C-9812
Finished Product
How it works
1 - Switch power to "ON".
2 - Put Ladybug Robot on the ground and see if it goes forward
smoothly.
3 - When unit detects obstacle it will turn left. Remove the
obstacle, it will go forward continuously.
4 - Adjusting the "variable resistor" to change the
detecting distance.
Trouble shooting
1 - Ensure that all components on the PCB are in order. Take note especially of the polarity of the infrared emitting diode and the
photo transistor.
2 - Ensure all wiring is correct.
3 - The range of detection of the unit may be affected by low battery status. Adjusting the variable resistor to improve the range.
