A total of two data will be sent and received for the two axes. Two variables are defined to read data from the joystick X and Y axes. On the transmitter side, the pins to which the Joystick X and Y axes are connected are defined. Two 3.7V 18650 Li-ion batteries were used for power.
You can connect the breadboard circuit according to the circuit diagram shared above. Therefore, two L293D ICs were used in the project, which also enables the use of two stepper motors. Two DC motors can be controlled with one L293D IC motor driver, but the current supplied may be insufficient for more powerful DC motors. However, the amount of current supplied to the motor depends on system’s power supply. You can connect two DC motors having voltages between 4.5 to 36V to these terminals.Įach channel on the IC can deliver up to 600mA to the DC motor. The L293D motor driver’s output channels for the motor A and B are brought out to pins OUT1, OUT2 and OUT3, OUT4 respectively. And they both sink to a common ground named GND Vcc1 is used for driving the internal logic circuitry which should be 5Vįrom Vcc2 pin the H-Bridge gets its power for driving the motors which can be 4.5V to 36V.
The L293D motor driver IC actually has two power input pins viz. That means it can individually drive up to two motors making it ideal for building two-wheel robot platforms. The L293D is a dual-channel H-Bridge motor driver capable of driving a pair of DC motors or one stepper motor. It can control both speed and spinning direction of two DC motors.Īlso, it can even control a unipolar stepper motor like 28BYJ-48 or Bipolar stepper motor like NEMA 17. To briefly mention the L293D motor driver, one of the easiest and inexpensive way to control DC motors is to interface L293D Motor Driver IC with Arduino. L293D IC motor drivers were used on the receiver side of the project.
