Description Th1, the 50K thermistor, is a standard type. Mine was a bar or rectangular looking thingy. Available from Tandy/Radio-Shack. Almost any type will do. I experimented with different models from 22K to 100K and all worked fine after replacing the trimmer pot. The one used in the above circuit diagram was a 50K model. ThisRead More

Raspberry Pi Stack – A platform for learning about IoT
47 Projects to Do With a 555!: These are a whole bunch of things to make with the 555 timer IC with a note for each picture. I do not take credit for these schematics, they were made by Collin Mitchel. As you would probably think it took me a very long time to make this but it w…
Use an Arduino, an Android smartphone, and our free app to connect your devices and automate your home.
Today we’ll expand Arduino’s digital resources thanks to an I2C bus equipped shield and we’ll allow the management of the board via a bluetooth connection RN-42 through an Android systems. All Arduino boards feature a number of digital I/Os. For the simplest projects, such resources are usually more than sufficient, but in those where they […]
Reversing Valve is a Part of HVAC which Convert Air in Cooling and heating. In this Post you can see Reversing Valve Diagram in Heating Mode and Cooling Mode. In this Diagram you can see that how to work Reversing Valve and how to convert air in heating and cooling mode. This Diagram is very easy to understand.
With the new RN-42 Bluetooth module we created a Bluetooth remote control board and transform it into an Android Based system: a board that manages input/output and it’s equipped with four outputs relays and four optically isolated inputs, that can be controlled via Bluetooth. At the software layer, the unit sports three operation modes: manual, […]
El versátil integrado 555 se presta no solo como temporizador o intermitente sino también como flip flop RS o Toggle, muy útiles para construir interruptores con autorretención que se usan en campo industrial. Veamos como usarlo con ejemplos prácticos.
Control a Solenoid With Arduino: This Arduino Solenoid Tutorial shows how to control a solenoid using pushbuttons and a relay with your Arduino compatible controller. Solenoids are electromagnetically driven actuators. When voltage is applied to the solenoid coil the electromagneti…
