Introduction In the previous tutorial I showed you how to build a weather station using only the DHT11 sensor and I said the readings from this sensor is fairly accurate. In this tutorial, I will be using the DHT11 to measure only the humidity and BMP180 to measure pressure and temperature. That’s because its readings are more accurate than the DHT11 temperature readings. Project Parts I will be adding only ...

This tutorial was done on Windows. Authors claim it could also be used on Linux by using Mono, but I haven't tried and don't understand a lot about Mono to see what could be done. I am switching to Linux nowadays, so I'd be very grateful to anybody that'd make instructions on how to launch it, however - and I'm sure other fellow Linux-wielding engineers will be grateful, too =) This is the GitHub issue desc ...

A PC application that talks to the Walabot PRO, Arduino and NeoPixels! Story Welcome to my Walabot project I will split this project in different parts 1. Get to know the Walabot and a setup. This includes data readout and send it to an Arduino. 2. Gather the data that is needed for the calculations and create an image with this data 3. Convert the data to an object Getting started with the Walabot I've mad ...

Every day the Arduino Team will select some of the best tutorials and highlight them on our ...

The ESP8266 has become one of those ubiquitous parts that everyone knows. However, the new ESP32 has a lot of great new features, too. If you want to take the ESP32 for a spin, you should check out [Neil Kolban’s] video series about the device. When we say series, we aren’t kidding. At last count, there were nineteen videos. Some are only a few minutes long, but some weigh in at nearly twenty minutes and th ...

Do you (still) remember the display of your old CD player, HiFi system or car radio? Have you ever noticed the displays used at your local supermarket that shows you the scanned item and the price of it? These displays have a characteristic beautiful bright blue-green colored glow in common: These are so called vacuum fluorescent displays (VFDs) with outstanding brightness that look pin sharp. Used to repla ...

Okay, here's the deal. There are some tutorials on youtube showing how to get graphics to show on the nokia 5110 and that's great. If you just want a simple way to do that, go and watch them instead but there are a few problems I see, 1. There are none for mac. I am using a mac and everyone in the videos are using a windows. 2. Sometimes I just wanna go to the computer and search up how to make some graphic ...

If you want to learn more about the ESP8266 module, first read my Getting Started Guide for the ESP8266 WiFi Module. In this project you’ll create a standalone web server with an ESP8266 that can toggle two LEDs. Why flashing your ESP8266 module with NodeMCU? NodeMCU is a firmware that allows you to program the ESP8266 modules with LUA script. And you’ll find it very similar to the way you program your Ardu ...

Quickly testing a GPIO pin To set pin GPIO_PH1 as an output: sudo su (Enter your user password. Defaults to "ubuntu") # See which pins are currently configured as GPIO, and what their state is. cat /sys/kernel/debug/gpio # Validate that the entry for the Tegra GPIO controller has a base value of 0. If not, add on whatever the base value is to the “57” in the commands below. echo 57 > /sys/class/gpio/expo ...
