Question

Design and implement a functional traffic light using a push button to act as a cross walk. Components one RGB LED Lights, two 330 ohm resistor, POT, Temperature Sensor, Arduino, and a bread board Description: Use a POT and a Temperature Sensor to enable the Red and Green Legs of and RGB LED. RGB LEDs have three legs the (R)ed, (G)reen and (B)leu legs. c programming language
