Arduino Report #5: Project 6--Strobe Light

Additional Parts:

1. High Intensity 1W LED
2. 220 Ohm Resistor
3. 4 Ohm 1 W Resistor
4. BD139 Power Transistor
5. 10K Linear Potentiometer

Time to Complete: 15 minutes

The purpose of this project is to make a seizure-inducing strobe light. The frequency of the flashes is controlled by the linear potentiometer (pot). The set up of this project is nearly identical to the High-Brightness Morse Code Translator with the exception being the new blue pot. Turing the knob on the blue pot changes the value of the resistance between the middle pin and the pin on either side. This gives a variable input signal to be read by the Arduino through one of the analog inputs. The strobe light program take the value of the input from the variable resistor and translates it into a delay time for turning on and off the LED. A video is below. These LEDs are insanely bright. 


For the purpose of learning as much about the Arduino and connecting new components, I will skip the next two projects for now and will continue with the LED dice.
