In today’s lecture on our Design Projects, we were advised that the blink speed of the LED will never be the same as what we set it in the programme. If we program an LED to blink for 0.1 seconds, for example, it might blink for 0.134 seconds. I added delays at the beginning and the end of the LED pattern because my lecturer advised me to do it. The purpose of these delays was to make the testing device calibrate itself.
We compiled the program and tested it. The LED’s were working fine, so we were expecting that we were going to get our binary number (82). When we tested our circuit in the LED Flash challenge Validator, we did not get our binary number. I knew that there was something wrong with my programming, and I tried to figure it out, but I could not. I watched Ted’s binary video again, and I noticed that I forgot to put in zeros before and after the code. I inserted the zeros and tested our circuits again. The circuit worked well, and we got our binary number.
