There is no shame in asking for help when you get stuck on your Arduino projects, but there are definitely right and wrong ways to ask for help. Often people are not sure what information needs to be displayed. Here are some simple tips on how to ask a question, and how to trouble shoot to be able to get the information needed for a question
Read MoreThis project is to give a practical example of using power save modes with Arduino's. It uses a Real Time Clock (RTC) to wake up an Arduino Data Logger. It write the temperature and humidity in a room to a micro SD card. It is optimized for saving power thus can run of a battery pack.
Read MoreIf you need to run your Arduino of a battery pack, you need to find a way to reduce it's power consumption. One of the the best ways to do this is putting your Arduino to sleep when it is not performing any tasks. This tutorial is a great place to start on learning how to put your Arduino to sleep.
Read MoreA lot of makers don't know how important it is to know the current draw of your project, or why you need to know this. In this tutorial I will explain to you how to measure the current draw of your project, and why it is so important to know this.
I often get asked the question of what type of power supply to use for projects. Most of us know the voltage required, but how much current it draws and why you need to know this is a mystery to many beginner makers. To start with what is this current thing? "In comes the analogy that uses the flow of water to explain these things".
Read MoreThese 5 tips can help you write better, and more functional code for your Arduino projects. These helpful tips help you understand how important it is to use descriptive variable names, indent your code, use comments, the use of functions to make your code more reusable, and write documentation for your projects.
These 5 tips are useful for both novice makers/developers and more advanced ones. They are often overlooked making an otherwise great project a nightmare to deal with
Read MoreThis is Part 2 of a 2 part tutorial that will simplify the way you can store your WiFi configuration on an ESP8266 using the EEPROM library. With this knowledge you can then build Internet Of Things (IOT) projects that can be configured by web form. This will enable to change passwords or IP configuration when needed without having to recompile your sketch.
In part 2 you will learn howto read information "your stored in memory in part one" out of memory. How to use it to configure your IOT device to connect to your WiFi network, and make it user configurable by combining Part 1 and 2 in one sketch
Read MoreThis tutorial is part 1 of 2 that will simplify the way you can store your WiFi configuration on an ESP8266 using the EEPROM library. With this knowledge you can then build Internet Of Things (IOT) projects that can be configured by web form. This will enable to change passwords or IP configuration when needed without having to recompile your sketch.
In part 1 we learn how to write the information to your IOT project, part 2 will teach you how to read this information out of memory and configure your IOT project so it can connect to your WiFi router
Read MoreWith Halloween coming around the corner it is time to see how we can automate some scary projects. We are going to explore two of my favourite ways to do this. First we are going to look how to integrate a pressure plate switch (a big push button you step on which we are going to build), then we will look at how to connect a motion sensor (Passive Infrared Sensor or PIR) to your scaretastick project for the maximum scare factor. I recommend you also watch the video below to get the most out of this tutorial.
