“This project is microphone based and require minimal external components. 2 x LR44 coin cells are used so that I can have the whole structure working in the confines of a 170 tie-point mini breadboard. ADC10, TimerA interrupt LPM wake-up …
“pedalSHIELD MEGA is a programmable guitar pedal that works with the Arduino MEGA 2560 and MEGA ADK boards. It includes a 1.3 inches OLED screen, a True Bypass footswitch, 2 programmable push-buttons and an analog input/output stage. The …
“Pi1541 is a real-time, cycle exact, Commodore 1541 disk drive emulator that can run on a Raspberry Pi 3B (or 3B+). The software is free and I have endeavored to make the hardware as simple and inexpensive as possible. Pi1541 …
“The easiest way to build a remote controlled Strandbeest Model! You’ve seen the kits available for around $10 or less for a Strandbeest wind walker, but what if there is no wind? In this tutorial, I go over how …
“If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In …
“Previously I talked about a LED box. I explained how to operate a ws2812 led strip. Thoses strips can be connected together in serial. After a first try one year ago, I built this clock from scratch with 360 leds …
“In this instructable we will learn how to bootload the ATMEGA2560 chip and how to upload Arduino Mega sketches to it.”
“The idea with this project was to create a lamp that also functioned as a visual representation of a blackhole in a 2D universe. As predicted by Einstein’s theory of general relativity, objects of mass distort the fabric of …
“Most of us think of robotics as a rather difficult hobby. Well, it is not so. When we are getting started with Arduino we should never go for making the very tempting but difficult-to-make projects. Arduino is a rather easy …
“What’s this then?A breathing, coughing, air-quality-sensing, Google-Sheets-logging, real-live-plant-having planter! Using an air-quality sensor and a hidden Raspberry Pi Zero W, this little planter personifies a plant to sense indoor air quality. Code and miscellaneous resources (laser cutter PDF …
