A 4-way traffic intersection which currently has stop signs to all lanes of traffic flow is being replaced with a flashing red light (one light facing towards each lane of traffic). Design a flowchart in Microsoft Visio that will start a program to flash a red LED on and off when a button is first pushed. The LED will flash on for 1 second and off for 1 second. When the same button is pushed a second time, the program will stop.
