WebInsert a red, yellow or green LED into the circuit as shown one at a time. Try exposing the three different color LEDs from your ADALP2000 Analog Parts Kit to different light sources such as standard incandescent, florescent and LED lights held at differing distances from the LED sensor. Observe the voltage waveform seen at the collector of Q 1 ... WebThe standard red LED is the "indicator LED" - it lights up when the right color is detected. Ask Question Download Step 2: Build the Circuit The schematic is rather simple, and in general form, is shown below. The RGB LED is externally powered by a PWM signal.

When computing the value of a current limiting resistor for a single LED, the basic form of Ohm's Law — V = IR — becomes: where: V batt is the voltage across the resistor and the LED. V led is the forward voltage of the LED. I led is the forward current of the LED.

Since we don't know the resistance, you should do your difference in volts divided by your current in amps: V/I = R. I did (5 - 1.6)/0.1 which gives me 34 ohms. The two common resistors are 33 and 39 so I just went with the higher one to be safe. cdg to westin vendomeWeb1. feb 2007 · A red LED needs about only 1.8V so using a 9V battery wastes 7.2V. Two AA cells (3V) can power a red LED about 5 times longer than a 9V battery, are about the same size and cost much less. My 3V LED Chaser project uses two AA alkaline cells and its red LEDs blink brightly for about 1 year.
