Picaxe Logicator Sample Programs & Software

store_high_score.plf

• This program uses EEPROM location 1 to store a high score.
• The program counts button presses, if the button is pressed more times than the high score then the high score is updated and stored back in EEPROM location 1.
• LED’s are used as indicators. Amber = waiting for a button press, red = not a new high score and green = a new high score.
• The high score and the score are both displayed on an OLED screen.

eprom_store_timer_value.plf

• This program READS the value stored in EEPROM location 2 and displays it, then starts a timer when the button is pressed. When the button is pressed again the timer is paused and the timer value is stored in EEPROM location 2.
• This illustrates how values stored in EEPROM are preserved when the power is switched off.

random_seed.plf

• Because the random number always starts from the same seed this program generates random numbers but does not display them until the button is pressed.
• The numbers that are displayed therefore appear to be totally random because the delay until then button is pressed will be different every time the program is run.

Light follow.plf

• A simple light follow program using 2 LDR’s on the front of the MicroBot. If the difference between the two readings is great enough the MicroBot will veer towards the higher reading. otherwise it will keep moving forwards
• The inbuilt LED’s indicate which LDR is receiving the most light.
