Arduino - Challenges

Here you can challenge yourself to build more projects with the Arduino board. We will either give you the electrical circuit assembly or the programming code.

If you have questions or are looking for the solution to challenges:

Challenge 1 - Two leds light alternately

Material you will need:

2x leds of different colors
2x 220 Ohm resistors

Hover the mouse over the question mark

Challenge 2 - Electronic dice

Material you will need:

7x single-color leds
7x 220 Ohm resistors
1x push button
1x 10 KOhm resistor

Hover the mouse over the question mark


Challenge 3 - Simple Traffic Light

Material you will need:

1x Green led
1x Yellow led
1x Red led
3x 220 Ohm resistor

Rules:

The green led should start on
It should turn off after 5 seconds and the yellow led lights up
The yellow LED should now flash 5 times at 100ms intervals
The yellow LED should now stay on for 1 second
The yellow led turns off and the red led lights up for 5 seconds
