Arduino driven bathtub

If you want to relax on bath, you need right water level and temperature. If you add bubble, then it’s supper. raptor_demon is working on Arduino based bathtub controller. He wants to set up system where bath could be prepared with single button click and with Ethernet support even remotely. First o all, instead of using standard Arduino he built his own custom board where all controller parts fit in. He added three mechanical relays that control fill valve(or pump), Soap dispenser and drain valve. Temperature of water is taken with DS18B20 sensor. He also added 343MHz receiver for remote in tub temperature. There are plugs available for flow meter and Ethernet – those aren’t implemented yet. He placed controller in to laser cut plywood enclosure with Adafruit LCD screen shield in front. Continue reading

The Genuine Arduino Control Panel for Motorcycles

There are many electronic projects have been built based on the Arduino. You might have seen the Arduino Control Panel for Racecars or SUV, but have you ever heard about an Arduino Control Panel for Motorcycles? Yeah, it sounds like pretty amazing, isn’t it? Well, today’s your lucky day, where we’re going to build an Arduino Control Panel for motorcycles. Before that, you should know that the main purpose of developing this arduino control panel is to measure various locomotion parameters, such as the speedometer, tachometer and gear indicator. Although it’s still in the prototype stage, but it works perfectly without any hassle. For this project, you have to prepare these following components: A standard Arduino, A small LCD, and Bluetooth . Basically, the device is connected to the electrical system of the motorcycle to receive pulses from the tachometer and using a reed switch for wheel rotation. It starts to calculate the wheel speed in Revolutions per minute (RPM), divides it into most recent engine RPM and obtains a unique ratio for each gear! It’s very a fun and… Continue reading
