PIC16F84 Development Board PLAY-PIC

New to PIC programming a circuit that will be beneficial to your friends. Designed to work with PIC16F84. On the board buttons, LEDs and available in seven segments. Thus, when a trial programs çalıştırabilirsiniz.ayrı easily make links to outside input, LCD display and an external programmer for connection of the card’s internal connectors bulunmakta.ayrı var.9-24 volts DC voltage regulator circuit can be fed with a source.

PIC16F84 PLAY-PIC

PlayPIC Circuit Properties

S1 switch controls the card. When the card works, the green LED (led9) is on.

Switch S2 resets the microcontroller.

S8 switch turns LCD screen on and off

The S9 switch allows you to use whatever you want by controlling the 8-LED group or 7-segment.

S3-S6 buttons are RA0-RA3 inputs. SW2 dip switch controls the authorization of these buttons.

SW1 dip switch(four) controls the following features.

1. Connects RB0 lead (when used as output) to LED1.
2. Connects terminal RB0 (when used as interrupt input) to button S7.
3. Connects the S7 interrupt switch to the anti-duplication circuit.
4. Connects RB0 (when used as output) to buzzer.

The dip switch must be in position 1000 or 0100 or 0110 or 0001.

JP4 is a screw type 6 pin output connector. It can be used for external inputs to be connected to the RA0-RA4 port. When used, the S3-S6 buttons must be disabled with the SW2 switch. The last screw is ground. JP2 is a 14-pin test terminal.

The signal traffic in the circuit can be observed here. The last pin is ground. JP1 is 18 pin integrated socket. JP3 is a 14-pin connector for the LCD module. The screen light can be adjusted with the R21 pot. The board can be powered by any source between 9-12 volts.
