I now have an Ardiuno Mega 2560 and 4 Ardiuno Hero UNO devices connected on an I2C bus. I also picked up 9V-1A power supplies, toggle switches, and other bread boards to start building some amazing projects.
It comes with leds, buttons, wires, and other stuff. This board programs in C#.
Look at the 4 packages of resistors? What are they?
I added in this cool chart on how to determine what a resistor is.
1.) You can look at the color bars on it 2.) You can pull out a multimeter and check it
The tolerance is +- 1%. The multimeter reads 1.003kΩ
Red – red – black – gold
Red: 2 Red: 2 Black: 0 Gold: +- 5%
220 ohms or 220Ω
The tolerance is +- 5%. The multimeter reads 214kΩ
LED
LEDs
The LED is 1.5V / 25mA, according to the site. You have a flat side that on the side of the shorter pin. This is the negative. The longer pin is the positive.
The device is 3.3V and 5V
5V: 5V – 1.5V = 3.5V has to be dissipated V = I x R or Voltage = current x resistance 3.5V = 0.025A x R R = 3.5V / 0.025A R = 140Ω
The smallest resistor you can use is 140Ω. Our kit has 220Ω for the LED.
3.3V: 3.3V – 1.5V = 1.8V has to be dissipated V = I x R or Voltage = current x resistance 1.8V = 0.025A x R R = 1.8V / 0.025A R = 72Ω
The smallest resistor you can use is 140Ω. Our kit has 220Ω for the LED. Amazon has the kits.
