Using INA219 (GY-219) with the Raspberry Pi

Hi everyone,

I’ve just setup an INA219B Voltage/Current sensor on my RaspberryPi. Just thought I’d link the tutorials and libraries I used – there’s a lot of really useful info out there.

Install the following library via git: https://github.com/chrisb2/pi_ina219
sudo pip3 install pi-ina219

Follow this tutorial: https://www.rototron.info/raspberry-pi-ina219-tutorial/

Misc Notes

  • Common ground is required
  • Vin – and Vin+ are attached to +, neither goes to ground

Custom Sensor Address
na = INA219(SHUNT_OHMS, MAX_EXPECTED_AMPS, address=0x41)

Can be configured via the following:



Enable Low Power Between Reads
while True:
print "Voltage : %.3f V" % ina.voltage()

If you’re getting the following error:

OSError: [Errno 121] Remote I/O error

Run the following command:

i2cdetect -y 1

And check to ensure that your device is showing up on 40. If it’s a different number you’ll just need to update the address in your code e.g. (0x40, 0x41, etc.)

Mini-360 DC-DC Buck Converter – Incorrect Voltage 10v Instead of 5v

Hi everyone,

I’ve been playing around with a few DC-DC buck converters similar to these ones: https://www.amazon.com.au/UEB-Power-Converter-Module-Supply/dp/B078CXHWXC/ref=sr_1_fkmr1_1?ie=UTF8&qid=1519030369&sr=8-1-fkmr1&keywords=mini+360+buck+converter

I had expected 5v output from my 12v supply but when I hooked it up to a multimeter I found I was getting just over 10v. This would fry pretty much everything in my circuit so I was pretty worried.

After a bit of research, I came across a thread on eevblog that mentioned a screw for adjustment. Looking closely you can see that there is a small screw on the side of the chip. Turning this quarter of a rotation anti-clockwise put mine at exactly 5.04 volts.

A few other small tips:

  • The thread seems to indicate that some models require a lot more turning (up to 30 seconds for one poster).
  • I had to push down fairly hard to get it to actually turn the part underneath instead of just the metal cover

Hopefully this helps someone else out!

Duinotech Hall Effect Sensor with RaspberryPi

Hi everyone,

This is just a quick post to cover how the Duinotech hall effect sensor module (XC-4434) can be hooked up to a RaspberryPi.

Sample Code

The code below will output a zero when the sensor is activated by a magnet, otherwise a zero.

import time
import datetime
import RPi.GPIO as GPIO

# Define constants

# Setup GPIO pins
GPIO.setup(BUCKET_HALL_EFFECT_SIG_PIN, GPIO.IN, pull_up_down=GPIO.PUD_UP) # Important

while True:



When near a magnetic field the light on the sensor will turn on. If you’re using the sample code above, a zero will be shown when close to a magnet, otherwise a 1.

Could not find a version that satisfied the requirement smbus/python3-smbus

Hi everyone,

I ran into a bit of an issue installing smbus on Python3.5. It looks like all you have to do is use smbus2:

Updating to Python 3.5.1 on RaspberryPi

Hi everyone,

Just a quick post on how to update to Python 3.5.1 the normal upgrade process isn’t working for you:

cd ~
wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz
tar -zxvf Python-3.5.1.tgz
cd Python-3.5.1
./configure && make && sudo make install

You may need to restart once this is complete. Run the following to confirm that the version is 3.5.1:

pi@raspberrypi:~ $ python3 --version
Python 3.5.1

Check out the following link for more info: https://stackoverflow.com/a/37079319/522859

AttributeError: ‘dict’ object has no attribute ‘iteritems’ – Python

Hey everyone,

Just running through object detection samples for Tensorflow and I encountered the following error:

Sample: https://github.com/GoogleCloudPlatform/tensorflow-object-detection-example

AttributeError: ‘dict’ object has no attribute ‘iteritems’

The issue seems to be that the sample hasn’t been made compatible with Python 3.x. Simply make the following change and it should work:

# Original
for cls, new_image in new_images.iteritems():

# Changed
for cls, new_image in new_images.items():

Converting proto files to .py on Windows – Tensorflow

Hey everyone,

Ran into a bit of an issue today with Tensorflow:

ImportError: cannot import name preprocessor_pb2

Turned out that I hadn’t run some of the installing steps. I needed to use protoc to convert the proto directory files:

protoc object_detection/protos/preprocessor_pb2.proto --python_out=.

This turned out to be a bit of a headache as well, but thankfully a github post explained it all pretty well:

Here are the steps I followed to install it for windows:
(Prerequisite, you must have python, pip and)

Choose a Python release from here and download: Link here
– Extract the tar.gzor zip
– Open a cmd and pip install the following: pillow, lxml, jupyter, matplotlib
– Copy the protoc.exe from the protoc folder (you don’t need to do all the CMake steps you might have stumbled upon, it worked for me without them too) and paste it into your protos folder in the object detection directory.
– Run the protoc for each of those protos like “protoc object_detection/protos/*.proto –python_out=.”. . Note that you might encounter a problem with the paths and there’s two ways around that: Either move the protoc.exe two folders down or do the noobish thing that I did – copy the protos and paste them into a new directory inside the protos folder ‘object_detection\protos’ so you would have a folder structure like’\object_detection\protos\object_detection\protos’ (If it looks stupid but it works, it’s not stupid eh?) Note that *.proto might also not work and you might have to do each of them individually
– You are done. :) Try to run something to see if you have any problems. You might have to install a manual version of numpyandscipy

Compass Only Works on Pins 10 and 11 – Arduino/Software Serial

Hey everyone,

A bit of a confusing issue I ran into today. I couldn’t get my compass to work on any pins other than 10 or 11. Thankfully, there’s a fairly logical explanation:

Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 14, 15, 50, 51, 52, 53, A8 (62), A9 (63), A10 (64), A11 (65), A12 (66), A13 (67), A14 (68), A15 (69).

I ended up using pins 50 and 51 and it all worked fine. See the following links for more info:

Arduino GPS – Ublox NEO-M8N Flight Controller GPS w/Protective Shell for PIX PX4 Pixhawk

Hey everyone,

I recently purchased this GPS unit on ebay: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItemVersion&item=272492032614&view=all&tid=1865626885017

Unfortunately, I didn’t do a lot of research before getting it and had a bit of trouble finding any spec sheets or documentation. Just in case anyone else has the same problem I’ve listed out everything I needed to get it running below.

This is the wiring info you’ll need for an Arduino:
– VCC: red
– GND: black
– TXD: yellow
– RXD: white
– SCL: green
– SDA: blue

And while this post is mostly targetting Arduino, the following wiring can be used for a RaspberryPi3:
– VCC: red => pi 3.3v
– GND: black => pi gnd
– TXD: yellow => pi rx (GPIO15/Pin #10)
– RXD: white => pi tx (GPIO14/Pin #08)
– SCL: green => pi scl (GPIO3/Pin #5)
– SDA: blue => pi sda (GPIO4/Pin #7)

The default baud rate was 38400.

This is the example I ended up using to get a quick test up and running. Ensure that you map the rx and tx pins correctly (arduino tx to gps rx, arduino rx to gps tx).

This sample sketch demonstrates the normal use of a TinyGPS++ (TinyGPSPlus) object.
It requires the use of SoftwareSerial, and assumes that you have a
4800-baud serial GPS device hooked up on pins 4(rx) and 3(tx).
static const int RXPin = 11, TXPin = 10;
static const uint32_t GPSBaud = 38400;

// The TinyGPS++ object
TinyGPSPlus gps;

// The serial connection to the GPS device
SoftwareSerial ss(RXPin, TXPin);

void setup()

Serial.println(F("A simple demonstration of TinyGPS++ with an attached GPS module"));
Serial.print(F("Testing TinyGPS++ library v. ")); Serial.println(TinyGPSPlus::libraryVersion());
Serial.println(F("by Mikal Hart"));

void loop()
// This sketch displays information every time a new sentence is correctly encoded.
while (ss.available() > 0)
if (gps.encode(ss.read()))

if (millis() > 5000 && gps.charsProcessed() < 10) { Serial.println(F("No GPS detected: check wiring.")); while(true); } } void displayInfo() { Serial.print(F("Location: ")); if (gps.location.isValid()) { Serial.print(gps.location.lat(), 6); Serial.print(F(",")); Serial.print(gps.location.lng(), 6); } else { Serial.print(F("INVALID")); } Serial.print(F(" Date/Time: ")); if (gps.date.isValid()) { Serial.print(gps.date.month()); Serial.print(F("/")); Serial.print(gps.date.day()); Serial.print(F("/")); Serial.print(gps.date.year()); } else { Serial.print(F("INVALID")); } Serial.print(F(" ")); if (gps.time.isValid()) { if (gps.time.hour() < 10) Serial.print(F("0")); Serial.print(gps.time.hour()); Serial.print(F(":")); if (gps.time.minute() < 10) Serial.print(F("0")); Serial.print(gps.time.minute()); Serial.print(F(":")); if (gps.time.second() < 10) Serial.print(F("0")); Serial.print(gps.time.second()); Serial.print(F(".")); if (gps.time.centisecond() < 10) Serial.print(F("0")); Serial.print(gps.time.centisecond()); } else { Serial.print(F("INVALID")); } Serial.println(); }

Output should be something like this:

One final thing to note is that the blue light will start to flash once the GPS has a lock. You'll need a pretty open space, mine didn't work inside but got a lock within 60 seconds outside.

Let me know if you have any questions or links to better doco!
