6 Easy Arduino Projects For Beginner Coders

Probably one of many coolest Arduino projects out there’s a remote-controlled automotive, however they’re additionally one of the daunting initiatives for learners to undertake. However, you will be glad to know that there are RC automotive variations that do not require being a coding skilled.

This Bluetooth-controlled car could appear too formidable for a newbie mission at first look, however it’s really a straightforward construct. It’s run by an Arduino UNO board, and contains a number of key elements: 4 gear motors with wheels for transferring the automotive, 4 LEDs for signaling the lively standing of every motor, a motor driver for working all of the motors, a Bluetooth module for distant management, and a battery for powering the automotive. 

Upon powering up, the automotive routinely turns into seen to exterior Bluetooth gadgets like your telephone. You can then join it to your system utilizing the project developer’s Android app, and begin controlling the automotive with the joystick. Press one course, and the motors for that individual course shall be activated. The LEDs linked to these motors will even gentle as much as present which of them are in motion.

Unlike the opposite initiatives on this checklist, the code for this setup is a bit over 100 traces, however it’s a superb introduction to working with customized capabilities that may be known as inside different capabilities, just like the loop operate. You typically would not want to change something within the code, besides maybe to vary the pin configuration of the motors in the event that they occur to run reverse to your command.

The Challenges and Drawbacks of Lithium Batteries

In an article from Air Quality News, Beatrice Browning, a Ph.D. researcher at the Faraday Institution, explains that the lifetime of a battery can be reduced when the structure of its electrodes is damaged. This damage is caused by the cycling of lithium ions in and out of the electrodes. A study by the Royal Society of Chemistry identifies three main external factors that contribute to the degradation of lithium-ion batteries: temperature, state of charge (SoC), and load profile. Over time, lithium-ion batteries naturally lose capacity due to a limited number of lifecycles. Battery University suggests that counting cycles is inconclusive as discharge depth can vary, and there is no specific standard for defining a cycle.

In addition, certain applications of lithium-ion batteries, such as electric vehicles (EVs), are influenced by external factors that affect their overall lifespan. These factors include charging rates, weather conditions, and charging practices, as reported by SlashGear. Even without any use, lithium-ion batteries can age and degrade through continuous discharge, as confirmed by Newark Electronics. Furthermore, lithium batteries may experience degradation due to manufacturing defects, which could potentially have serious consequences.
