An interesting project and already much discussed in the forums and also in videos.Although it appears complex,it is a simple idea and fun very purpose. Mounting material: – 27 LEDs matte– Microprocessor ATmega8– Electrolytic capacitor 47UF 16V– Veroboard– Small wood board at the minimum 10x10cm– 50 cm wire tinned (excuse me, I’m portuguese and my […]

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

A while back, I posted up a quick and dirty “el cheapo” method of getting started programming the Atmel AVR series chips: Ghetto Programmer (version 1.0) Since then, I’ve vamped, re-vamped, and otherwise improved my setup. Thought it’d be nice to document it. The goal was to get a flexible, compact, portable, use-anywhere, AVR-based microcontroller prototyping

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).

Pulse Width Modulation (PWM) is a powerful technique where width of the pulse is changed by keeping the frequency constant. The technique is used in many control systems today. The application of PWM is not limited and it is used in wide range of applications such as motor speed control, measurement, power control and communication etc.

Hall sensors works on the principle of Hall Effect proposed by Edwin Hall in 1869. The statement proposed says, “The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.” So, what could

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

2 weeks ago my daughter had a genius idea to make a quick reaction game with rainbow colors (she’s a rainbow expert 😀 ). I instantly loved the idea and we started thinkering how we could make it into a real game. The idea was. You have a rainbow in randomly shuffled colors and the
