DIY USB to TTL Converter

Now that the PC’s com port or Serial port is almost obsolete there is quite a lot of requirement for USB to TTL or USB to RS232 converter. USB to TTL converters are required for interfacing microcontrollers to PC it is also required for loading code in Arduino Mini, setting/modifying ESP8266 firmware. Over here we are going to make a do it yourself (DIY) USB to TTL Module on a breadboard. Lots of USB to TTL ...

Electromagnetic Field Detector using an Arduino

Ever electronic device emits a certain amount of electromagnetic fields and we can use this radiation to learn a few things about the circuit. In today's instructable I'm going to show you how to build your own electromagnetic field meter using an Arduino. This device can be used to detect mains voltage, static electricity and radiations from certain devices. It can also be used to detect ghosts :P. So lets ...

A Smart Night Lamp for Kids

You can download our e-book ‘Learn Arduino from Scratch’ from this link Few weeks ago I heard my nephew (aged 7) complaining of the dark at night. Basically he was afraid ? So I decided to put knowledge into practice and build a night lamp for kids. Since the project was intended for kids, I thought of making the lamp change color every now and then. It should also be sensitive to light so that if the room ...

Arduino Color Mixing Lamp using RGB LED and LDR

What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is change in light in the room. So this lamp will automatically will changes its color according to the light conditions in the room. Every color is the combination of Red, Green and Blue color. So we can generate a ...

Auto Intensity Control of Power LED using Arduino

Be a bright spark, lights off till it’s dark!” sometimes we forget to turn off the lights and waste electricity and you must have also seen street light turned on in the day. We have already built few circuits on Dark detector where lights turn off automatically if it is bright outside and turns ON if it is dark outside. But this time, in this circuit we are not only turning On and off lights based on light ...

Using BMP180 for temperature, pressure and altitude measurements

The BMP180 is a new generation digital barometric pressure and temperature sensor from Bosch Sensortec. In this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board for measuring the surrounding temperature and pressure. We will also discuss about retrieving the sensor altitude from its pressure readings. Experiment setup Bosch Sensortag’s BMP180 ...
