RE: Hello, My name is Mike, and Welcome to Learn Electronics!
Hi Mike! Welcome on board!
As you are in electronics, do you think it is difficult to make the following:
Board 25 leds ( 5 x 5 ). I want they turn on like playing the snake... One after another in a special order.
It could be possible to make the letters appear too...
Thank you!
Hey evyxxx, the project you described is manageable for an electronic beginner. In case you are an absolute beginner you should start with a less complex project to get encouraged by the faster achievements. You could start with fragmenting your project in multiple projects. For example start with coding the 5x5 game and letter logic in Python.
This is totally possible. :)
I guess so... What do I need to make it? Interested in building this project on #steemit? Later I will show the base of the lamp I want to make :)
Perhaps. It will have to come a bit later as I already have a full schedule for what I will be posting here. But I think a project like this is quite doable. :)
Hey @evyxxx, the most straight forward approach is wiring up each LED with a single output pin. Therefore 25 ouput pins are needed. I recommend using an Arduino Mega 2560 or clone. This board has enough GPIOs to get you started. Use a Breadboard to directly wire up your LEDs. Do not forget the LED series resistor for each LED to limit the current. There are LEDs with integrated series resistor.
Warning: Usually signal outputs should not be used to provide current, but your use case will not exceed the current limitations (https://playground.arduino.cc/Main/ArduinoPinCurrentLimitations Atmel ATmega2560/1280/640 (MEGA) Current Specifications)
