WEEK 5
Schematic Diagram
On week 5, I started focus on schematic diagram to
understand the flow of the project. Schematic diagram is the part that will
explain about constructed the circuit. It divided into two part, which is on
robotic arm and hand controller.

| Schematic Diagram for Robotic Arm |
Based on the figure,
ATMEGA328P is a main of the components because it will control the entire
component with the program. This project use two DC motor to move the robotic
arm for this project and the Arduino used to transfer the program’s code to
ATMEGA328P. This
project also use RF module that is comprises of an RF transmitter and an RF receiver. The transmitter/receiver (Tx/Rx) pair
operates at a frequency of 434 MHz and An RF transmitter
receives serial data and transmits it wirelessly via its pin4-connected antenna
using RF. HT-12D is decoder IC which is it divided to encoder and decoder.

| Schematic Diagram for Hand Controller |
The schematic diagram for hand
controller that is the controller will receive the hand’s direction from user
and send the signal data to the robotic arm’s program. The program has motion sensor
accelerometer; the sensor accelerometer can used to measure the sensor
acceleration. when receive the movement up, down, left, or right from the user,
the data will be send to ATMEGA328P. The ATMEGA328P will send the
instruction data to RF module transmitter for the next process to send the data
at Robotic arms program. The RF transmitter module is a small PCB that is
capable of transmitting a radio wave and modulating the radio wave for data
transmission. Usually, these
transmitters are subject to control requirements that command the maximum
acceptable transmitter power o / p, band edge, and harmonics. This program use
12v battery and will put on the glove, easy for user. After doing the schematic, i started doing program for my project by using Arduino software on my laptop.
