The offline infrared remote control selected this time is quite practical, and Qiyingtailun also provides an SDK that is very convenient to develop and relatively powerful, which integrates the infrared code libraries of major electrical appliance brands. Infrared coding is very convenient when using it. If you are interested, you can watch the video! !
Based on the CI-C22GS02S offline voice module of Qiyingtalun, the Captain America night light doll that my son played with was transformed into a voice-controlled night light, and the infrared code can be triggered by offline voice to control air conditioners, TVs, lights, etc.
The doll is separated from the chassis before modification
Disassemble the base, measure the size, layout the component locations, and determine the component size.
Apply solder paste
After welding
Place it into the bottom case and adjust the position of the microphone and infrared receiver so that holes can be drilled in the bottom case.
Connected to the original battery and charging circuit, the battery capacity is only 280mAH, which is very convenient for daily mobile use in different rooms.
Put it into the bottom shell and fix it
The wires are too messy, so just in case, put insulating tape on the module to prevent short circuit damage to the module.
There are two wires running inside the doll for connecting the head infrared light to the chassis main control.
Welding infrared lamp
M2.8 holes are drilled in the eyes of the doll for placing infrared lights.
What the infrared light looks like after it is installed
head to body connection
Doll connected to base
Hot glue secures batteries, wires and speakers
Solder the night light and infrared light wires
The final appearance of the bottom case. After debugging, the microphone with a sensitivity of -32dB was replaced (the remaining sensitivity of the previous project was -42db, which was not good when used)
Burning wiring, when burning firmware, short-circuit the 3.3V and MCLK pins, leave 5V unconnected, select the corresponding port number, and then connect 5V to enter the burning mode. Sometimes the burning is unsuccessful due to some factors. , you can re-burn according to the above steps.
