74LS192 and RF remote control operated one digit up down counter

This is a simple up and down counter that can be operated using a four-channel RF remote. The 74LS192/CD40192 counter chip is used in this gadget. The 74LS192/CD40192 chip is triggered by a NE555 (in monostable mode). The 4511 chip controls a seven-segment display.
