Messy circuits.
Simple LEDs and a buzzer.
"Argh!" James groaned. "Why.. these wires keep messing up!?"
James was connecting some components to an Arduino Uno controller board. But as he slowly plugging in to the computer, a wire connecting from a LED to the controller pin came loose and began entangled with other components.
In a split of a second, 3 more wires came off together with 2 more LEDs.
Oblivion to the conditions of the circuit, James commenced his software testing. He stared at the screen of his laptop as the controller user interface loaded.
As he executed his program, his frustration grew.
"What's wrong with my codes? He bellowed. “It’s just a simple Blink circuit!”
After peering at his lines of code for ten minutes, James noticed the disconnected components beside his keyboard.
"Where do these come from?" muttered James, shaking his head in despair.
"Now I have to start all over again..."
It took James another 20 minutes to troubleshoot the problem. As he was done, he stared at the circuit, smiling confidently.
“Here it goes.” he breathed nervously.
“Woah! It works!” James jumped up in excitement.
“It is just a simple circuit!” he thought to himself. “What else can I add?”. He looked around and found a motion sensor lying beside the circuit. “Hmmm..”
James connected a PIR (Passive Infrared) sensor to the controller board. After typing on his keyboard for five minutes, he added a few lines of codes to read an input from the sensor. Plugging in the USB cable cautiously into controller, James was sure he did not disconnect any wires or components this time.
“This will be fine!” he began humming softly under his breath.
“Merry Christmas!” he clapped his hands happily like a child.
