In this instructable, you'll learn how to control DC motors using the L293D H-bridge and the Micro:bit board in Tinkercad. This circuit will allow you to drive motors in both directions and at different speeds, ideal for robotics and automation projects.
Supplies
PC with internet conection and tinkercad account.
Micro:bit Board
Micro:bit Expansion Module (optional, but recommended)
L293D Integrated Circuit
Breadboard
Connection Cables
External 5V Power Supply
DC Motor
Connecting the L293D to the Breadboard

Place the L293D in the center of the breadboard, making sure each side is on separate rows.
Distribute the power connections:
Connect pin 16 of the L293D to 5V.
Connect pin 8 of the L293D to the same 5V source.
Connect pins 4 and 5 of the L293D to GND.
Connect pins 12 and 13 of the L293D to GND.
Connect the L293D to the Micro:bit

Control Ports: Connect the Micro:bit pins to the L293D control pins:
Pin 0 of the Micro:bit → Pin 2 of the L293D (Input 1)
Pin 1 of the Micro:bit → Pin 7 of the L293D (Input 2)
Connecting Power:
Connect the 3V pin of the Micro:bit to Vcc of the L293D.
Connect GND of the Micro:bit to GND of the L293D.
Connecting the Motor

Connecting the Motor
Connect the L293D outputs to the motor terminals:
Pin 3 of the L293D → Motor Wire 1
Pin 6 of the L293D → Motor Wire 2
Make sure the external 5V power supply is properly connected to the circuit.
Programming in TinkerCad

Access Tinkercad.
Create a new project.
Add blocks to turn the motor on in one direction:
Digital write Pin 0 HIGH
Digital write Pin 1 LOW
To change the motor's direction:
Digital write Pin 0 LOW
Digital write Pin 1 HIGH
To stop the motor:
Digital write Pin 0 LOW
Digital write Pin 1 LOW
Enjoy Your Setup
