Hello world! Today i wanted to test a new sensor for my collection and i attached a 1602A LCD to it using a I2C on the LCD. You can easily change it in the code when you want to use normal wiring by uncommenting and commenting some lines. There are 2 codes 1 For fahrenheit & 1 for Celsius. Follow the next step for the Schematic Code & Parts list.
You can simply change the code to normal wiring if you do not want to use the I2C, I put the lines in the code already. I attached to codes for Celsius & Fahrenheit, but you can also edit those by uncommenting some lines & by commenting others. Just read the code, it's all there.
Step 1: Schematic, Code & Parts List.
Simply wire everything up like the schematic, solder your sensor to a Prototype Board or use a breadboard.
I also added a scanner to find out your I2C address.
- Arduino uno, I used the RobotDyn uno. (Has 8 analog pins)
- NTC Thermistor Waterproof.
- Jumper wires MM/FF/MF set
- LCD 1602A
- PerfBoard/Prototype Board or Breadboard.
