4. Read the Button Value of IR Remote Control

5. Programming Steps

Step1：Wiring Diagram

Connect the kidsuno mainboard and computer via a USB cable, connect the IR receiver module to the No. 2 interface of the mainboard. Then connect the 270° servo to the G, V and D12 interface, the brown wire is connected to G, the red wire is connected to V and the orange wire is connected to D12, the 360° servo to the G, V and D13 interface of the mainboard(brown wire: G, red wire: V , orange wire: D13).

Step2：Add the IR Receiver

Tap the “Communication” module in the “Extension” , then select ” IR Receiver ” and click to return to the programming interface.

Diagram of the Extension Instruction Block.

Add “IR Receiver”.

Step2: Description of Building Blocks

This block is used to initiate IR receiver to the specified pin.

This block is used to receive data from the IR remote control.

This block is used to read received IR data.

This block is used to refresh the IR received data and receive the next value.

Step3：Write the Program

① Drag the instruction block in the Events module to the script area.

② Drag the instruction block in the Serial module to the script area and take the baud rate 9600 as an example.

③ Drag the instruction blockin the IR Remote module to the script area, since the IR receiver module is connected to the D6 pin of the No. 2 interface on the mainboard, then change the number 2 to 6.

④ Drag the instruction block in the Control module to the script area.

⑤ Drag the instruction block in the Control module to the script area.

⑥ Drag the instruction blockin the IR Remote module to the script area and place it into .

⑦ Drag the instruction block in the Serial module to the script area, then change “warp” to “HEX”.

⑧ Drag the instruction blockin the IR Remote module to the script area and place it into.

⑨ Drag the instruction blockin the IR Remote module to the script area.

⑩ Drag the instruction block in the Control module to the script area and change the number 1 to 0.05.

⑪ Complete Program

Step3：Test Result

Clickto upload the complete program to the kidsuno mainboard and power up, pull out the transparent sheet at the bottom of the IR remote control, then pull out the button slot, and then put in the battery(“+”pole is downward )and insert into the slot.

 Battery type：CR2025（provided by yourself）.

Then click in the serial monitor area to set the baud rate to 9600. Point the IR remote control to the IR receiver module, press a button on the IR remote control, and you will see a coded value in the serial monitor. Press the same key multiple times to make sure the value is correct. If you see “FFFFFFFF”, ignore it.

7. Programming Steps

Step1: Flow Chart

Setting	set 360° servo to 90°，270° servo rotates from 0° to180°（object raises）and OLED displays “”pattern

	Value：FF22DD	State	Crane turns left and OLED displays “←” pattern
	Value：FFC23D	State	Crane turns right and OLED displays “→” pattern
	Value：FF629D	State	Object raises and OLED displays“↑” pattern
	Value：FFA8573	State	Object lowers and OLED displays “↓” pattern
