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 -
In this article we will look at the wemos matrix shield, we will have numerous examples using the Arduino IDE
The shield is an 8×8 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 -
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.
