DTMF is a Dual Tone Multiple Frequency decoder module which has a MT8870 DTMF decoder IC which decodes DTMF tone signal to digital signal that are acceptable for arduino digitally. Here an aux wire is needed for connecting DTMF module to phone.

Required Components:
  • Arduino UNO
  • DC Motor
  • Mobile Phone
  • DTMF decoder Module
  • Motor Driver L293D
  • Battery Connector
  • Aux wire
  • Robot Chasis with wheel
  • Connecting wires


Features:

  • Remote section: This section’s main component is DTMF
  • Here we get a tone from our cellphone by using aux wire to DTMF Decoder IC namely MT8870 which decodes the tone into digital signal of 4bit
  • Control Section: Arduino UNO is used for controlling whole the process of robot
  • Arduino reads commands sent by DTMF Decoder and compare with define code or pattern
  • If commands are match arduino sends respective command to driver section
  • Driver section: driver section consists motor driver and two DC motors
  • Motor driver is used for driving motors because arduino does not supply enough voltage and current to motor
  • So we add a motor driver circuit to get enough voltage and current for motor
  • By collecting commands from arduino motor driver drive motor according to commands.

The PCA9532 is a 16-bit I2C-bus and SMBus I/O expander optimized for dimming LEDs in256 discrete steps for Red/Green/Blue (RGB) color mixing and back light applications.The PCA9532 contains an internal oscillator with two user programmable blink rates andduty cycles coupled to the output PWM. The LED brightness is controlled by setting the blink rate high enough (> 100 Hz) that the blinking cannot be seen and then using the dutycycle to vary the amount of time the LED is on and thus the average current through the LED.

Features:

  • 256 brightness steps
  • Input/outputs not used as LED drivers can be used as regular GPIOs
  • Internal oscillator requires no external components
  • I2C-bus interface logic compatible with SMBus
  • Internal power-on reset 16 LED drivers (on, off, flashing at a programmable rate)
  • Two selectable, fully programmable blink rates (frequency and duty cycle) between 0.591 Hz and 152 Hz (1.69 second and 6.58 milliseconds)

Applications:

  • Backlighting
  • RGB Color Mixing
  • Sensors Control
  • Power Switches
  • Push−buttons
  • Alarm Systems

Output power:
  • 10A-120watts per channel @12V
  • 10A-240watts per channel @24V
