Introduction: Smart Phone Control Arduino Robot
It is a smartphone control Arduino robot project. for this project, I have made a PCB so no problem with meshy wire connections.
This board has dual motor driver & some extra Arduino pins, 3V,5V,GND out so Using this PCB you can make line follower, obstacle avoider, edge finder, voice control & other Arduino robots by changing Arduino code. In this post, I am describing how to make Bluetooth control Arduino robot or car.
Step 1: You Need to Make
To make this project easily I have designed a circuit & make it in a pcb
you can download & order PCB from here
- Arduino nano
- L293 D ic, ic base
- Capacitor – 100mf/25 v – 2pcs
- Male, female header pin
- Terminal block- 4 pcs
- Led & 1k resistor
- Hc 05 Bluetooth module
- 9 volt battery or power bank
- Any 2wd robot chassis with two 150rpm geared motor
Step 2: Assembling of Components & Connections
The assembling of components is very easy. All components value, polarity is printed in the PCB so just follow the printed components on the pcb.I have used female header pins for Arduino nano & 16pin IC base for L293 D IC.
Step 3: Software Part
We have to program Arduino nano using Arduino IDE
Here is the Arduino code & more details
the above code is for only Bluetooth control robot but using this circuit board you can make different types
of Arduino robot by changing the code & adding some sensors
Download Bluetooth RC controller from play store
I am using Arduino Bluetooth car controller app Bluetooth RC controller from play store but you can use any Bluetooth controller app but need some changes in Arduino code.
The video of this project may help you.
Best of luck
