| | | | | Still working on my bench power supply, and wanted to move from my 16×2 retro LCD to something a bit more funky, and found these which use the Samsung S6D02A1 chip. 1.8 Inch Serial SPI TFT LCD Display Module With Power IC SD Socket At the time of writing, you can get these from a UK warehouse for £3.30 shipped for a single unit. That's awesome. However, the comments were quite bad and many people had issues with them - no matter how it was wired an Arduino wouldn't drive it. After lots of trial and error... | |

| | | | | I wanted to build an application that could sniff i2C transactions. In particular, I was interested in the actual data transactions between the Wii NunChuk and WiiRemote. This particular data interchange utilizes 400KHz i2C protocol. So, I thought this was a good opportunity to use arduino interrupts, especially the change on pin interrupts. What I... | |

| | | | | Hi lovely people! ?? In the last article we talked about the soil moisture sensor. In this article, we will take a look at how to measure temperature using DS18b20 and measure light intensity using a photocell. Step 1: Wiring up the Circuit We will be using: Arduino UNO Breadboard DS18B20 Temperature Sensor Photocell (any typical one) 4.7K? resistor 10K? resistor Jumper Wires Wire up the circuit like this: | |

| | | iperf3 is useful for testing the network throughput of your local network. It can help to indicate network bandwidth of individual nodes on your LAN. Do you have one computer that seems perpetually slow? Then iperf3 may be able to confirm this potential issue. A WAN speedtest service like Google's will not necessarily indicate the speed of individual nodes on your LAN. Rather, it is better suited to testing the throughput from your home to the public Internet. | ||
