The ESP8266-01 only has a limited number of I/O pins (only 4). Fortunately these pins can be used for I2C communication, allowing us to add a hoist of other chips. I wanted to add an RTC to the ESP8266-01 and for testing purposes I did not want to always have to go to an ESP8266 …

First, you need to know that a lightstrip is a bunch of LEDs daisychained together. The three contacts are +5v, GND and DI (data in, AKA DIN). If you are using the same lightstrip, you can solder just 3 wires… Now on to building …
How to make a shark puppet with blinking LED lights for its eyes! The two LED lights are going to turn on when the shark’s mouth is closed the first time, after the first time the lights come on, the LEDs are going to blink when the mouth is closed. Step 1: Preparation Things you …
This instructable will guide you to glow an LED using a touch sensor which means that the LED will glow when you touch on the probe of the sensor. The project uses the Mediatek linkit one connected to a touch sensor and an LED. As soon a touch is detected, the output goes high which …
Create your own rc controlled led-strip for individual room illumination! Most rgb-led-strips are controlled by an infrared remote control. To turn it off or on or change the color, you have to stay in front of the receiver. This is boring and not really smart. To control the light in a cooler way, i developed …
Who does not want to have stunning lamp which can display animations and sync with other lamps in the house? Right, nobody. That’s why I made a custom RGB lamp. The lamp consists of 256 individually addressable LED’s and all of the LED’s can be controlled via a smartphone app. Additionally, you …
For my Fab Academy class I have to create a board with a microcontroller, a button and a LED. I will use Eagle to create it. Step 1: ATtiny 1614 I will use the ATtiny 1614, so I will use the reference of the echo Hello Board ATtiny 1614 from Neil Gershenfeld. I will also …
I love LED chasers. A bunch of LEDs neatly turning on and off on a precise timing – lights running one way, then the other way… It’s relaxing, soothing, and hypnotic. There are so many LED chaser/scanner/sequencer circuits out there, some are made with discreet transistors, some based on logic ICs, and more and more …

I have seen RGB mood lights using Arduino, PIC, and larger AVR chips, but never one with the ATtiny85. That’s why I decided to make one. This mood light is super simple to make and all the parts can be purchased online for about $5.00 total (not including the Arduino used to program the chip). …
This example code and simple wiring demonstrated how to setup an AVR ATtiny85 processor to react to external interrupts. Whenever the voltage changes on the chosen input pin (pin 6 / PB1), it executes the interrupt service routine (ISR), checks the current voltage, and sets the output pin (pin 3 / PB4) to match. This …
