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 Interfaced to NodeMCU
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 […]
ESP8266 ESP-12E Arduino Clock W/ Outside Temp & LEGOS & NeoPixel Ring
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 […]
Arduino Chicken Coop Controller
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 […]
Debounce an input using Arduino
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 […]
Arduino Calculator
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 […]
ESP8266 Basement Monitor
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 […]
DIY AM Radio With Arduino
After I finished my last project, I couldn’t stop thinking how to build an AM receiver, that would also operate in conjunction with my little friend Arduino. To minimize a workload and complexity, especially with RF part of the circuitry, I come up to conclusion, that SDR (Software Defined Radio) is the best choice for […]
Blink Without Delay using Arduino
Sometimes you need to do two things at once. For example you might want to blink an LED (or some other time-sensitive function) while reading a button press or other input. In this case, you can’t use delay(), or you’d stop everything else the program while the LED blinked. The program might miss the button press […]
Controlling Devices in Swift With BLE
In this project we will use an iPhone to control devices connected to an STM32 device. The project is a starting point for more exciting experiments such as remote controlled robots or any other thing you might want to control in your home. I encourage you to check out the source code which is really […]
