WeMos® D1 mini – An Introduction
Recently, I got another packet from Banggood as usual from China warehouse. Inside the packet, there’s a WeMos® D1 mini module – this time its version 2.2.0. I’m happy to note that it’s still alive […]
Arduino Analog Sensor Reader
Hello everyone, today we’ll learn how to rig up a simple system to read and display the value of an analog sensor using Arduino and a seven-segment LED display (SSD) panel. The presented setup will […]
Arduino Power-Down & Auto-Save
Perhaps you will try tomorrow one microcontroller experiment that can store variable data in its EEPROM (electrically erasable programmable read only memory). Presented here is an idea to use inbuilt EEPROM of Arduino to save […]
Arduino OLED DVM
This article shows how to use an Arduino microcontroller (Uno/Nano) and an organic light emitting diode (OLED) display for making a basic digital voltmeter (DVM). The given design configuration makes it useful for measuring DC […]
RGB LED Module Guide
The RGB LED module shown in the above image is a very popular generic RGB LED module available in the market. There are mainly two variants of this module having common-cathode (CC) and common-anode (CA) […]
How to Build a Digital Weight Scale
Nowadays, if you want to build your own digital weight scale, it’s surprisingly easy because you only need a handful of commonly available components in addition to your favorite Arduino microcontroller board. In this primer […]
How to Play with PT100 Sensors
Recently I came across a bundle of PT100 temperature sensors (after a long time), and wanted to build a temperature sensor device with the help of an Arduino. Even though I already had a few […]
How to Play with RTC Modules
The following article is a simple guide lets you get time and calendar functions with a real time clock chip and microcontroller. Hopefully this entryway can help you to walk through your own project ideas […]
Tiny Chirp
So I have this Tiny Chirp, when you power it up, an indicator wakes up and it does a sequence of wonderful chirps! First, you need one active piezo-buzzer (i.e. the type with a built-in […]
Quick Servo Tester Nano(v3)
Here’s a nice little project of a quick servo tester with Arduino Nano (v3) microcontroller board. Another key part in this basic project is a cheap Arduino Nano(v3) expansion shield. The hardware setup is extremely […]
