Inventor’s Kit
I found this kit on Facebook advertised for $29. The Advanced Hero’s Kit. You can buy more components from them to expand you building.

Drivers and software
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
So here is the first resistor.
Brown – black – black – orange – brown.
Brown: 1
Black: 0
Black: 0
Orange: x 1000
Brown: +- 1%
100,000 ohms or 100kΩ
The tolerance is +- 1%. The multimeter reads 99.6kΩ
Brown – black – black – red – brown.
Brown: 1
Black: 0
Black: 0
Red: x 100
Brown: +- 1%
10,000 ohms or 10kΩ
The tolerance is +- 1%. The multimeter reads 10.01kΩ
Brown – black – black – brown – brown.
Brown: 1
Black: 0
Black: 0
Brown: x 10
Brown: +- 1%
1,000 ohms or 1kΩ
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.
