Hello, I am a new registered member ( from Belgium). In the past,I was a reader of the forum but no active user.
Now I would to ask your help because I have some problems. I want to switch 16 relays in a pattern. First, I would like to switch relay 1 and display this on an LCD. Then with a push on a button I want to switch relay 2 and display this. Then relay 3. Below I have posted a code but this does not work properly. Can someone modify the code ( for example shifting relay 1 to 7)?
A Brief Note 74HC595 Shift Register IC. As mentioned earlier, the 74HC595 IC is an 8-bit Serial IN Parallel OUT shift register. It is 16-pin IC available in a wide range of packages like DIP, SOIC, SSOP and TSSOP. Pin Diagram of 74HC595 Shift Register. The following image shows the Pin Diagram of 74HC595 Shift Register. Jul 25, 2018 - When you have pin limitation but you need to use LCD then this code can be used to interface LCD with shift register. The main code is written.
How can i send multiple relays together. What is the rule or code therefor? For example, what is the code when i want to switch relay 2 and 8 together?
I use a Arduino UNO with a dual shift register (2x74HC595). The outputs of the 2 shift register are connected with a ULN2803 (2X).
The outputs of the ULN2803 are connected with the relays. Thanks in advance.
Introduction HD44780 based character LCDs require at least 6 I/O lines from microcontroller to display data. Therefore, they are not suitable for low-pin microcontrollers like PIC12F series microchips.

In this project, I am going to show how to drive an HD44780 based LCD display with only 3 pins of a microcontroller. I am going to demonstrate it with PIC12F683 microchip.
The character data and command from the microcontroller is transferred serially to a shift register (74HC595), and the parallel output from the shift register is fed to LCD pins. About 74HC595 74HC595 is a high-speed 8-bit serial in, serial or parallel-out shift register with a storage register and 3-state outputs. The shift register and storage registers have separate clocks, SH_CP and ST_CP respectively. Data in the shift register is shifted on the positive-going transitions of SH_CP, and the content of shift register will be transferred to the storage register on a positive-going transition of the ST_CP.
If we tie both the clocks together, the shift register will always be one clock ahead of the storage register. The 8-bit data of the storage register will appear at the parallel output (Q0-Q7) when the output enable (OE) is low. In this project, SH_CP and ST_CP are tied together. So, if we want to receive a serially transferred 8-bit into parallel form at Q0-Q7, an extra clock pulse is required after transmitting the 8-th bit of serial data because the clocks are tied and the storage register is 1-clock behind the shift register. HD44780-based character LCD All HD44780 based character LCD displays are connected using 14 wires: 8 data lines (D0-D7), 3 control lines (RS, E, R/W), and three power lines (Vdd, Vss, Vee). Some LCDs may have LED backlight and so they may have additional connections (usually two: LED+ and LED-).
