When camping, If someone or a creature is approaching to your tent, The arlarm will works to wake you up or remind you and scare them away.
In this Visuino tutorial, we’ll build a fun project using an Arduino, a buzzer with red LED module, and a 4x1 membrane keypad.
You will play the song twinkle twinkle little star using a buzzer and get to know about Swift language.
This is project is designed to let you know when you have reached the optimal level of water for your pre-workout!
The gamer needs to decide whether the frequency of the light (the intensity) is as same as the frequency of the buzz (the pitch).
A system that scans around and alert in case of an object at a close proximity.
You will learn about the buzzer, try to rotate a potentiometer to change the sound and get some basic knowledge of Swift language.
A "singing" piezo buzzer that changes pitch according to a potentiometer and a tilt switch.
Using PWM to output sound wave with a different frequency, so as to play music with the buzzer
This little project makes a keyboard with 4 tones and a LED that comes on for each tone.
When the temperature is above a certain limit it will on the buzzer and LED and at the same time it will post an alert message in telegram.
Tick tock
It is a thermometer that warns when the temperature is above 23 degrees Celsius, and if it is lower, it shows a green light.
Who says Santa only visits in December? 🎅 Join the hilarity as I dive into the springtime spirit with some seriously tardy Santa PCBs
Vaughn Johnson UCF-Spring 2023-DIG3602C-Davis Project 06
A system which connects the Raspberry Pi to the Arduino Nano 33 IoT via an MQTT service and allows communication between the two.
Detect motion with a PIR sensor, trigger a buzzer, and monitor the status remotely using NodeMCU and KiwisIoT.
