Hello! Do not stone, this is my first publication.
The other day did homemade from an old non-working toy and binding to a Blynk server. The result was a tank with control from a smartphone from anywhere in the world.
What we need:
1. an old toy with two motors, or printed on a 3D printer
2. nodemcu V3 board
3. driver for L293D motors
4. breadboard
5. wires mom dad dad dad
6.Cron battery
Step 1.
We connect the motors to the driver.
Step 2
We connect the battery to the driver and the Nodemcu board. I ordered two crowns with Ali charging from usb.
Step 3
Write a sketch in the IDE. A good feature of the Blynk server is that almost nothing needs to be written in the sketch! All the bindings we will produce in the application.
Step 4
And finally, we create 4 buttons to control the tank:
- right engine forward
- right motor back
- left motor forward
- left motor back.
In order not to burn the motors, I advise you first to put the LEDs in their place and watch on them whether the application works or not.
