![]() ![]() With a relay, you can easily use an Arduino to control the power of nearly any type of electrical device. Here is a simple street light controller with a switching circuit that overcomes the problems of false triggering and no switching capability. Jumper wires A/C power cord Light socket LED (optional) 330 Ohm resistor (optional) But first, let’s review some concepts Relays Relays are electromechanical devices used to control power for the attached devices. This project is available at Street Light Controller 41. Here is a simple street light controller with a switching circuit that overcomes these problems. Two of the problems commonly associated with street lights are false triggering due to slight variations in the intensity of ambient light and no control over switching action. This project is available at USB MP3 Player 40. The module comes with a remote for your convenience… In this article, you will find instructions to assemble a USB MP3 module and make a USB MP3 player. ![]() This project is available at Multimeter Test Leads from Scratch 39. These homemade test leads are low-cost and easy to use. Multimeter Test Leads from Scratchīuild your own multimeter test leads from material available in the market. This project is available at How To Make A Business Card Flashlight 38. The essence of this project is that anyone can make it at home without any soldering or PCB. ![]() Here we make a business card useful and unique by turning it into a business card flashlight. This project is available at Smart Battery protector 37. Built around a PIC microcontroller, this is just something we would all love in competitions as well. This one would be the one for students to design and implement in college competitions. This mini project is available at Hand Video Game 26. Let’s get to designing the once-popular game using electronics. This next project is a throwback to the time when we enjoyed it. This mini project is available at Simple Line-Following Robot 25. It lays the foundation for building your own behavior-based (simulated) robot. It is a simple project, which can be taken up as a classroom assignment. This robot follows a color with the help of sensors. while supporting lithium battery charging Materials: XIAO ESP32C3 2, Grove - Button 1,Grove - Relay 1. ![]() It can be used to switch ON or OFF a device after a particular period of time set by the user. Arduino Countdown Timer With Relay Made by Ron / Clocks / Garden / Home Automation / Lights / Sensors About the project In this tutorial we will learn how to make a Countdown Timer, you can set time When timer reaches the zero the Relay will trigger the light. Copy and paste the code below into Arduino IDE. This mini project is available at Sixth-Sense Media Player 24. 32 Timer switch with Relay and LCD Arduino code A timer switch is an electrical switch that is operated by means of a timer circuit or timer mechanism that measures specific time intervals. It requires Windows Media Player, LabVIEW, Arduino, and an accelerometer. This project explains how to control the media player using a hand glove. This mini project is available at Water Pump Controller 23. The purpose of this circuit is to create a new topology with a good power factor maintained at AC voltage input, to provide good efficiency output to the battery, and to increase its life. This Stereo Amplifier Is Simple To Make.The 3V3 pin is the output from the on-board voltage regulator you can get up to 600mA from it. The VIN pin can be used to directly power the ESP32 and its peripherals, if you have a regulated 5V power supply. There are two power pins: the VIN pin and the 3V3 pin. The strapping pins function normally after reset release, but they should still be used with caution. However, if peripherals are connected to these pins, you may encounter issues when attempting to upload new code or flash the ESP32 with new firmware, as these peripherals prevent the ESP32 from entering the correct mode. On most development boards with built-in USB/Serial, you don’t need to worry about the state of these pins, as the board puts them in the correct state for flashing or boot mode. Depending on the state of these pins, the ESP32 will enter BOOT mode or FLASH mode at power on. These pins are used to put the ESP32 into BOOT mode (to run the program stored in the flash memory) or FLASH mode (to upload the program to the flash memory). ![]()
