Environmental monitoring and logging with RTC, DHT22 and 4-digit 7-segment display
Overview The aim of this project was to build an environmental monitoring system for logging temperature and humidity. A display shows the actual temperature and humdity, while both values are stored on a sd card each five minutes with a time stamp. Components Wiring The DHT22 sensor with 10k resistor pull-up. Coding Run the code…
Raspberry Pi NewTron WLAN radio with touchscreen
Overview The aim of this project was to build a simple wlan radio with touchscreen to listen to german radio stations (i.e. Fritz Radio from Berlin). Components Touchscreen and enclosure were ordered from itontec at amazon: http://www.amazon.de/dp/B00OFLKPG4/ref=cm_sw_em_r_mt_dp_NfFmxb14ASH31 Install the touchscreen On the components image above you can see which pins are used for the diplay and how you…
Simple Arduino GPS clock with OLED 128×32 I2C
Overview A simple GPS clock with a 9V battery power supply and a small OLED display was built. It only shows time, date, position and speed. When the system is off, time is kept, since a back up battery is installed on the backside of the gps module. Components Arduino nano GPS breakout board 128×32 OLED…
Bubble display clock
Overview The aim of this project was to build a simple clock with a tiny bubble display that sparkfun.com started selling. Furthermore, a magnifying glass was built in a box to produce a magnifying image of the tiny bubble display. Components Arduino nano Bubble display QDSP6064 https://www.sparkfun.com/products/retired/12710 RTC DS3231 magnifying glass f = 30mm and d…
Arduino clock with 128×64 I2C OLED display, RTC DS3231 and automatic DST
Overview A simple OLED clock with power button and switch button was constructed. No time adjustments are required, since the clock provides automatic DST. Components Arduino nano Adafruit OLED 128×64 RTC DS3231 Hammond 1591 plastic enclosure http://uk.rs-online.com/web/p/general-purpose-enclosures/4935994/ Push button https://www.sparkfun.com/products/11967 Power button https://www.amazon.es/Interruptor-ON-OFF-de-palanca/dp/B00L7Z6QKU/ref=sr_1_82?ie=UTF8&qid=1461922458&sr=8-82&keywords=bricogeek Wiring Coding You will want to run the sketch twice, once to set the clock,…
Arduino clock with 4-digit 7-segment display and RTC DS3231
Overview A simple clock with a 4-digit display and a switch button to switch between time, date and room temperature was designed. Furthermore, automatic DST (daylight saving time) was realized. Components The hardest part of this project was to cut the aluminium case with a dremel. Arduino nano Adafruit 4-digit 7-segment display Realtime clock DS3231 Backup…
Simple Arduino clock without buttons and automatic DST (daylight saving time)
Overview: This is a project to build a clock with an Arduino, a 4-digit 7-segment display and a real time clock. I want to show how a 7-segment display and a real time clock DS3231 can be used to build a simple clock, that runs, runs and runs with automatic daylight saving time adjustments. Components:…
