Optical Flow Sensor
Optic Flow Module:
The optic flow module understands the drone’s movement via processing the images of the ground. In this way, drone can stay in the same location or it can move autonomously.
Optical Flow Module Connection:
Note: Module direction is important. It should be connected as the picture.
Optic Flow Blocks:
1-) Get altitude:
This block will return drone ESPcopter altitude data that come from the altitude sensor which is vl53l0x. The range of the sensor data is 0 - 1200mm.
2-) Get Optical Motion X:
This block will return drone ESPcopter optical flow sensor motion data on the x-axis.
3-) Get Optical Motion Y:
This block will return drone ESPcopter optical flow sensor motion data on the x-axis.
Neopixle
Neopixel Block:
Neopixel block is working by using RGB color format. RGB(RED GREEN BLUE) color format refers to a system for representing the colors. Red, green, and blue can be combined in various proportions to obtain any color in the visible spectrum.
There are four inputs in the Neopixel Block these are Led No, RED, GREEN, and BLUE.

- Turn Off 0.Led:
2- ) Setting brightness of LEDs
- Turn On 8. Led as a %20 RED:
- Turn On 8. Led as a %20 White:
3-) Changing color any of Whole Led:
- Change the color of whole LEDs:
- Change the color of whole LEDs by one by:
- Change the color of whole LEDs by one by. And then, turn off by one by:
- Change the color of whole LEDs to RED with %20 by one by. And then, turn off by one by. Make it continuously:
- Change the color of whole LEDs to RED by one by. And then, change the color of the whole LEDs to Green by one by. Change the color of the whole LEDs to Blue by one by. Make it continuously:
