Hello everyone, I am here with you having finished my scrolling text that I have been working on for a long time. First of all, the circuit has 60 columns and was made using 5×7 dotmatrix. The printed circuit of the circuit belongs entirely to me. The program part belongs to our friend Logan, whom everyone knows.
The circuit is made on a single-sided plate and there are jumps. I made the dotmatrix and driver parts on separate plates, it was very nice, this is my first pic-controlled scrolling text circuit, I am constantly trying to improve it. The simulation file in the attachment and the project are different because we get an error when driving uln2803 with Isiste cd4514, instead I decided to simulate it with 74154, which works with exactly the same logic, as you know, the 4514 integrated circuit is the inverted version of the 74154 integrated circuit, and in this way, we achieved more brightness in dotmatrixes by driving with uln

Level indicator with LCD VU Meter PIC16F877
PIC16F877 circuits with a suitable title was 2 × 16 LCD display VU Meter circuit with a simple voltmeter or can the system prepared with almost the same software PicBasic lcd, pic and a few passive components in the circuit board.
Analog level indicators have been suffering for some time the logical offset of the scene has imposed technological advancement. The need to interpret in a scale position indicator of a required time and work that was replaced by colorful digital displays presenting the exact numbering of the value we are trying to assess all. However, there are applications that do not demand to know an exact value but have an estimated incidence of “how much” information. Clear examples of this are the meters that mentioned audio level indicators signal reception and all the indication involving a dynamic measurement of any magnitude.
