What IR source & two terminal Photo transistor can be clubbed to replace either QRD1114 or CNY70 reflective sensor pkg? Answered
I'm referring to - Building of a SPURT BOT(a simple line following robot) submitted by ignoblegnome (See https://www.instructables.com/id/Build-a-SpurtBot-Line-Follower/).
I'm building one for my cousin who's in the 7th grade & found this to be the most simplest & one that looks like its been made by a kid. It looks so, as it has the least number of electronic components. But unfortunately i have been unable to find both QRD1114 & CNY70 reflective sensor packages.
While going through the comments section, i saw a comment by the author himself saying that the package can be replaced with an IR LED & a 2 terminal Photo transistor which happen to be the same components that make up both QRD1114 & CNY70 packages.
I would be extremely thankful to fellow users if they could mention the exact part/component number of the IR LED & a 2 terminal photo transistor that can be clubbed & used instead of QRD1114/CNY70 for the same voltage rating & circuit used in the instructable mentioned above.
I need this info ASAP, THANKS a TON & kindly forgive me for my bad grammar.
