A breadboard sometimes known as a plugboard is a reusable board used to connect electronic components together without needing to solder or tie wires together. It makes it easy to quickly build circuits which you can keep built or disassemble to reuse components. Be careful not to connect the pins of one component to the same rail as you might short something! There are two types of rails; power rails run vertically along the edges of the board. Regular rails run horizontally. Power rails are marked with positive and negative signs like the terminals on a regular battery.
Tutorial: Adding Sensors ( & Modules ) to Your Arduino Data Logger
I am using only parts from the Arduino starter kit I got from Deal Extreme. Also there are many different versions of the LCD display with different pinouts and I couldn’t really find which the DX version exactly was. This way you can solder wires to it, solder a connector on it, whatever you want.
//Setup the search to find the device type ‘DS18B20’ (0x28) if it is present.
The output voltage of the sensor is directly proportional to the temperature in centigrade. LM35 is a 3 pin IC and the figure depicting the pins is shown below. A similar precision temperature sensor is LM34 that can be used to measure temperature in Fahrenheit. It can be used to get the temperature directly in Fahrenheit. We used a 16X2 LCD in this project. Pins 1 and 2 of LCD are connected to ground and supply respectively. The other terminals of POT are connected to supply and ground.
They are connected to supply and ground respectively. Pins 11 — 14 D4 — D7 are connected to Pins 5 — 2 of Arduino. Pin 5 RW is connected to ground. Pin 6 E is connected to pin 6 of Arduino.

The Hydreon sensor is not as accurate as a tipping bucket rain gauge. It tends to read high in comparison. However this sensor will detect rain before a tipping bucket gauge. This sensor requires 12V DC to operate.

Read the fortieth bit While the “delay before start” is not 5 seconds, and the “time per bit” is not 1 second, what actually happens is otherwise as the above The sending of the data is almost exactly as above. The receiving is fancied up a bit. Create 5 element array DataByte Basically, as we go through the “FOR” loop, if we get 0,0,0,0,0,1,0,1, we should, at the end, have “5” in the relevant element of the DataByte array. Binary is “5” in our usual system for writing down numbers.
The “tricks” for assembling a number from a stream of bits can give you a headache, but they are simple When you know how. But they’d be a distraction here. We are assuming, with reason, that the time to “read a bit” and to “change contents” will be but a tiny fraction of the time a bit is displayed. That’s pretty well “it”.
Arduino Based Digital Thermometer
My Touch Interface Aquarium Controller Arduino Grab a beer and a bag of potato chips, because this is one incredibly long post. Sorry, but I didn’t know how else to do it. If you don’t like reading, just scroll down to pictures. This project started out with a relatively small scope, inspired by stilo , which is a touch screen aquarium controller that I stumbled across. I wanted to control power everything including CO2 , dosing pumps, and my Current Satellite Plus lights through a touch screen interface.

I happened to have one too, before seeing this post, I was in the progress of building a replacement controller based on ESTechnical. I got to the stage to have the PCBs made because I already have all the parts except the thermocouple amplifiers. I added isolation cutouts on my own PCB to improve the safety, where high mains voltage are separated from the low-voltage input circuit, as you can see from the image below.
I am a bit sceptical with the accuracy of the design. Werner has thoughtfully mapped out all the processor pins usage and place it in the t However, there is one problem. Since I already got the MAX Another bus on the processor that is of interested is the I2C bus. I did not take the power from the original controller. Instead, I tapped the raw DC from the bridge rectifier on the original controller and fed it to the 5V and 3.
This should minimize any noise from the original controller, my clone board also had separate analog ground plane for the MAX According to the datasheet , the chip communicates with the processor through function IDs and data buffers. The chip can hold bytes of data. Once the I2C communication completes, the chip will pass on the data onto the SPI bus to the selected device automatically.
The 2 players automatically win and lose so their scores show the hours and minutes. All the parts are easily available on eBay and the software code is free! The clock has lots of different display modes to choose from:

Albert winkleink Hickey , a friend of mine, who also runs the Egham Jam put me onto these when he did his buttonflash game. Albert has a useful hobby of trawling ebay for bargain-basement electronics. A few weeks ago he showed me the Wemos D1 mini. Wemos D1 mini On inspection, it ticked all my boxes for this project. They arrived recently and I took a little time to have a play.
Installation Installation was fairly straightforward. This is what we like. Looking through the examples is quite an eye-opening experience. There are quite a lot of them each of the items in the screenshot is a menu , but it gives you a flavour of what these boards can do. Wemos Arduino Examples You can have them working as web client, web server, or access point to name but three modes. Port Numbering Can Be Tricky!
The only caveat is that the port numbering is a bit confusing.
Now install the necessary softwares to manipulate the I2C bus. Assuming your Raspberry Pi is connected to Internet, issue the following commands at a shell prompt. As the next step is going to be little messy but be rest assured that soon you will have enough knowledge to expand your Raspi with as high as 8 — 16 — 64 or whatever you like no of GPIOs and then controlling these extended GPIOs by only two wires from your Raspi! Once the softwares are installed reboot your Raspi so that these effects take place permanently.
Together they comes for around Rs: Connect them as shown in the figure-2 Testing:
I also tried to hook up the Dallas sensors (DS18b20). I have tried about 4 different pcs. and none of them will work. I have checked the cable and its good, i have checked the power and the sensor is getting v from the EmonPi.
Interfacing the PID shield with a K-type thermocouple. A PID controller is like a kind of fancy thermostat , but can be used to control pretty much any kind of process, not just heating and cooling. The goal of this project was to make a PID controller from scratch with minimal skill and know-how. The shield had to be easy to build using minimal tools, with components that were easy to order. Fortunately, it proved possible to recreate most of the functionality of the osPID on hand-soldered prototype board using through-hole components.
With the exception of the Arduino all the components can be ordered directly from Tayda. Although intended as a DIY project this device is very capable. With the addition of an SSR module and suitable cookware, the stripboard PID shield could be used directly in applications such as sous vide food preparation, brewing, and making the best espresso this side of Milan. There wasn’t space for an output relay, the op-amp buffer and low pass filter for the thermistor were omitted, and the thermocouple interface chip was not available as a through hole component.
On plus side, it was easy to add the ability to use 1-wire temperature sensors like my favorite DS18B It would have been nice to spaced things out a little more, but I chose to constrain the board to a standard size so that the the shield would not dwarf the Arduino underneath. This project implements different temperature sensors:
Make an Arduino Temperature Sensor (Thermistor Tutorial)
Zoos around the country to help support it because people have a responsibility. Feel free to contact me on hookup gps 19 and see the show because i find it. Hi, I used this lesson to create arduino gps data logger. I used exactly the same hardware except I used arduino mega I get the serial monitor output as follow.
Some hook up via usb then connect to gpoi and that solves some issues.
This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface.
Everything appears to be working as it should, the Vdc hooked to the same terminal as the ground from the storm x causes me some concern. I would rather have my fans do a ramp, rather than jump from the minimum to the maximum, so I would like to rum my fan off one of my available channels. Is this a viable option?

Reading the Analog Temperature Data Unlike the FSR or photocell sensors we have looked at, the TMP36 and friends doesn’t act like a resistor. Because of that, there is really only one way to read the temperature value from the sensor, and that is plugging the output pin directly into an Analog (ADC) input.
While searching for a simple way to measure temperature using my Raspberry Pi I came across the DS18B20 1-wire digital temperature sensor. This promised an accurate way of measuring temperature with a few wires and almost no external components. The device only cost a few pounds and it seemed too good to be true … So I bought one. Within a few minutes I was measuring the temperature with it. It is so simple to use and the perfect starting point for creating a Raspberry Pi based temperature data logger.
It has three pins and comes in a TO package which means it looks similar to other devices you may have used such as transistors. Pin 1 is Ground.
