Discover how to make an infrared sensor CNY70 support compatible with LEGO (bricks) pieces to be able to insert it in your robot.
A housing has been designed with OpenScad for CNY70 infrared sensor compatible with LEGO (bricks) pieces:
Download the STL file and print it.
(Suggested) printing parameters:
Height of layer (mm): 0.3
The parecedes thickness (mm): 0.8
Upper and bottom part thickness (mm): 4.2 (very important, but break the top cylinders)
(Mm/s) printing speed: 30
Without platform accession
All the components shown below in an image.
As we can see in the picture, from left to right we will need:
- A 220Ω resistance.
- A 47KΩ resistance.
- Two wires of different colors.
- Heat-shrink plastic.
- Sensor CNY70
- Three-pin male connector.
- Printed top of bracket.
- Print in 3D.
The first step would be to place the heat-shrink plastic and solder wires and resistance to the CNY70 according to the connection diagram shown below.
You should obtain something like this:
Secondly, we put the cables through the hole in the sensor CNY70 and lift them up with the help a pliers or a screwdriver, then solder the three pin connector, as shown in the following image.
After entering three-pin connector into the slot already you have finished the sensor housing. On the top of the sensor, we have also designed a cover, as shown in the resulting images.
