Off to the races: debugging! What are voltage, current and resistance? How are they related? And why should I care? In this chapter, you will learn about voltage, current and resistance and how they interact with each other. This will help you understand how your circuits are working, and how to make adjustments to them. […]
Read More →Build the circuit step by step In order to build the basic circuit described in this chapter, you’ll need the following parts. You’ll need these parts: 2 red LEDs 1 220 ohm resistor (red, red, brown, gold) Jumper wires Breadboard. Arduino Uno USB A-B cable Computer with Arduino IDE This circuit is quite similar to […]
Read More →Debugging: what do I do if the LED is not blinking? If your LED is blinking and the upload worked, move on to the next page. But what if the LED didn’t light up? Just like we used Debugging to search out any issues in our hardware and circuits, we will do the same throughout […]
