needed in the project the loop is the set of instructions that Arduino will be running over and over to check the status of its different inputs and outputs. In the first step you are going to create a simple action to copy when you press a push button. If this is your first Arduino project, you should know that the basic structure of an Arduino script consists of two parts: the setup and the loop. It will be easier if you already have experience with coding, but I encourage you to learn by trial and error if this is your first approach.
#Arduino push button to start program how to#
This tutorial will, not only guide you through the project, but it will also introduce you to Arduino in general, starting with a very simple push button as keyboard input and will teach you how to add buttons and features in the next steps. 1 Resistor (this one is optional, any between 110 to 330 ohm will do).

1 Arduino Leonardo (or any Arduino with usb interface).

In my case, I use it with coding software to have an easy and fun shortcut to copy, paste, duplicate line, save, capture screen and open a couple of apps. You will create a panel with different buttons, each one will do an action in your computer (Mac or Pc) by emulating keyboard shortcuts or commands. This is a pretty simple and fun project with Arduino which is an ideal option for your first interaction with Arduino.
