Timer Tamiya 3 Lap dan 3 Jalur / Line + Fitur Lastlap
Pada kesempatan kali ini saya akan menjelaska mengenai bagaimana cara membuat sebuah alat timer lomba tamiya untuk 3 jalur / Line, alat ini juga dibekali fitur lastlap jika terjadi mobil tamiya yang keluar jalur maka tombol lastlap diaktifkan. untuk lebih jelasnya berikut adalah koding dan skemanya.
