Hello everyone,
Was trying to connect a TOF050F sensor to my Arduino in order to progress on my project for Uni.
The sensor is using a VL6180 ranging chip but every library I use, every example sketch I try to upload, it doesn't work. I get the same message every time "Failed to find sensor"
Sensor tech specs:
eBay link (sorry if I am not allowed):
Sketch used:
VL6180x sketch from Arduino example section.
Hope I can get some advice in how to get it to work.
Thank you all,
Andrei M.
Run the address finder to check you have the right I2C address.
So people don’t have to look up , a wiring diagram and the sketch is needed
Hello,
I2C address that the device was found at is 0x44 (scanned I2C 7-bit address range 0x08 to 0x77)
Sketch and pinout are attached. I connected the SCL and SDA pins only to the A4 and A5 pins on the Arduino. With the example sketch below I got no result.
SparkFun_VL6180X_demo.ino (3.8 KB)
Hope this helps.
Really need more - people like me on a phone can’t see code , you need to use code tags to show the code .
What are those other pins connected to Vin Rx etc ? Need a drawing of what you have done .
The fact you’ve found the address suggests the device is working
Have a look at the guidelines for the forum

Hello Hammy,
This is the code I used. I did not connect RX or TX since I used I2C connection. Or should I do both?
Vin is connected to +5v supply on the Arduino and GND to ground that's it.
Will this do?
