DTMF Controlled DIY Kit

This Do It Your Self kit comes along with an Arduino Uno board, motor driver L293D, DTMF module, DC geared motor, robot chassis, caster wheel, nut-bolt pack and a screw driver. DIY kit is for all robotics enthusiasts starting from beginner level to expert level at economical cost. For example it is easy to assemble and operate a robot from a remote location or wirelessly using mobile phone and kit. Dual tone multiple frequency DTMF shield is used to decode the frequency generated from our cell phone which help microcontroller. The shield is based on MT8870D IC which a DTMF receiver that has two section one band split filter and other is encoder. DTMF IC simply generates two frequency corresponding to a single number pressed on keypad.
