I made the game that I used 12 LED for in ATtiny13a.
The memory of ATtiny13a is very little with 1KB.I tried the challenge I make games in 1 KB.
I made very small Simon Say using ATtiny13a and the mini breadboard.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Circuit Diagram
Circuit diagram is using a large breadboard :-)
1x Mini breadboard
1x CR2025 CR2032 3v button battery holder
1x 10K resistor
1x 1.1K resistor
1x 2.4K resistor
1x 8.2K resistor
4x Button(Tactile switch)
4x 3mm LED
Blue LED requires a high voltage . It will not emit light immediately .
Step 2: Sketch
Step 3: ATtiny13a Put on the Mini Bread Board.
Please note the orientation of the ATtiny13a.
Step 4: Buttons
Please note the orientation of the button .
Step 5: Resistor
It does not work and choose a different resistance .
Please choose the correct resistance . Or modify the sketch .
Step 6: LEDs
Please choose your favorite color of 3mmLED.
Blue LED requires a high voltage . Recommended red LED and yellow LED is .
Step 7: Jumper Wire
Carefully so as not mistaken .
Step 8: CR2025 CR2032 3v Button Battery Holder
Step 9: Assembling Video.
have fun :-)
