7. How it works:
Switch power to "ON". The LED 1 will light up and the unit will emit 3 beeps as it starts running.
When the unit starts running, the emitting diodes LED2, LED3 and LED4 will send out signals
sequentially to detect obstacles along its path.
Once an obstacle has been detected, the signal received will be transmitted to the receiving module
which will then instruct the Escape Robot to take evasive actions.
aWhen the emitting diode on the right detects an obstacle, the unit will emit a "beep" sound, and
the left motor will go into reverse mode.
bWhen the emitting diode on the left detects an obstacle, the unit will emit a "beep" sound and the
right motor will go into reverse mode.
cWhen the emitting diode in the middle detects an obstacle, the unit will emit two "beeps" followed
by the two motors going into reverse mode. Then, the operation of (a) above is repeated.
dIf all three emitting diodes detects obstacles, the unit will emit three "beeps" and the movement
that follows will be the same as in ( c ) above. However, the turning will take a little longer.

8. Trouble shooting:
Ensure that all components on the PCB are in order. Take note especially of the
polarity of the infrared emitting diode.
Different environment and battery power may affect the detecting sensitivity,
try to adjust the Infrared Receiving Module's angle to find the best position.
