Anatomy of Sajilobot



 The different electronics components found on Sajilobot are as follows:

1. Microcontroller - Brain of Sajilobot




2. Motor Driver - Helps to control Dc motor (IC)



3. Relay Module - Electromechanical switch for automation



4. Resistor - Limits the flow of current

 Lets calculate the resistance of resistor using the following Charts




5. Switch - Changes the state of the circuit for eg On and Off.



6. Diode- one way Street for electricity



7. LED - Light Emitting Diode

8. LDR- Light Dependent Resistor



9. Capacitors - Load balancing in the circuit



10. Transistor - Amplifies the signal acts as a switch and even Voltage Regulator



11. Header Pins - Helps to connect Wires to sajilobot




12. PCB - Printed circuit Board


# What is a PCB?



-> A PCB is a printed copper connections to connect our elecrical/electronic components to perform Specific Functions.
