In this article, we are going to make an Arduino weather clock which will tell us the time, date and temperature.
This is the 2nd tutorial on my ESP32 learning journey. Here, an OLED shows time and captured data by DHT sensor (temperature & humidity).
How about a metronome that beeps and lights up? Why I think yes! Also same setup with separate code runs a Whack A Mole game!
Remember the days when you would sit listening to WWV time signals on your shortwave radio (tick, tick, tick…At the tone, the time will be…)
A thermostat with an OLED capable of plugging into a USB port.
A digital thermometer built from scratch using Attiny85 and ds18b20 temperature sensor, which can run on a CR2032 over 130 days!
Use to record somebody's blow strength. Since without calibration it is relative value.
