Random flashing MAX7219 example
Another MAX7219 example using random numbers to randomly light an LED in the matrix, you may want to increase the delay Code #include “LedControl.h” // need the library LedControl lc=LedControl(12,11,10,1);…

The first thing you will need that makes things easier is to download and install the LedControl Arduino library as it is essential for using the MAX7219. Code #include…
Similar to the previous single colour LED example this is for an RGB led, we use pin 6, 7 and 8 Code //simple button GET server code to control…
This requires an ethernet shield and an LED connected to pin 6. Copy the code into a new sketch and upload it to your arduino and then open your web…
While browsing through the mikroelectronika website and looking at available downloads, I noticed their Basic compilers for various microcontroller architectures. So after downloading the 8051 version and installing lets look…
Its fairly straightforward to connect a 7 segment display to your 8051 processor, in this example we will do this and show a code example which cycles through the numbers…
In this example we connect an RGB LED to our 8051. In this case we used an RGB LED breakout, this was a common anode device. The schematic below shows…
Recently I purchased several 8051 type development boards from China, most of the examples were written in Keil. As a test I decided to see if i could get any…
A very simple example that toggles a set of 8 LEDs based on whether a switch is pressed or not The switch is connected to Port 3.0, the LEDs are…
This is a hexadecimal counter using LEDs. It will start at 0xFF and count down 1 Code #include <reg52.h> void delay(unsigned int i); main() { unsigned char Num =…
