lets build it
all off you know about the t rex aka dino game of google and it famous as no internet game.
the game is very simple just avoid the obstacles by jumping and its like super Mario run.usually to jump we use space bar manually.that's very old school for me...
so in this tutorial, I am going to show you how to make that in automatic that is an automatic controller.
please watch the making video for more details
here we want to detect the obstacle and jump to detect the obstacle I am using an LDR
so how an LDR detect that kind of obstacle?
the resistance of LDR changes according to light that is when the dark time the LDR resistance is very high and vice-versa. so our obstacle is dark in colour so we can get different analog values . with that value with the help of a controller we trigger a servo.
servo is used to press the space bar. so that's the working principle
you can use any arduino
I am using sg90
please watch the video
first, connect VCC of the servo to 5v and ground to ground
then I connected PWM pin to Arduino pin 9
connect LDR to pin a0
I am using the analog read function of Arduino and I give conditions for servo triggers
please watch the video .if you have any doubt please comment it below
