Save Water & Money With the Shower Water Monitor

Which uses more water - a bath or a shower? I was recently thinking about this question, and I realized that I don't actually know how much water is used when I shower. I know when I'm in the shower sometimes my mind wanders, thinking about a cool new projects idea or trying to decide what to have for breakfast, while water is just gushing down the drain. It would be a lot easier to reduce my water consumpt ...

Sending Data From Arduino to Python Via USB

For several projects you might want to acquire some data from an Arduino board. There are several options and the one that I chose here uses the USB connection. I will explain how to store your data in a text file in order to plot it. I will use Python 3, the Arduino IDE and an Arduino UNO. (I'm working on Linux but I think it should be the same procedure under macOS and Windows.) Step 1: The Arduino Code T ...

Using an MMA7455 accelerometer with an ESP32 board

The MMA7455L is a Digital Output (I2C/SPI), low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a low pass filter, temperature compensation, self-test, configurable to detect 0g through interrupt pins (INT1 or INT2), and pulse detect for quick motion detection. 0g offset and sensitivity are factory set and require no external devices. The 0g offset can be customer ca ...

TIME SYNC THROUGH YOUR VGA CONNECTOR

While it might be in its twilight years, the venerable VGA video connector conceals a versatile interface that  can still provide the experimenter with the opportunity for a variety of hacks. We’ve not seen anything quite like [flok]’s one, in which he uses the VGA interface to insert timing information from which an NTPd instance gets its reference. If this seems counter-intuitive because a VGA i ...

THE ARDUINO IDE FINALLY GROWS UP

While the Arduino has a very vocal fan club, there are always a few people less than thrilled with the ubiquitous ecosystem. While fans may just dismiss it as sour grapes, there are a few legitimate complaints you can fairly level at the stock setup. To address at least some of those concerns, Arduino is rolling out the Arduino Pro IDE and while it doesn’t completely address every shortcoming, it is worth a ...
