Arduino and RGB led examples

In this article we simply show you 4 examples using an RGB LED connected  to an Arduino The RGB led we had was a common anode type, so if you only have common cathode one's available you will have to modify the code examples later on

Wemos LED matrix shield examples

In this article we will look at the wemos matrix shield, we will have numerous examples using the Arduino IDE The shield is an 8x8 LED matrix, this matrix is controlled by a TM1640.  The TM1640 is a LED (Light Emitting Diode Display) drive control circuit integrating MCU digital interface, digital latch, LED high voltage drive circuit, etc

Various Wemos RGB LED Shield examples

Here are a few code examples for the Wemos RGB LED Shield, the shield consists of 7 RGB LEDs (WS2812B-mini) each wtih 24-bit RGB color 9 optional control pins (Default: D4/GPIO2) It fits on a Wemos mini and is easy to create examples, you simply need to add the adafruit neopixel library in the library manager in the Arduino IDE Example 1 This is the default example #include <Adafruit_NeoPixel.h> #define PIN D4 #define LED_NUM 7 Adafruit_NeoPixel leds = Adafruit_NeoPixel(LED_NUM, PIN, NEO_GRB + NEO_KHZ800); void…

SHT30 and BMP180 sensor comparison

In this article we compare the BMP180 and SHT30 temperature sensors using a Wemos Mini and various shields. We will look and see if there are any significant difference in temperature readings.

micro:bit traffic light example

In this example we will create a simple traffic light system with a micro:bit. This is fairly simple and at a basic level involves switching red, amber and green LEDs on and off at certain time intervals.

microbit how to make a dice

In this article we show you how to create a dice using your micro:bit, there are a couple of ways to do this and we will also show a couple of different development examples.

5 Wemos Mini shields with examples

In this article we look at five Wemos shields and will have examples of their usage. The Wemos mini is my favourite development board for the ESP8266 microcontroller. The shields we are looking at are the PIR Shield, Ambient light Shield, WS2812B RGB Shield, SHT30 Shield and the Matrix LED Shield.

Easy Module Shield for Arduino : 7 examples

The Easy Module Shield in my opinion is one of the best shields you can buy for your Arduino Uno, the shield consists of the following features Two pushbutton switches Two LEDs One RGB LED Infrared receiving module Light dependent resistor Buzzer Potentiometer DHT11 temperature and humidity sensor module LM35 temperature sensor Here is a picture of the shield, you can clearly see the various parts mentioned above. Due to the large amount of features listed above, you can create many examples and therefore this is ideal for…

6 micro:bit LED examples using the blocks editor

In this article we will introduce you to the JavaScript Blocks Editor for the micro:bit, we will create some simple examples for the micro:bit. The blocks editor makes it incredibly easy to create simple examples with no coding, you can also switch to Javascript and see the code version of the block examples which you create.
