Pahelp po.. gusto ko kasing gumawa ng line follower based dito kaso di ko maatim na bilhin yung l298 dahil 300pesos sya.. yung L293 naman wala akong mahanap. pede po bang gumawa na lang ako ng h-bridge using discrete components. I understand na kapag ginawa ko to babaguhin ko din yung nasa code involving yung software PWM dahil wala na yung enable1&2 pins.

Isa pa po, wala na kasi akong mahanap na old mouse na may sensor pairs. so bumili ako ng IR Led and phototransistor. Di ko naman maidentify yung pins nung phototransistor kasi di ko alam yung exact part name nya so i have no idea kung anung data sheet isesearch ko sa net. 2 pins lang po un tapos yung isang pin may black at may nakausling metal sa side. help naman po iidentify yung pins nito mga bossing.

May L293D sa E-gizmo kakabili ko lang nung isang buwan.

sir magkano yung L293 sa e-gizmo? problem ko lang sa phototransistor is yung pins nya. di ko kasi alam panu i-identify yung collector and emitter nya.. di ko din alam if NPN or PNP sya
