The board uses two L293D chips. Each one hastwo H bridge that can controls two motors. FAQ Q:How many motors can be connected at most? A:4 DC motors, or 2 stepper motors and 2 servo motors. Following are options: 1. Connect 4 DC motors and 2 servos. 2. Connect 2 DC motors, 1 stepper motor and 2 servos. 3.
Connect 2 steperp motors and 2 servos. Q: Which ports are connected to DC/ Step motor? A: DC / Stepper motors are not connected to Arduino directly. They are parallel-connected to 74HC595 and then controlled by Arduino. You cannot control the motor directly. You have to use motor driver board library to drive the motor.
Q: Which ports of Arduino are used by this driver board? A: All of 6 analog ports are not used. They can also be used as digital ports?pins14-19?.They normally are used to connect sensors. Digital ports 2 and 13 are not used. The following ports are used: Digital port 11: DC motor #1 / stepper #1?PWM?
Digital port3: DC motor #2 / stepper#1?PWM? Digital port5: DC motor #3 / stepper #2?PWM? Digital port6: DC motor #4 / stepper #2?PWM? Digital port 4, 7, 8 and 12 are used when any DC motor or stepper motor is used. Following ports will be used when driving servo motor: Digital port 9: servo control #1 Digital port 10: servo motor#2 Q: How to connect unused ports?
A: Analog port (0-5 can be used as digital ports 14-19) is connected to headers at the low right corner. You can use them directly. Common Issues? Q: I ran the example codes, and ge
