    You can study English by doing programming for free. Register in the website and get tasks to solve from a teacher of the website. Discuss programming in Chats with a teacher and other members for free. You don't need any prerequisites. No matter if you are going to be a programmer or not, programming is a good exercise for your brain. Do you need to calculate your taxes every month? Do you need to calculate percents of your mortgage? Do you need to calculate how much gasoline you need for your car during a long trip? Do you want to make a personal interval training with a clock and beeps for exercises and rests? Do automatization and let a computer calculates all routine work. We will teach you the most popular programming languages C++, JavaScript. We will give you basic knowledge of algorithms and the main principles useful for any programming language. Dive into English and Programming with Easy English Study website and enjoy the learning process in informal settings.

    Open esp32simulator. Create the folder "blinky" in the directory "esp32projects". Create "main.py", "diagram.json" inside the folder "blinky". Connect all components with wires in the same way, as in the picture. You can rotate a component by pressing Ctrl+R. The resistor must be connect to D15. Pay attention to LED, since it emits light only if it's connected correctly. The current must go from an anode to a cathode (LED will not emit light if you connect it in the opposite direction). [image: 1743493140012-blinky.png] Paste the next code to main.py. from machine import Pin from utime import sleep led = Pin(15, Pin.OUT) #makes Pin 15 an output while True: led.on() #turns on LED sleep(2) #time delay 2 seconds led.off() #turns off LED sleep(2) Click the green button to run the project. You should see a blinking LED. Save your project to the local folder "blinky". Copy-paste the code from the files "main.py", "diagram.json" in the simulator to your local files. Make a screenshot of the circuit and save the screenshot to the folder "blinky". Whenever you want to continue programming you can copy-paste the code from the local files to your simulator (Note. The circuit is stored in the file "diagram.json", you don't need to make a new circuit all the time).

    You can make a real circuit and use blinking LED for a Christmas tree or put it in a toy police car and give it as a gift to children.
