RC Robot Tank
I produced a remote controlled robot tank that utilizes an Arduino UNO. The robot tank consist of two DC motors and can be operated by a wireless PS2 controller

For my first milestone of my main project, the RC robot tank, I constructed the chassis of the robot as well as made my gears turn on using the Arduino. I started off building the chassis of the tank which included the gearbox, the universal plate, and the track and wheel set. I started building my gearbox which included two DC motors, gears, and two shafts. Then, I used the dremel to drill two holes in the universal plate to attach my gearbox. Then I connected one wheel to each of the shafts which made sure the rest of the wheels were turning. After building the chassis of my robot, I started to connect my Arduino to the L198N motor driver. After wiring the Arduino and motor driver together, I soldered the wires to connect the motor driver with the motors. Then I tested my motors through a simple code to make sure the motors would run. After all the uploading my code to the Arduino, I connected my 6V battery to the Arduino which activated the motors. Although my project ended up working, I had many challenges along the way. My first challenge was that I did not use the wire strippers to expose the copper which resulted the electricity flow to stop. My second problem was that I connected my 6V batteries to the 3.3V slot which fried my Arduino and computer.
For my starter project, I chose to build the Simon Says game. I picked the Simon Says game because it would introduce me into soldering as well as learn different electrical components to the machine. There are two switches on the Simon Says game. One to power the device on and one to activate the sound. The machine is powered by two 1.5V alkaline batteries which can power the lights and the noise. On the bottom of the board, there is a microcontroller, which is the control system of the whole device. The microcontroller contains processor core, memory, and programmable peripherals. There is also a black cylinder called a piezoelectric buzzer. The piezo buzzer makes sounds when voltage enters, causing crystal or ceramic form of the piezoelectric element to deform. There are also two decoupling capacitors which filter out the AC signal from the DC signal, creating a purer DC signal. Another component that my machine had was the 10K resistor. The resistor’s job is to reduce current flow as well as lower the voltage. I have learned a lot through this project such as soldering and also knowing what the components such as decoupling capacitor, microcontroller, and the piezo buzzer does. I took a long time to research the parts of this device as I have not used many of those parts.
