It's Here! Chris Odom's Physical Computing & Robotics with the Arduino IDE - Volume Two!

20cm Dupont ribbon wire sets for educational use.

$8.00

These are likely the wire sets you want if you are going to be using them over and over again. Each set has (1) M-M, (1) M-F and (1) F-F 20 cm ribbon. Each ribbon has 40 wires in 4 groups of 10 colors. They are nice and flexible with good quality Dupont ends. I definite notch up.
