Bluetooth car

Hello guys...
To make Bluetooth robot you need

        parts                                                                                     buy links

  • Arduino Uno (any arduino works)                                https://amzn.to/2MUYONt
  • Bluetooth modules                                                        https://amzn.to/2AyfN5t
  • l298N motor driver module                                           https://amzn.to/2YE93ey
  • dc gear motor(100rpm) you can use higher rpm           https://amzn.to/2zsI0Km
  • wheels                                                                            https://amzn.to/2zutthk
  • robot body                                                                      https://amzn.to/3fkIXnq
  • battery pack (12v)                                                          https://amzn.to/2MY3Usi
  • LEDs 
Here is some information about L298N motor driver module

The L298 is a Dual Full Bridge driver that can drive up to 2Amps per bridge with supply voltage up to 46V. It can drive two DC motors or one stepper motors, relays, solenoids, etc.
ESP32 with DC Motor - Control Speed and Direction (With images ...
ENABLE A -- This pin is used to control speed of motor A. by keeping jumper in place, motor A is enable that means motor will spin. by removing jumper motor will stop. by applying PWM to this pin we can control speed of motor A.

ENABLE B -- This pin is used to control speed of motor B. by keeping jumper in place, motor B is enable that means motor will spin. by removing jumper motor will stop. by applying PWM to this pin we can control speed of motor B.

INPUT1 AND INPUT2 -- This pins are use to control spinning direction of motor A. One of the pin is HIGH and another is LOW, motor will spin. if Both is HIGH or LOW motor will not spin. To control the direction EN1 is HIGH and EN2 is LOW, in this condition motor will spin in one direction. if EN1 is LOW and EN2 is HIGH motor will spin another direction.

INPUT3 AND INPUT4 -- This pins are use to control spinning direction of motor B. One of the pin is HIGH and another is LOW, motor will spin. if Both is HIGH or LOW motor will not spin. To control the direction EN1 is HIGH and EN2 is LOW, in this condition motor will spin in one direction. if EN1 is LOW and EN2 is HIGH motor will spin another direction.

And other pins are clearly mention in picture.

here is the Schematic Diagram...

Binary Clock

Hello friends..... here is how you can read binary clock ... here you can see 1,2,4,8 assigned for column. in the picture you can see in HH section first column first led is on so it is one,second column all led is off so 0 SO HERE HOUR IS 10. Now in MM section two led is on so add the assigned numbers. in picture add (1+2=3) and add(1+2+4=7) SO MINUTE IS 37. Then second (SS)  is 49. what you need....                     components                                                                           buy link  Arduino pro mini (you can use any arduino)                              https://amzn.to/2X7O8Qh ftdi programmer                                                                          https://amzn.to/2Tea5vJ   ds1302 rtc module                                                                        https://amzn.to/365RF5D leds                                                                                              https://amzn.to/3fZggNM zero pcb spa
