Multifunctional Expansion Board Shield

• 7 Segment Display (4 digit)
• 2 x IC 74HC595 (driver 7 segment)
• 4 x SMT LED
• 1 x Trimpot Multiturn 10K Ohm
• 3 x Push Button
• 1 x Buzzer
• 1 x Soket Port untuk LM35/ DS18B20 temperature sensor pada U4 dan U5
• 1 x Soket Port untuk TSOP1838 infrared receiver module
• 1 x Soket Port APC220 wireless module interface (serial/UART interface)
• 1 x Tombol Reset Arduino

Jumper Pin, terdapat 2 jumper pada board, yaitu J1 dan J2.

• J1 = jika digunakan maka memberi sumber tegangan (pullup 10K Ohm) pada female header yang dihubungkan dengan LM35/ DS18B20 (termperature sensor) di Port U5-18B20-LM35-A4.

• J2 = jika digunakan maka kita dapat menggunakan Saklar S1-A1, S2-A2, S2-A3 (pada rangkaian akan terhubung dengan Port A1, A2, dan A3)

Circuit Diagram

Looking at the schematic, it looks like using the DS18B20 temperature sensor (and the infrared receiver module) requires a bit of research. As indicated in the top silkscreen layout, the flat (labeled) side of the temperature sensor must face the bottom side of the Multi-function shield fronting the three pushbuttons. Also, the legend “U5-18b20-LM35-A4” has an arrow pointing up toward the middle pin (A4) of the temperature sensor header (GND on the left, DQ in the middle, and 5 V on the right). The jumper J1 feeds 5 V to the middle pin DQ through a 10K resistor (pull-up configuration). Similarly, pin notation for the infrared receiver module is OUT (D2) – GND – 5V.
