WEEK 12 (23.10.2017 – 27.10.2017)

For this week, after we had finish with the coding we solder the circuit for the proximity sensor circuit and trouble shooting the circuit. This is the connection of the proximity part.

Connections:

HC-SR04 Sensor

- The HC-SR04 Ultrasonic Module has 4 pins, Ground, VCC, Trig and Echo. The Ground and the VCC pins of the module needs to be connected to the Ground and the 5 volts pins on the Arduino Board respectively and the trig and echo pins to any Digital I/O pin on the Arduino Board.
- The HC-SR04 sensor attach to the Breadboard
- The Sensor VCC connect to the Arduino Board +5V
- The Sensor GND connect to the Arduino Board GND
- The Sensor Trig connect to the Arduino Board Digital I/O 9
- The Sensor Echo connect to the Arduino Board Digital I/O 10

Buzzer and LED

- The Buzzer attach to the Breadboard
- The Buzzer long leg (+) connect to the Arduino Board Digital 11
- The Buzzer short leg (-) connect to the Arduino Board GND
- The LED attach to the Breadboard
- The Resistor connect to the LED long leg (+)
- The Resistor other leg (from LED's long leg) connect to the Arduino Board Digital 13
- The LED short leg (-) connect to the Arduino Board GND
