(Buzzer Pin must be a PWM Pin)A Switch is also there between CR2032 and Attiny85.After Finalizing the Schematic, I move on to the designing part of the board.I first searched for R2D2 2D Image on google and selected this one, it was minimal and will look good even after converting into Black and white BMP.I had to convert this images into a BMP image as my OrCad PCB Suite only imports Images from BMP format.After converting the image, I imported it as a silkscreen TOP layer and prepared the board around this image.I put the Attiny85 and LEDs on the TOP side and added the remaining THT Components from the BOTTOM Side.I also added a few solder mask openings on the copper layer and on FR4 to increase the aesthetics of the board. 4.So here's something special, A Mini R2D2 PCB that speaks ASTROMECH.Astromech is a fictional language in the star wars franchise consisting of whistles and beeps.This Mini R2D2 that I made is a Keychain.Its brain is an Attiny85 and is powered by a CR2032 Coin Cell holder.I was inspired by this Instructables- made a simple Arduino Uno setup that produces random beeps every 3 seconds.I took the concept and prepare the whole thing by using an Attiny85 with a standalone circuit instead of using a whole Arduino UNO.Attiny85 SetupBefore getting started, I prepared a simple Attiny85 Setup that consist of an Attiny Connected with a Buzzer and one LED.I followed the below schematic for connection and made a Breadboard edition first.I programmed the attiny85 with my Arduino as ISP Programmer just by putting the attiny85 onto the IC Socket and flashing the MCU.PCB DesignAfter finalizing the breadboard edition, I started making a schematic in my PCB Designing suite which was this-The Schematic consists of an Attiny85 connected with a CR2032 Cell, Two LEDs are connected in parallel are attached with Pin D2 and a Buzzer is added to Pin D0.
4 bit parallel to serial converter serial#
Describe the steps involved in operating the serial-to-parallel converter - through use of the selector bits for serial data bits in and the parallel out. What would happen if the parallel-to-serial converter was not recirculating? 3. Describe the steps involved in operating the parallel-to-serial converter - through use of the selector bits for parallel load and serial output. Include wiring diagrams and screen shots for each of the circuits built. Lab Report Conclusions: Write a separate conclusion for each part of the lab. Operate the circuit as a ring shift counter, and demonstrate it to the instructor. Use a switch or button for the clock, a switch for the serial input bits, and an LED for each output bit. Draw a wiring diagram to connect a 74194 IC as a 4-bit serial-to-parallel converter (use either shift right or shift left). Part B: 4-bit Serial-to-Parallel Converter - Use Multisim or Verilog 1. Build and test the circuit, and demonstrate the operation to the instructor. Use a switch or button for the clock, an LED for the serial output bit, an LED for the clock pulse, and switches for the mode control and the 4-bit parallel inputs. Either shift right or shift left may be used. Draw a wiring diagram to connect a 74194 4-bit Bidirectional Universal Shift Register IC as a 4-bit recirculating parallel-to-serial converter. Transcribed image text: Lab 4.1 - Serial & Parallel Conversion, Buffers Part A: 4-bit Parallel-to-Serial Converter - Use Multisim or Verilog 1.
