Introduction: Stroboscope for 20 $
Here are a tutorial for make stroboscope.Stroboscope improve your party.
For this test I have used 9 CMS led but it's possible used 90 led (9 by exit of arduino).It's possible used basic led for make this stroboscope.
Step 1: Material
Material :
-1x Arduino Nano
-1x Sheet Test PCB
- 1x Connector 9V Battery
- 1x Potentiometer 10 K
-1x 9V Battery
-1x Power Switch
Step 2: Electric Sketch
Battery is connected with the power switch and arduino card (switch for + and GND for -).
Power switch is connected with the battery and arduino card (battery for + and VIN for -)
Pentiometer is connected with arduino (5.5v,GND and A5 )
Leds is connected with arduino (GND und A2)
Step 3: Welding LED
Identify the positive and negative terminal electic with multimeter and weld led on sheet PCB.
Step 4: Repeat Operation
Repaat this operation to connect same terminal electic .
Step 5: Dispostion of Element's
Put arduino, potentionmeter and switch power on PCB card.
Step 6: Return PCB Card
Return PCB card and connect with wire and tin terminal electic (+with + and -with-)
Step 7: Connect Pentotimeter
Connect pentotiometer with wire and tin:
VCC(wire green) : 5.5v
GND(wire white): GND
DATA (welding) : A5
Step 8: Connect CMS Led and Arduino
Connect with wire and tin: arduino and led
Connect terminal electic positive with arduino(D2)(wire red )
Connect terminal electic negative with arduino(GND)(wire blue )
Step 9: Connect Battery and Switch Power
Connect with wire and tin :
Connector 9v :
- positive with switch power
-negative with arduino (Gnd(2))
Switch power:
- right spindle with battery(+)
- middle spindle with arduino(VIN)
PS: (Gnd(2)) has bin located next to VIN.
Step 10: Connect Arduino With Computer
Connect Arduino with Computeur and enter this programme in the Arduino Nano.
<p>int potPin = 5; // pin d'entrée de lecture du potentiomètre<br>int ledPin = 2; // Pin de sortie la LED int val = 0; // variable du potentiomètre</p><p>void setup() { pinMode(ledPin, OUTPUT); // Déclaration de la pin de la LED en sortie Serial.begin(1); // Activation de la sortie serie(facultative) }</p><p>void loop() { val = analogRead(potPin); // lecture de la valeur du potentiomètre digitalWrite(ledPin, HIGH); // Active la sortie de la LED delay(val); // Attente de la valeur recus digitalWrite(ledPin, LOW); // Désactivation de la sortie de la LED delay(val); // Attente de la valeur reçus // Partie facultative Serial.print("Valeur : "); Serial.print(val); Serial.println(); }</p>
Step 11: Results
It's finish ! Now it must be shell for stroboscope in 3D printing or metal for exemple.
Step 12: Thank You
Thank you for your attention and sorry for my english !
I am french young student, I have a bad english thank for your comprehension !
Best regards Paul le bricoleur.
