As a programmer, we always face one common problem: lack of output lines. I’m known that you will need another micro-controller for overcome this matter.

However, the designer of ‘508A have created a 5 output links in an 8-pin chips and this truly awesome!

Let’s see how we can benefit from this innovation.

1. LED and Piezo on One Line

This is one of the simplest combinations.


2. LED and Push Button on One Line

Add a secret reset button across the LED.

3.Different Programs in Chips

Five programs combined to reduce cost.

4. Line Reversal

Create a voltage reversal.

5. Driving LED’s

For drive the LED from an output.

6. Driving LED’s in Parallel and Series

Choose to either drive LED’s in Parallel or Series.

7. Driving more than 4 LED’s

Drive up to 4 LED’s in one time.

8. Connecting a Globe

Easily control the dimness of globe.

9. Connecting a Relay

Handle the operation of relay.

10. Creating Security Wiring For an Alarm

Enable a diode for security warning purpose.

11. Connecting a Motor

Control the motor in forward/reverse with transistor.
