Machine Design

Introduction
The assignment for the week was to
Design a machine (mechanism + actuation + automation) build the mechanical parts and operate it manually. Actuate and automate your machine. Document the group project and your individual contribution. For this assignment we decided to build to build a conveying belt with item counter

CONTRIBUTION LIST
  1. BRAMWEL OLELA - FABRICATION and DOCCUMENTATION
  2. DERICK WERE - EMBEDDED SYSTEMS PROGRAMMING
  3. KIOKO MUTHUI - ELECTRIC CIRCUIT
  4. CEDRIC DIUR - ASSEMBLY
Materials
  1. Caton
  2. glue stic
  3. bottle tops
  4. scissor
  5. straw
  6. sticks
  7. Hardware used
  8. Geared Mortor
  9. Bench power supply
Objective

Count specific amount of item by moving them to a specific collection point, if count achieved stop conveyor belt.

Electric schematic

I was incharge of creating the electric design and schematic. I decided to try out tinker CAD for this project compaired to Eagle which i am quite used to, this wasessential so as to provide other members of the team with a graphical layout of the circuit.
The Component List for the electrical circuit is as follows

  1. DC Motor
  2. LDR
  3. Diode 1N4001
  4. Transistor pnp TP130
  5. LED
  6. 10k Resistor
  7. 1K resistor
  8. Arduino UNO
  9. Bench power supply

The first step was selecting all the components needed nand inserting them in the work area one by one

The next step involved joining the components one by one and colour coding the connections to avoid confusion. I later uploaded the code developed and simulated the circuit
