• #ANODE CATHODE PIC HOW TO#

Now suppose we want to display 0, then we need to glow all the LEDs except LED which belongs to line “g” (see diagram above), so pins 2.0 to 2.6 should be at 0 (should be 0 to TURN ON the LED as per negative logic) and pin 2.7 and 2.8 should be at 1 (should be 1 to TURN OFF the LED as per negative logic). You should also read this article to understand the basic connection of microcontroller like crystal and reset circuitry.Īs shown above the circuit diagram for interfacing 7 segment display with 8051 microcontroller, we have connected a,b,c,d,e,f,g,h to pins 2.0 to 2.7 means we are connecting 7 segment to port 2 of microcontroller. You can understand this negative logic concept in this article “ LED Interfacing with 8051 Microcontroller”. As we know that microcontroller doesn’t provide enough power to glow the LED so we need to connect LED’s cathode to microcontroller pin and LED’s anode to power supply. Here we are using common anode type of 7 segment because we need to connect LEDs in reverse. And all the negative thermals are left alone. And all the positive terminals are left alone.Ĭommon Cathode: In this all the positive terminals (Anodes) of all the 8 LEDs are connected together, named as COM. There are two types of 7 segment displays: Common Anode and Common Cathode:Ĭommon Anode: In this all the Negative terminals (cathode) of all the 8 LEDs are connected together (see diagram below), named as COM. These common anode/cathode are internally shorted so we need to connect only one COM pin. There are 10 pins, in which 8 pins are used to refer a,b,c,d,e,f,g and h/dp, the two middle pins are common anode/cathode of all he LEDs. We can refer each line/segment "a,b,c,d,e,f,g" and for dot character we will use "h". We can refer each segment as a LINE, as we can see there are 7 lines in the unit, which are used to display a number/character. It just consists 8 LEDs, each LED used to illuminate one segment of unit and the 8 th LED used to illuminate DOT in 7 segment display. It’s the simplest unit to display numbers and characters. We are using AT89S52 microcontroller from 8051 series.īefore interfacing, we should learn about 7 segment display.

In this tutorial, we are going to learn how to interface a 7 segment display with 8051 microcontroller. It can also display some character alphabets like A,B,C,H,F,E etc. The structure of hard carbon can be manipulated through the process of hydrothermal carbonisation and pyrolysis, the methods used to synthesise it.Seven segment displays are important display units in Electronics and widely used to display numbers from 0 to 9. What sets hard carbon apart from other anode materials, such as the commonly used graphite, is its structural versatility. Anodes, a key component of batteries, are where the ions are stored before they travel through the electrolyte to the cathode, producing an electric current. Its high ion storage capacity makes it an attractive candidate for the anodes in battery systems. Hard carbon, as its name suggests, is a form of carbon that is structurally denser than other forms. Unlocking the potential of hard carbon anodesĪt the heart of the research is a deep exploration of hard carbon, a material rich in promise for future battery systems. Hard carbon’s potential advantages, including sustainability, high capacity, high power density, and long-term stability, position it as a promising candidate for advancing next-generation battery technologies.

Lower-temperature synthesized hard carbon (G1000) excels in lithium-ion batteries due to its high surface area and defect-rich structure, while G1500 demonstrates superior performance in sodium-ion batteries, offering a balance of defects, interlayer spacing, and porosity.The use of hard carbon anodes in sodium-ion, lithium-ion, and potassium-ion batteries, revealing structural variations that impact their electrochemical performance.
