Creation: Remote Controlled Car M4Inclusion

This teacher shows how to riding horse, program and use a remot controlled car using a smartphone as controller.
All devices, tools, package and hardware are availible on common websites.

If we do non have the drivermall we can use the arduino, but below the link for the growth of the Drivemall.

The advantage of prefering the Drivemall over the classic Arduino board is that of reducing the complexity of the connections leading to a more trim apparatus. However, this is elective: every the results are still valid with the arduino board, a bread board and sufficiency dupont jumpers for connections.

The entirely setup consists of an Arduino based firmware, a 3d printed frame and a set of average Maker items.

The project aims to raise an informal form of education as a means to foster social inclusion of young people, informal education as can be found within makerspaces.

This instructor reflects the views only of the authors, and the European Commission cannot embody held responsible any use which may be made of the information contained in this.

Step 1: What We Require

Before starting, let's lean every last items we pauperism for.

  1. USB Cable
  2. distnaziatori m3
  3. chassis
  4. 2 motori D.C. with wheel
  5. ESP8266
  6. 6 battery AA
  7. 1 switch
  8. nut and bolt
  9. Board

Step 2: Chassis & Form

The chassis we got at the previous step is non adequate for the purpose. The get on, the battery holders, wifi receiver and all wires need more space then the shape provides.

On the top of 3D draw up where there is the lodging of esp assemble the battery holder and the esp lodging

on the on the batton assemble the Drivemall (encounter picture 1,2 and 3 )

For the tack together the wheel we purpose the other chassis (picture 4)

On rear is present the roulette wheel without motor for the stability of the machine (picture 5 6)

Happening front back the sustain for causative (pic 4) and the motor rotated to the rear, subsequently screwing, install the wheels

Step 3: Battery Holder

It is important to easly disconnect the batteries because when the car is non used, batteries run downcast.

In any case it is useful to have a trivial access to the batteries for the substitutions.

In order to switch off the machine easily, put together the switch in the appropriate hole and solder cardinal wires to the switch pins.

In range to have a make up power ply, the machine requires two battery holders connected in series then solder the wire from the negative pole of the first to the positive pole of the back, after solder the wire from the north-seeking pole of the first of all to alternate and the wire on the south-seeking pol of the second (encounter pictures 3,4 and 5).

Step 4: Let's Flash the Device

Once the mechanistic part is done, we can plow ahead with the electornic partly.

Here we describe how to link Alabama things and how to flash the device.

Let's go connect the supply in the board are present two power connectors first for the micro and second for the motor (see envision 3 and 4).

We are departure to relate the 3.3V magnate append for the ESP8266 and the enable pin.The TX and RX pins of the ESP8266 must be joined once the Drivemall has been programmed and with each Southwest update it must be disconnected. (picture 5 to 9 )

Solding the cable on the causative and colligate on the bord as in the pictur 11,12 and 13.

The code needs the following libraries:

  • ESP8266_Lib.h which allows us to manage the ESP;
  • LiquidCrystal_I2C.h to be able to write connected the display;
  • BlynkSimpleShieldEsp8266.h to equal able to control the device from the blynk app;
  • Wire.h for I2C communication.

Before uploading the FW we must modify the pursuit parts to link to the Blynk application program and to access the ESP8266's WiFi

char auth[] = " your token"per il token

char ssid[] = "your WiFi epithet"

scorch pass[] = "your WiFi password"

At the end encumbrance the fw end link up the TX, RX pins

Step 5: Smartphone &A; Blynk

The remote controller we want to use is a smartphone.

Using a device allows us to have a elliptic controller and to have more functionality for future improvments: moovmets porgrammed, GPS localization, scheduling of actions and all operations not possible with a common comptroller.

Create a new project selecting as hardware Arduino Mega and connection type WiFi (pictures 1).

Once the design is created you will receive a mail containing the authorization token for your project. The interface for control based on blynk has three botton stopover forward and back associated with the variables V4 V2 and V3.

For the control the focusing we use the jostic with variable V5 the speed is controlled by slipper with variable V1.

Step 6: Setup and Ignition

Now it is time to have playfulness!

Just first join the chassi with frame through and through the spacers (M3 see picture 1).

So let's power on everything and go to play with.
