@@aslamhossain1 Thank you! I have another question if you dont mind... Does it still work if I dont use buck and boost converter? does it overheat? does it not work at all? I am new to robotics and i am curious!
Buck converter to provide 5v stable power for arduino and ir sensor array. Boost converter to convert the input (7-8v) to 12v stable power for motors so that the motors can rotate at higest rpm all the time. If you don't use boost converter then the speed of motors will reduce according to the discharge rate of the batteries. As my motors are 12v rated hence i've set the output at 12v. You can set according to your motors voltage rating. Thank you
Hey if I use arduino uno will it work? (I think so it will) and if I use 12v, 1000rpm will it will be useful for speed and I want to participate in a comp so can I make this or will I need sonar
Excellent Work sir!, sir can I ask? in your schematic diagram the IN1 is pin 7, and IN2 is pin 4 but in the code the IN1 is 4 and the IN2 is 7. is it a mistake? where should I side in the diagram or in the code?
Follow the the code. When my motor was running in reverse direction then i've interchange the control pin in the code rather than changing in the circuit. Or you can interchange the motor terminal.
I have this annoying issue. S3, or the middle sensor, is the only sensor that's able to detect the contrast between black and white. Basically it's the only sensor that detects the line. The other sensors (S1, S2, S4 and S5) do not detect the contrast between black and white, and instead output 0 if it detects nothing (I face it away from anything or high up in the air) and 1 if it is in close proximity with anything, regardless of contrast or colour. Please help! Note: I'm using a TCRT5000 5-channel Line Tracking Module. It should still essentially work.
@aslamhossain1 TCRT5000 5 channel Line Tracking Module with Bump and Obstacle Sensor. I don't use the bump and obstacle sensors. The distance from the ground to the sensor fits the designated range the sensor is capable of. What's happening is that the middle sensor can detect the black line from a height of around 3 cm, but the other 4 sensors only detect the black line when it's touching the line. The potentiometer that supposedly adjusts the range doesn't detect any changes.
But usually lfr competitions have obstacle avoiding in it,so which would be more feasible adding 3 sonar on 3 sides or adding a sonar on the top of a servo?
@@aslamhossain1 can you Please tell me which would be more feasible for those competitions,adding a sonar on a servo or adding three sonars on three sides on the lfr?
