Create an Inventory file first

sudo mkdir /etc/ansible

Edit Ansible hosts or inventory file

sudo vi /etc/ansible/hosts
Add the below two lines in the end of the file:
[localhost]
local

cd ~
mkdir playbooks  

cd playbooks

Create Ansible playbook

sudo vi create_ec2.yml 

(copy the below content in green color)

edit the create_jenkins_ec2.yml to make sure you update the key which is red marked below:

       local_action: 

         module: ec2_group

         name: "{{ security_group }}"

         description: Security Group for webserver Servers

         region: "{{ region }}"

         rules:

       register: basic_firewall

     - name: Task # 2 Launch the new EC2 Instance

       local_action:  ec2 

                      group={{ security_group }} 

                      instance_type={{ instance_type}} 

                      image={{ image }} 

                      wait=true 

                      region={{ region }} 

                      keypair={{ keypair }}

                      count={{count}}

       register: ec2

     - name: Task # 3 Add Tagging to EC2 instance

       local_action: ec2_tag resource={{ item.id }} region={{ region }} state=present

       with_items: "{{ ec2.instances }}"

       args:

         tags:

           Name: MyTargetEc2Instance

now execute the ansible playbook by
ansible-playbook create_ec2.yml

If everything is good, you should see the new instance created on AWS console. make sure you are able to connect to that instance.

That's it!! That is how you create a new EC2 instance using Ansible.
