What is the purpose of the 4 LEDs in the circuit? 3. Describe how the two enable inputs work for this circuit. 4. Describe what the robot does when the following digital inputs are appiied to Ea, l, 12, Eb, Is, and l4 respectively.110 110 5. Describe what the robot does when the following digital inputs are applied to Ea, I, la. Es Is, and la respectively. 101 101 6. Describe what the robot does when the following digital inputs are applied to Ea, i, l2. Es ls, and la respectively. 001 010Explanation / Answer
1. Motor M1 and M2 will be connected at position mentioned at position M1 and M2.
2. 4 LEDs are connected to indicate whether lines active or not and to protect from excess current.
3. There are two Enable pins on l293d. Pin 1 and pin 9, for being able to drive the motor, the pin 1 and 9 need to be high. For driving the motor with left H-bridge you need to enable pin 1 to high. And for right H-Bridge you need to make the pin 9 to high.
4. For 110110 both M1 and M2 will rotate in Clockwise direction.
5. For 101101 Motor M1 and Motor M2 will rotate in anti-clock wise direction.
6. For inout 001010 the enable pins En1 and En2 are low so motor driver will not respond to motors and motor M1 and Motor M2 , will be at rest.
