This sketch uses the Serial.parseInt() function to locate values separated by a non-alphanumeric character. Often people use a comma to indicate different pieces of information (this format is commonly referred to as comma-separated-values), but other characters like a space or a period will work too. The values are parsed into ints and used to determine the color […]
Lighthouses have been guiding boats to safety for thousands of years. One of the earliest and most notable of these was the Pharos of Alexandria. This huge structure stood for nearly two thousand years. When deciding on a lego project, I wanted to build something practical, yet at the same time fun. Although I won’t […]
Hi makers! This is my first instructables and I want to address some important things firts: I made this project with the idea of using the lest amount of tools so that everyone could do it! Even I don’t have lot’s of tools, only the strict necessary I’m not an electrical engineer or a coder, […]
Wassup Makers!! In this Instructables we will learn how to interface an LCD (Liquid Crystal Display) to the NodeMCU board. These 16×2 LCDs are very popular and broadly used in electronics projects as they are good for displaying information like sensor data from your project, and also they are very cheap. Step 1: Things Needed We need few components to get […]
OLED!! What is an OLED? OLED ( Organic Light Emitting Diodes ) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting. Because OLEDs emit light they do not require a backlight and […]
We went all ‘cord-cutter’ and ditched our Cable box and realized something was now missing in our family room…the oh so familiar LCD clock that was always present. I decided to get to work on a replacement and had some fun with it. If you’re like me you’ve ordered an Arduino kit here and there when the […]
Over the last few years my family has been keeping ex-battery hens – they are about 18 months old and have had a horrendous life kept cooped up in small cages in large warehouses. As much as we love these little bundles of joys and eggs it can be a drudge getting up in the […]
This example demonstrates how to debounce an input, which means checking twice in a short period of time to make sure it’s definitely pressed. Without debouncing, pressing the button once can appear to the code as multiple presses. Makes use of the millis() function to keep track of the time when the button is pressed. Circuit image […]
In this Instructable I will show you how to make an Arduino calculator that is just as good as any other calculator (well… sort of). Even though it’s probably not practical due to it’s size, repetitive use of the equals button (due to the lack of keys), and cost (You can probably buy a calculator […]
My basement gets wet when it rains a lot so I wanted a way to monitor it. I decided to try using an ESP8266 as it has built in WiFi. I paired that with a DHT22 Humidity & Temperature Sensor and a float sensor to monitor my sump pump. Using the ESP8266 is easy enough […]
