@@BaldGuyDIY Hello there again, thanks for your attention , I am trying to build my non-contact thermometer with a MLX 90614 sensor and an Arduino UNO , I also have an Arduino NANO if better or easier, the display I have is a 7 segment 0.56" LED HT16K33 Adafruit Backpack
kevin cazana it isn’t going to matter which one of your Arduino microcontrollers you use, it’ll be the same. Those are both I2C devices, so both of them will connect to 5V, GND, SDA and SCL. One Arduino can communicate with multiple I2C devices, they just need different addresses. The sensor address is fixed and can’t be changed, but the backpack can be changed. The Adafruit guide for the sensor setup is learn.adafruit.com/using-melexis-mlx90614-non-contact-sensors/wiring-and-test?gclid=CjwKCAjwkdL6BRAREiwA-kiczGy8K1Ny7bnpNCUKlNKBBaYCVowzXAgfcKdRAlo5OXFaZ2v8iX2uPBoC5b0QAvD_BwE and the backpack is learn.adafruit.com/adafruit-led-backpack/1-2-inch-7-segment-backpack-arduino-wiring-and-setup?gclid=CjwKCAjwkdL6BRAREiwA-kiczC9FNxLGVazpOCLSve7RjGfDlYJ6MXFzyzNZrU3V7MYDdrF8Tvy0tBoCVIIQAvD_BwE I’d recommend trying each device on its own at first and make sure you know how to communicate with them, then put them on the same I2C connection and see if they still work together. If they don’t, change the address on the LED backpack and try again. Good luck!
Can you PLEASE show me how to make the Adafruit 1.2" inch 4-digit 7-segment display show a DECIMAL point. I followed your video here but it seams to only work with the smaller 7x4 display. Thanks
Captain Bucks Adventure Time if you load the same script I used in the video, there’s an example of a decimal being used. Does that sample script display the decimal?
I have used the code supplied in the example 7 Segment, but NO it does not show a decimal. What I really need is a 1-2 inch LED 4 Digit 7 Segment Display that will allow a floating decimal for a Speed Trap display for a Slot car system I am trying to design ! And help will be rewarded !
I would suspect there’s a problem with the connections to the backpack or with the backpack itself. Double check all your solder points. If it displays everything but the decimal point that sounds like a possibility. Also try putting the decimal in different places in the sample script. 1.234, 12.34, 123.4 and see if any of them work.
Thanks very much. BTW, I am using JetBrains CLion with C language
Hello there BaldGuy, could you show me how to connect the backpack to arduino uno for non contact thermometer?
Can you send me the part numbers of your components such as the thermometer and backpack, and I will take a look!

Captain Bucks Adventure Time hello! Do you have the i2c backpack on the 1.2” display?
@@BaldGuyDIY YES . For some reason I can not get it to display a Float value ! Or the upper right decimal

Hi there BG , where can I order the backpack from? Thanks
Thanks for checking out the video! www.adafruit.com is where you can get both the 7 segment displays and the i2c backpack.
can you send me the code? they updated the github page :( big sad
More speciically, I need the code in 5:44
Hi Paul, I can send the code if you email me your email address. brandon@baldguydiy.com. Thanks for watching!
@@BaldGuyDIY Hi BaldGuyDIY, I am interested on the code too. I sent you an email already.
