Mini Arduino with ATTINY85
silicioslab Mar 18,2022
Do you know the ATTINY85 microcontroller? This article has news and a gift for you. Many people develop projects with few digital inputs/outputs and use the ATMEGA328P microcontroller. But there is a problem: it is expensive, there are many digital pins left, your circuit will be complex and the project board will take up more space.Today I want to show you a simpler yet powerful solution. I want to introduce you to the ATTINY85 Microcontroller. It is a compact, simple, low cost and low power co...

Classic Analog Spectrum Analyzer for Your Desktop
Donners Mar 16,2022
This is a spectrum analyzer that visualizes 10 audio frequency bands. Although it might look like just another FFT ESP32 project, it is most certainly not! This design uses a PCB that I designed and build and although it involves an ESP32, it doesn't involve FFT. ( A digital way to determine what frequencies are embedded in a signal). The analysis of the input signal is actually done by 10 good old fashion opamp driven, band filters.An ESP32 is used to host a webserver for visualization and to d...

A custom ATmega32u4 board
Curious Scientist Mar 15,2022
I decided to make my own ATmega32u4-based microcontroller board for several reasons. I wanted to have a general design based on this microcontroller which I can adapt in other PCB designs that need a microcontroller. I also wanted to practice SMD soldering, PCB design in general, and I needed some new microcontrollers so this was kind of a win-win situation.I added an interactive BOM so you can pick the parts more easily.Parts Value and footprintC5, C7, C10 - 100nF C_0603_1608MetricC2, C6 - 10uF...

DIY Pulse Oximeter
Shinganapure Mar 12,2022
Step 1: Basic PrincipleHow An Oximeter works?Basically Oximeter calculates the percentage oxygen saturation in the blood on basis of amount of different light absorb in it. Oximeter has One photodiode and two LEDs one is Red LED & another one is InfraRed LED, both LEDs are switched one by one on a certain frequency. To take measurements fingertip is placed in between of photodiode and LEDs as shown in the picture. Oxygenated blood absorbs more Infrared Light and passthrough the more red ligh...
