decoder

I had use 433 Mhz RF module with transmitter (FS1000A) and receiver (MX-RM-5V). Interfacing with Encoder (HT12E) and decoder (HT12D) respectively. The problem is that I am using two sets of these set up in circuit one and two. Which means the first circuit having encoder with the same address as...

I've been designing a simple random number generator that is supposed to generate a number from 1-100 and display it using three 7-segment displays(D0, D1, D2). This design also uses a 555 timer(astable 1400Hz) and two BCD decade counters. For D0 and D1, I am using CD74HC4511E decoders, which...
