ESP8266 Remote Relay
Reboot Oct 23,2022
This pcb has a WeMOS D1 Mini with ESP8266 to control the on board relay.Control of the relay can occur wirelessly, and the ESP8266 UART pins are also available on a header to optionally allow an external RS485 or bluetooth module to be used.The Github project uses ESP-NOW to communicate between this relay control board and another ESP8266 board that uses a current transformer: https://www.pcbway.com/project/shareproject/SCT013_Current_Monitor_for_ESP8266_cc7ccd2e.htmlWhen the current transformer...

Arduino hearing test device - Audiometer
Pavleski Oct 22,2022
  An audiometer is a machine used for evaluating hearing acuity. They usually consist of an embedded hardware unit connected to a pair of headphones and a test subject feedback button. This device typically transmits pure tones to the headphones of the test subject at varying frequencies and intensities, and records the subject's responses to produce an audiogram of threshold sensitivity.I recently took a hearing test in a professional facility, and I received the results in the form o...

PCB Candle that glows forever- KINDA
Arnov sharma Oct 22,2022
Hey everyone how you doing!So this is an EVER GLOWING CANDLE PCB that will glow forever and never run out of wax because it's not made out of wax.However, it will stop glowing after a month of constant blinking when the battery runs out.The Idea here was to make an awesome and safe night light-decorative light for my desk, Aroma candles, and other decorative candles look great but they are dangerous to keep around, the fire hazard is one of the problems that can cause because of Candle...

SP0256 AL2 Speech synthesiser with serial I/O for Arduino/PIC etc.
PureZX Oct 20,2022
OverviewThe SP0256 AL2 is an Allophone speech synthesiser by GI (General Instrument). It was widely used in the 80s and 90s in speech synthesisers for virtually all the 8-bit computers. The chip can produce 64 allophones including several pauses of various lengths, and with these sounds you can build recognisable human speech.How to use itThe board has 9 connections on a single 0.1in header. Connect +5v and GND as marked on the PCB. SP+ & SP- are 8R speaker connections. On powering up take t...

How to make an alarm clock with pic microcontroller
electronicguru0007 Oct 17,2022
he five push buttons will act as an input for setting the alarm for the required time. So one end of all the push buttons are connected to ground and the other ends are connected to PORTB pin, internal pull-up resistor will be used on these pins to avoid the pins floating. The Buzzer will act as an output and will give us a beep when the alarm gets triggered and is connected to the PORT S pin. The current time is always kept in track by the DS3231 RTC module from which the PIC receives...

How to make RMS to DC Converter using IC AD736
electronicguru0007 Oct 17,2022
A True-RMS or TRMS is a type of converter which converts RMS value to equivalent DC value. Here in this tutorial, we will learn about true RMS to DC converter, how it works and how measurement methods can affect displayed results.The IC AD736 has few functional subsections like the input amplifier, full-wave rectifier (FWR), RMS core, output amplifier, and bias section. The Input amplifier is constructed with MOSFETs, so it is responsible for the high impedance of this IC.After the input am...
