Great Job! I’m set up with the distance and temp/humidity sensor to my Uno, but my LCD has the I2C converter on it. Any chance you or somebody could help me out with getting to distance displayed on my I2C LCD display? I know how to connect my display to the Uno, just not sure if anything needs to be changed in the sketch to work with my display properly. I hope that all makes sense.

i made the exact same circuit (A GREAT SOUNDING LM386 AUDIO AMPLIFIER). I tested it and it worked! After doing so i decided to make the other channel (stereo sound), and replicated the circuit on the other side of the board. The power supply is a 12V, laptop supply. Such PS is feeding both circuits in parallel.

However, neither of both circuits are working anymore (the circuit no. 1 worked before and circuit no. 2 never worked).

What am I missing?

The i2c backpack has a variable resistor this adjusts the contrast. Write a program which displays a string on line one and immediately exits. Now with a small screw driver adjust that potentiometer. Hopefully the string is now on display.

I’m having a problem in getting the C program to run (on terminal). It only shows “Data not good, skip” and I never get a valid reading.
The only change I did was to use GPIO pin 25 instead of 7 (I tried several GPIO pins including 7)
#define DHTPIN 25

I tested the Python version and it runs without any issues with the same wiring. In this case I entered BCM pin number 26 which corresponds to wiringPi pin 25.

So I guess my jumper cable wiring is correct and my GPIOs are still functional.

Any ideas on how to debug this?

The error is on the “lcd” line.

It should be like this (copied from the article above):
lcd = CharLCD(cols=16, rows=2, pin_rs=37, pin_e=35, pins_data=[33, 31, 29, 23])

You are missing the equal sign (=) after pins_data, and this creates a function call that is invalid in Python (if you are curious why, look up “keyword arguments”, and you will see that all non-keyword arguments must occur _before_ any keyword argument).

It really is as simple as that 🙂

For example, if you’re using Python, you can read three DHT11 sensors on GPIO 4, 5, and 6 like this:

humidity1, temperature1 = Adafruit_DHT.read_retry(11, 4)
humidity2, temperature2 = Adafruit_DHT.read_retry(11, 5)
humidity3, temperature3 = Adafruit_DHT.read_retry(11, 6)
