Robot intelligent : Suiveur de ligne – Circuit éléctronique

The connections you need to make are also piece of cake. You just need to connect to sensors as shown in the circuit diagram below. The motors remain connected as they were when you made you made your first ever Smartphone controlled robot. No extra work!

Let’s first connect the IR sensor on the right.

• Take a red male-to-female jumper wire and connect its female end to the VCC pin on the sensor. The VCC pin is for the 5V supply. Then, insert the other end in the 5V pin on evive.
• Now, take a black male-to-female jumper wire and connect its female end to the GND (ground) pin on the sensor. Then, insert the other end in the GND of evive
• Next, take a yellow male-to-female wire and connect it to the OUT pin on the sensor. Connect the other end to Digital pin number 3 below the breadboard.

The sensor on the right is connected. Now, let’s connect the sensor on the left.

• Take another red male-to-female jumper wire and connect it to the VCC pin on the second sensor. Then, insert the other end in the 5V pin on evive.
• Next, take another black male-to-female jumper wire and connect it to the GND pin on the sensor, and insert the other end in the GND of evive.
• Then, take a yellow male-to-female jumper wire and connect it to the OUT pin. Connect the other end to Digital pin number 2.

And you’re done. The circuit is now complete.
