Light Following Robot

Aim:

The main aim of the project is to make a robot which will follow the lights for moving.

Components Required:

Sr. No	Component	Quantity
1	TeBoT and Cable	1
2	LDR Modules	2
3	Jumper Wires (M-F)	6

Connection and Code Upload:

Step 1: Connect the TeBoT with your device and turn on it.

Step 2: Select the board and port, then upload the code.

Warning: If you face any issue while uploading the code, first “OFF” the TeBoT. Next, turn “ON” the TeBoT. Press the “BOOT” button for a short time then press the “RESET” button once. Then release the “BOOT” button.

You will get a drive. Then upload the code.

Step 3: Now take two LDR Modules and attach on TeBoT with the help of double sided tape.

Step 4: Now connect the LDR modules with TeBoT.

LDR Module	↔	TeBoT
VCC (Left LDR)	↔	VCC (1st pin of ultrasonic port from right to left)
GND (Left LDR)	↔	GND (1st pin of ultrasonic port from left to right)
VCC (Right LDR)	↔	VCC (4th pin in Bluetooth port from up to down)
GND (Right LDR)	↔	GND (3rd pin in Bluetooth port from up to down)
OUT (Left LDR)	↔	Pin No 15 (2nd pin of ultrasonic port from right to left)
OUT (Right LDR)	↔	Pin No 14 (3rd pin of ultrasonic port from right to left)

Now, Turn on TeBoT. Then press the button (B / D22). When you show the light on left LDR, the robot will turn left and when you show the light on right LDR, the robot will turn right. Also when you show the lights on both LDR, the robot will move forward.

❖ This is happening because of the detection of light by LDR sensors.

Conclusion: From this project we got the idea about all components, connection of those components and made Light Following Robot.
