the loop routine runs ensuring the program cycles from beginning to end ad infinitum. Published on: 21 October 2021 Its impossible not to love Helen Nicoll and Jan Piekowskis accident-prone witch Meg and her best friends, Mog and Owl. We recommend starting with the original classic Meg and Mog where Meg and her cat go to a wild Halloween party, with unexpected results. Meg is getting ready for her Halloween tea when disaster strikes and her teapot breaks Meg uses her spells to magic a. initialise the digital pin as an output. the setup routine runs only once, and each time you press reset. I fastened the control board and battery pack to a small piece of wood and put into a plastic bag to waterproof. Using 4 x AA batteries is a better option than using a single 9v battery as it is more efficient and has more capacity as well as being cheaper. I powered the board and LEDs with a 4 x AA battery pack plugged into the external power supply socket. I used 'Autodesk Circuit' to draw the circuit as shown in the attached picture and to simulate the circuit as shown in the video to prove the code before uploading to the micro-controller. I played around with this until it looked realistic, not that I really know what it is like to see Meg and Mog fly around my garden on a broomstick. Using the code below you can vary the on time of each LED and the delay between each. ![]() ![]() I programmed the the Arduino to flash the LEDs in sequence from bottom to top in a loop. Meg is getting ready for her Halloween tea when disaster strikes and her teapot breaks Meg uses her spells to magic a new teapot, but as usual, all does not go to plan. The small breadboards with the two LEDs were then connected with some old phone cable and placed inside the pumpkins. 24 primary works 38 total works Meg and Mog by Helen Nicoll 4.07 7,745 Ratings 123 Reviews published 1972 35 editions Meg and Mog is the first in the long-standing seri Want to Read Rate it: Meg's Eggs by Helen Nicoll 3.
