Little update:

I’m currently moving, but I have a server set up to host all the files for the Arduino code. Sorry I didn’t get this sooner, but  this will be uploaded after the move. I was also in a car accident recently, so I have a bit of a break from other projects and will be updating this blog quite often. Nothing like some free time…

Quick Update

It would appear that if you copy the code I posted, any occurrence of a quotation mark is obfuscated somewhere between copying and pasting into the Arduino IDE (Thank you Denis for noticing!) Replacing all quotation marks fixes the issue. I’ll look into changing the font of the theme or the whole theme completely at a later time. Sorry for the inconvenience.

Soil Moisture Sensor

I recently bought another cheap chinese piece of electronics. When I say recently, I mean I purchased it in October and received it on the 23rd of December. Complaints aside, it’s a “soil moisture sensor” which is supposed to allow you to check your plants water levels.

How to use a cheap “Voltage Sensor” With Arduino

I recently purchase a cheap “Voltage Sensor” from eBay. It arrived today, and after a little tinkering, I got it ‘working’. It’s a simple creature, only having a couple resistors, screw terminals, and header pins. How this part works: It’s just a resistor voltage divider where R1=30 kΩ and R2=7.5 kΩ. Continue reading

Sorry for the lack of updates

I’ve been commissioned for a job. A ‘carputer’ for a 1954 Ford F100. I will be posting the details of that project once I actually get to the hardware side of things. I’m currently only coding the UI (Which sadly will remain closed source) But the sensor setups, and Arduino portion should be available. I can say it will be a combination of an Arduino, Raspberry Pi, RFID, and Wireless (which appears to be 2.4GHz at the time of writing.) More info to come!

Remote Control Tank: The Transmitter

This is a very basic controller, one that doesn’t allow fine tuning of speed or how sharp it will steer. It would be easy to modify the code I used to accept an input that could allow of better control. For now this is what I have, and what I will be working with. If you have questions, feel free to ask in the comments.

BOM(incomplete, because the project is incomplete):

This is very similar to a previous project, except this one has 4 buttons and accounts for relay on/off timings. I recycled the code from SparkFun’s 315MHz transmitters page, modifying it to suit my needs.
