finished robot frog.

Now that Frogbotic’s hardware is complete, we will focus on pro-
gramming the robot to read input from the limit switch sensors,
control the leg servos, make sounds, and turn the LEDs on and off.

Programming and Experiments
with Frogbotic

To test the main controller board, the PIC 16F84 will be pro-
grammed to flash the LEDs, make frog-like noises, and then start
rotating the servos. This will ensure that all of the components
have been correctly soldered to the board and that power has been
connected. The first program is called frog-test.bas and is listed in
Program 4.1. Type the program into your favorite text editor and
