This paper incorporates the LSB (Least Significant Bit) steganography for a text in color images in the\nRGB (Red Green Blue) format. A certain pseudorandom seed (key) is utilized in both sender and receiver sides, for\nrandomly embedding and retrieving the text bits. The Arduino microcontroller is used to manage all the operations\nneeded, with SDRAM shield to store the image and an LCD display to show required messages and control options.\nThe embedding and retrieving principle used may apply to almost any host image size because it were accomplished\non each randomly chosen pixel and does not require loading the image to the Arduino kit. The host image showed\nquite good PSNR as compared to the original, the PSNR was 75.5% for a 10 bytes embedded text, and gets lower as\nthe text bytes increase to be 55.14% for 100 bytes of embedded text. An image of dimensions of 256x256 is used as a\nhost image. The method is simple, versatile, and efficient.
