Machan Two wheels line following robot kenekuta PID use karanne kohomada bn? Poddak tutorial ekak dapnko kohomada program eka run wenne kiyala..
Kp, Kd values ekka error eka ganne kohomada? Kohomada errors calculate karanne?

Thawa mata oona..
Sensors anuwa, motors wala pwm speed eka wenas karanne kohomada kiyna eka.. mokada left side, right side hareddi eeka oonane..

First of all, does the robot likes it? Don't use anything on him against his will or he will switch himself to terminator mode and then you know what will happen, right? I'm just kidding.

BUMP!

Yeah.. I'm sure he will not switch to terminator mode

ewala description balahan , welawakata un program eke download link eka description eke danawa , eka down load karan study karala eka moify karahan ubata ona widihata.

ewala description balahan , welawakata un program eke download link eka description eke danawa , eka down load karan study karala eka moify karahan ubata ona widihata.

Good idea.. balamu ehemath gemak gahanna puluwanda kiyla

machan meke error eka gannawa.. ita passe laaterror=error walata..
Motorspeed eka ganiddi KD(error-lasterror )wenawa.. e kiyanne eeka always 0 ne bn.. ithn eeka wadak na ne.. ai bn ehema karala thiyenne?

ow ethana awulak thiyenawa machan error eka lastError ekata ekata assign kalata passe error eke value eka apahu update karala ganna ona. Oya lestError kiyana eka error kiyana udin dala loop ekata udin define kalanam hari wage.
