This guide will tell you step by step how to flash a Hobbywing 20A esc with BLHeli firmware for multirotors. It will be the same procedure for any other ESC with a silabs chip, you just need to find the pin-outs for…
In this tutorial I’ll try to show you how to easily tell an arduino what to do from a C# program using serial communication. The only thing the C# program does is send a byte to the arduino, and the…
I always wanted to make something out of the microphone sensor I got, it’s just been laying in a compartment-box until recently when I got the idea of a music beat blinker. Basically it just reads the analog value from…
Why not? First off we need to download the server software, you can find it here. Look further down on the page and you’ll see a link to a Minecraft_server.exe, thats the one you need. Download it and put it in…
How about a easy and simple tutorial on how to make a sort of security sensor using laser and a light dependent resistor? It’s just as simple as this, the LDR reacts when it gets less light than the laser-dot in the…
Hi I just want to write a few words for those new to Arduinos, or those looking for tutorials, guides etc. If you haven’t got a Arduino board yet, you can get one from several places, I’ll list some of…
My new project, is a simple led-strip which shows CPU load. 9 led’s are used for this, could have used more but my tiny breadboard couldn’t hold more. Anyhow, it uses serial communication to receive how much the totalcpu usage…
Made a followup to my light tracker, except this one can go up and down. So it follows light in more directions than the other ones. [youtube=http://www.youtube.com/watch?v=0Fw6ausjl9o&w=425&h=344] Made of some cheap plastic-foam, wont last forever but long enough for me…
[youtube=http://www.youtube.com/watch?v=iEhX27ahreI&w=480&h=385] This is how to make a simple light tracker/follower with the Arduino. The components you need apart from the Arduino is: 2x Photoresistors: “PHOTOCELL2 Miniature Photocell”. 2x 470 Ohms resistors. 1x Servo. And of course some wires, and a…
It’s always good to have servos that works like a geared motor. That also can go in both direction and speed is adjustable, it’s very handy in robotic project or general vehicles. The servo I’m using is a Mystery Micro…
