🥳🥳Today we got our own Arduino kit & Solder kit !!!!🥳🥳
Circuit 1: Fade
Materials:
- 1 * Arduino Uno
- 1 * USB A to B cable
- 1 * breadboard
- 1 * LED
- 1 * 220 ohm resistor
- A handful of jumper cables
It’s not complex but still interesting to see the LED go from dim to light and back to dim in a regular cycle.
Also, we are able to change the duration of each round, so I edit it to twinkle faster.
Circuit 2: toneMelody
Materials：
- 1 * Arduino Uno
- 1 * USB A to B cable
- 1 * breadboard
- 1 * buzzer
- 1 * 10K ohm resistor
- A handful of jumper cables
It’s also not difficult and the speaker was able to play a certain melody.
Circuit 3: Speed Game
Material:
- 1 * Arduino Uno
- 1 * USB A to B cable
- 1 * breadboard
- 1 * buzzer
- 2 * LEDs
- 2 * 220 ohm resistors
- 2 * 10K ohm resistors
- 2 * pushbuttons
- A handful of jumper cables
It’s the most complex and interesting one of all the three circuits. But under the guidance of a diagram example, I made it successfully. It is also a device for two people to compete with each other and gives its feedback through light and sound.
Mine and Cathy’s!
Now it’s time for competition!
Question 1: I suppose adding some more LEDs and a stress sensor. LEDs of different colors represent different actions. For example, besides the red and green bulb representing different players, we can add white for quick pressing and yellow for strength pressing and code to make them light randomly. So players will have more interactive experiences
Question 2: The 10k resistor acted as a pull-down resistor ,which makes the input pin biased to GND when the circuit is in an open state and prevents shortcuts.
