Description
This board is designed to control two motors using the L293D chipset. It has six analog ports, which can be used to connect sensors, and two digital ports, which can be used to connect to the Arduino. Additionally, it has two H bridges that can control two motors each.
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
