Basic Minimum System Microcontroller ATMega8535 Circuit Diagram with SRF04 Sensor and LCD Input Output

Robotronicdiagram. - In the first article of microcontroller AVR circuit schematic diagram, we want show you one of basic minimum system microcontroller ATMega8535 circuit diagram that connected with ultrasonic sensor SRF04 as input and then connected with LCD 2x16.

With this circuit diagram like in figure 1 below, we think you can implemented to design distance measurement, high measurement, and other implementation. You only need ability to program this microcontroller to implement this circuit schematic.

Circuit Diagram

Figure 1. Basic Minimum System Microcontroller ATMega8535 Circuit Diagram

Component 
  1. IC ATMega8535
  2. X-Tal 16 MHz
  3. R1 4K7
  4. C1 10nF
  5. C2, C3 22 pF

Description

Circuit diagram like in figure 1 above is Basic Minimum System Microcontroller ATMega8535 Circuit Diagram with SRF04 Sensor and LCD Input Output. In this description, we will try describe that this circuit diagram implement to design human high measurement device.
  1. In the design of this system, that microcontroller part of VCC pin (30), AREF (32), and VCC (10) will receive a voltage / DC current from the power supply for 5 volt, and feet / GND pin (11,13) energized ground . 
  2. Furthermore, the port B0 and B1 will connect to port leg of the SRF04 ultrasonic sensor. 
  3. Port is connected to pin B0 SRF04 ultrasonic sensors on the TRIG pin, and pin port B1 is connected to ECHO. 
  4. X-TAL2 and X-TAL1 functions as a series of system clock, using the component by the two 22pF capacitors and a single 16MHz ceramics. 
  5. Port PC0, PC2, PC4, PC5, PC6, PC7 associated with LCD 16X2 as the output display.
And in here we also will give you form of PCB design layout of Basic Minimum System Microcontroller ATMega8535 Circuit Diagram with SRF04 Sensor and LCD Input Output from figure 1 above. And the PCB layout of this circuit diagram like in figure 2 and 3 below:
