Flex Sensor Interfacing

Flex Sensor Interfacing with AVR Microcontroller Using Atmega

In this tutorial we are going to interface FLEX sensor with ATMEGA8 microcontroller. In ATMEGA8, we are going use 10bit ADC (Analog to Digital Conversion) feature to do this job. Now the ADC in ATMEGA cannot take a input more than +5V. What is a Flex Sensor? A FLEX sensor is a transducer which changes its resistance when its shape …

New Wireless IOT Sensor Layer

New Wireless IOT Sensor Layer for Home Environmental Monitoring System Using Arduino

This Instructable describes a lower-cost, battery-powered wireless IOT sensor layer for my earlier Instructable: LoRa IOT Home Environmental Monitoring System. If you haven’t already viewed this earlier Instructable, I recommend reading the introduction for an overview of the capabilities of the system which are now extended to this new sensor layer. The original LoRa IOT Home …

DC Motor Speed Control schematics

DC Motor Speed Control using GY 521 Gyro/Accelerometer and Arduino

In this article, we are going to control two motors by using the GY-521 accelerometer module. The speed of the motor will increase or decrease upon moving the GY-521 module up or down. On moving the Gy-521 towards the downside, the speed of the first motor will decrease and the speed of the other motor will increase; while …

Antique Phone Doorbell

DIY Antique Phone Doorbell using Arduino

Bryan Zimmer emailed us this fantastic retro-themed DIY hack, a most timely submission as we just revisited the noir art deco-science fiction classic Dark City and we think this would have perfectly fit in the world (or in Adama’s quarters on BSG). Bryan gives step-by-step instructions of how he converted a 1940’s Swedish-made Ericsson bakelite original into a …
