What does the pharase “clearCharacters” mean? When compiled, it says clearCharacters was not declared in this scope.

Hello sir. Thank you for the great video. I have a question about the emissivity of MLX90614 because I was trying to measure human skin temperature but the emissivity of human skin is not 1 (approx. 0.98 - 0.95) since the default value of the sensor emissivity is 1. Is there any tutorial on changing the emissivity of the sensor?

a simple google search showed this which tells you how to set emissivity github.com/sparkfun/IR_Thermometer_Evaluation_Board-MLX90614/blob/master/Libraries/Arduino/examples/MLX90614_Set_Emissivity/MLX90614_Set_Emissivity.ino

@@robojax I have tested using all kinds of libraries (from google) . The library that you shared didn't work for me (tried it for few days) . In the end, my only hope is to use i2c library to communicate with the sensor which indeed work out but the final coding was longer. Thank you for the reply.

Hello, at 8:10 (click on 8:10) I have explained if you want to do something with the temperature. that something can be buzzer or relay or motor. I have over 400 videos with full explanation with them. here is example of controlling a relay kzitem.info/news/bejne/lm6OvYp6p3Rohqg or you can control a buzzer instead of relay. Make sure to watch the MLX9061 main video so you learn how it functions kzitem.info/news/bejne/y4RunISJenp-law . this video with LCD was just how to use it with LCD not explanation.

because you have not watched the introduction video to LCD. the link is in the description and I have mentioned in the video. This video combines MLX90614 and LCD. So I did not talk about the MLX90614, you have to watch that video to learn about the infrared sensor and watch introduction to LCD to learn about them. This video is just showing you how to put them together. Check the links, watch and the issue will be resolved.

Provide error. saying there is error is not enough. by the way if you skipped the introduction to MLX90614 video and you skipped to introduction to LCD video, then definitely you should get error. This is combining codes from two other codes and you need to watch this videos.
