LC meter of using the franclin oscillator アルディーノマイコンを使ったLCメーター
Asai Nov 14,2022
This LC meter is majorly composed by 74HCU04 Franclin oscillator and Arduino frequency counter.The east German engineer of Dr.Hegewald had published this LC meter design principal. AADE and some suppliers introduced the products for HAMs. At the original design they used PIC. (Such information is kept on VK3BHR web site"https://sites.google.com/site/vk3bhr/home/lcm1/faq?pli=1")I followed this method by using Arduino to recognize the principal of L or C measuring.I had posted my sketch on GITHUB(...

Mini DIY H-Bridge made from Fets
Arnov sharma Nov 14,2022
Hey, what's up, everyone? So here's something small and interesting.A Mini H-bridge board that can power any DC motor and switch its polarity by using two GPIOs from a microcontrollerBy using this small 20mm x 20mm board, we can power small DC motors that operate at a lower voltage, like below 5V, from a single Li-ion cell.This driver can be used in projects that require less space to work with; for example, I prepared a mini-rotating table for capturing rotational videos of components...

Arduino Whistle Detector Switch using Sound Sensor
Nov 14,2022
As a kid I was fascinated by a toy music car which gets triggered when you clap your hands, and then as I grew up I wondered if we can use the same to toggle lights and fans in our home. It would be cool to just turn on my Fans and lights by just clapping hands instead of walking my lazy self to the switch board. But often times it would malfunction as this circuit will respond to any loud noise in the environment, like a loud radio or for my neighbor’s lawn mower. Although building a clap switc...
