The Dice Game on 6802 Nano computer

SB-Projects - San Bergmans

A pair of dice is the first small example application I present here. The interface is nothing more than 2 sets of 7 LED's, arranged in the form of two dice. One push button per die completes the interface circuit

Wide-Bandwidth Dual JFET Opamp LF353

These devices are low cost, high speed, dual JFET input operational amplifiers with an internally trimmed input offset voltage.

They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents.
