Day 10 - Building Sensors for your Robot

There are two sensors which are line sensor and color sensor
Since we have two people in a team, the work has been seperated
and I chose to make the line sensor


The line sensor is made up by the phototransistor

Phototransistors are phtodiode-amplifer combinations intergrated within a single silicon chip
Follow the schematic
With one of Emitter and one Detector
We will get
The one with the black tape around is the detector and the other one is Emitter
We will not able to see the light came out from the emitter, so we will need to have a camera point at it to see teh light

After finishing the circuit on the breadboard
We went to the fabrication room to solder these component
