hello fnds,i am buliding a line maze solver. for tat iam trying to first implement CIRCUIT OF LINE FOLLOWER. I found a sample circuit from a site which i have attached.
1. In these circuits he has used photo transistor. But in my locality i could find only THREE LEADS photo transistor where as in the circuit he has used two lead transistor. can i use the three lead phototransistor ? if yes ,how ?
2. Will the circuit work with a normal photodiode(reciever) in place of the phototransistor ?
3. can i have a better way of designing my line sensor ? it needs to be efficient with better output (3.5 v to 5v).... can anyone suggest some good techniques ?
the circuit i have attached are taken from http://www.pololu.com/catalog/product/958
