Description
Created this maze game with some school colleages. thought to share it with you.
Joystick controlled maze game.
The button with led ring acts as a power supply check. Each servo has its own power supply (Lm7805). if both 5volts are present the led ring will light up. Button itself has no function but can be used later.
DXF of the plexiglass plates will be added soon.
STP of the maze itself and maze frame will be added soon.
What you need for the frame:
20x20 Alumunium profile in sizes:
4x 260mm
4x 125mm
4x M4 profile mounts
m4 bolts
i added a picture of the frame seperately
I recommend to let it size at the factory and not DIY.
1x led button ring D16mm short 5V
Print 4x legs (60% 0.15)
Print 1x frontpanel (60% 0.15)

-----Elektronic parts----
The pcb fits perfectly on the arduino as a stack. the holes of the arduino are copied into the PCB. this way you save space and wires.
The LM7805 need to be placed flat ontop on some sort of heatsink. we used a piece of bended aluminium.
3x cap 0.33uF
3x cap 0.1uF
3x res 220R
2x res 10kR
2x lm7805
12v-24v 1,5A adapter for input
switch (optional)
fuseholder (optional)
usb to usb panel mount connector (optional)
2x 180* servo i recommend expensive FAST reacting servo's. yes aliex cheaper ones will work asswel but its not great. recommended ones are listed below.
1x joystick
