Some peoples afraid of high voltage. Some peoples don't want to change their lamp. So here is a basic and safe Bluetooth controlled lamp with SERVO

Step 1:

Necessary Things:


2-)arduino nano

3-)servo motor


5-)Glue gun

6-)Bluettoh module

Step 2: Code



Servo myservo;

int bluetoothTx = 10;

int bluetoothRx = 11;

SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);

void setup()






void loop()


if(bluetooth.available()> 0 )


int servopos = bluetooth.read();





Step 3: Build

tx pin to 10

rx pin to 11

servo to 9

battery + to vcn

battery- to gnd

bluetooth 5v to 5v; gnd to gnd

servo 5v to 5v; gnd to gnd

Step 4: Fınısh

Download bluetooth monitor app and send to correct number

if you want you can build your app

<p>How to build app ??? </p>
<p>For now you can download &quot;bluetooth Terminal&quot; app and connect your device and send correct numbers (how much degre need to turn) like 180 or 10. </p><p>İf you want a app you can build it in mitapp inventor</p>
<p>Here is a guide about app and servo https://www.instructables.com/id/How-to-control-servo-motor-from-android-app/</p>
<p>Nicely done. :)</p><p>Suggestions: Try to use a better camera from next time onwards and be a bit more descriptive when writing the steps. It will be helpful for everyone, especially those who are new to this circuit.</p><p>I have also made this. Check it out.</p><p>https://www.instructables.com/id/How-to-Make-Bluetooth-Controlled-Lamp/</p>
<p>İts my first instructable. Thanks for advice. I will try :D</p>
<p>Sure :)</p>
<p>Nice. I need one of these in ever room of my house.</p>
