Project ideas using Arduino: 3 New Ideas for June 2021

This article presents three new project ideas using Arduino on custom PCB boards. With its simple and accessible user experience, most hobbyists and students prefer Arduino over other microcontrollers. Despite its many advantages, the Arduino board is relatively inexpensive as compared to other microcontrollers. Hence, a worldwide community shares their project ideas using an Arduino. So, without wasting much time, let’s look at some of the best project ideas using Arduino.

Hand gesture controlled arm

It is one of the best project ideas developed using the Arduino Pro Mini microcontroller. With this, you can remotely control any appliance without even touching it. Isn’t it amazing? The robotic hand mimics all the actions that you perform with your hand. So, how does it happen?
So all it requires is a sensor, a transmitter, and a receiver. The ADXL335 accelerometer works as a sensor and monitors the movement of your hands. It converts the gestures into corresponding values. A transmitter then sends these values to a receiver using the nRF24L01 module. The receiver compares it with the reference and executes the predefined function.

Components Required

Self-locking On/Off Switch
Capacitors
Resistors
LED
3.7 LiPo battery
nRF24L01 module
ADXL335 accelerometer

PCB details

The copper traces on a PCB ensures uniform signal quality. Despite the small size of the PCB, the temperature of the board remains optimum. With a HASL surface finish, the PCB looks spectacular, which is visible in the image below.

The smartphones have a unique feature to Auto-adjust the brightness. A sensor on the top detects the surrounding light and then adjusts the screen brightness according to it. But, as we know, most laptops lack this unique feature, and hence, we have to vary the brightness manually. It is not a big issue, but sometimes it becomes irritating. Right? So, if you are also looking for a solution, then we got one for you. Follow this simple project and make an Auto-brightness adjuster using an LDR and an Arduino. Place the sensor on the top of the screen, execute the code, and see the magic it will do.

Components Required

LDR x2
10K resistor x1
PCB board from PCBWay
Arduino Pro Micro

PCB details

It is a double-layer PCB with 70.5x36mm dimensions. The two projected heads on the PCB hold the LDR and detect the variation of light. The matte-black solder mask over the surface of PCB protects it from oxidation and gives it a classy look. The image here shows the software design of the PCB.

Are you a fan of Wolverine? Do you also get amazed when the claws come out of Hugh Jackman’s hands? No wonder every Wolverine fan admires those claws in their hands too. Well, we can’t provide you the actual adamantium claws, but we have a fantastic project that lets you control 3-D printed Claws using your muscles. While looking for project ideas using Arduino, these types of projects are hard to find. So, how does it work?
A muscle sensor continuously monitors the muscle movements and converts them into values. So, when the arm flexes, the servo motor operates by projecting the claws outward. As the arm relaxes, the servo motor reverses its direction and places the Claws back in the case. So, in this way, your arm becomes similar to Wolverine’s arm.

Components Required

3D printed case
Servo motor
SPST switch
Arduino Nano
LiPo battery
Resistors
Capacitors

PCB details

The small-sized PCB board from PCBWay works as the heart of the project. The board is uniform with no breaks and solder joint repairs. The drill holes, tracks, and vias are all within prescribed standard limits. The image here shows the software design of the PCB.
