I have watched a lot of videos related to making a dtmf controlled robot but all thise show a 9v robot which cant be so practical. So i want to make a powerfull one. Could anyone reccomend the components i will reqire
You can find a lot of examples/tutorials online. Here is some examples :
]DTMF CONTROLLED ROBOT USING ARDUINO/:m]
]DTMF Controlled Robot without Microcontroller/:m]
]DTMF Based Controlled Robot Vehicle/:m]In general, you will need the following components :
]A DTMF (Dual Tone Modulation Frequency) Decoder IC/Module : you can use for example the Dual-Tone Multi-Frequency Signaling Decoder Shield./:m]
]A microcontroller : you might be interested in using an Arduino UNO Microcontroller Board/:m]
]A 2 channels DC Brushed Motor Controller : here is our Brushed DC Motor Controllers category for your reference and here is a link to a nice blog post explaining how to choose an appropriate motor controller./:m]
]For motors, you can take a look into our Brushed DC Motors category. You might also be interested in purchasing a ready-to-use robot chassis kit as the DFRobot 4WD Arduino Mobile Platform/:m]
]Finally, you will need a power supply. Since the robot would be mobile, you might need to use a battery as power supply. The most popular battery packs used for robotics are LiPo and NiMH/:m]
Hope this helps,
