One digit up and down counter using 74LS192/CD40192 and RF remote control

This is a simple up and down counter that can be operated by a four-channel RF remote.

The 74LS192 or CD40192 up and down counter chip is used in this gadget. The 74LS192 chip is triggered by a NE555 (set in monostable mode). The CD4511 chip controls the seven-segment display.
