• IR_TX: when D3 is set as high level switch, IR Diode will emit signals out. When D3 is set as low level switch, IR Diode won’t work.
• IR_RX: Use HS0038B as IR receiving module
• Jumpers:

Jumpers can directly connect to Arduino’s IO. If you don’t need them or their corresponding pins are occupied, you can remove the jumpers.

• A0: insert a 10K resistance to A0 button
• LED1: connect to D6 pin. If the output voltage is high, LED1 turns on.
• LED2: connect to D7 pin. If the output voltage is high, LED1 turns on.

• Switch: Set the switch level according to Arduino main board. When the mainboard is set in 5V, you should turn the switch to 5V; when in 3.3V, you should turn to 3.3V.
