Sometimes, people wonder about the practical side of using an arduino. I do get asked what is the real use for some of the articles I post here. Are these ‘gadgets‘ just toys or do they have a practical use? Most people who ask though, are not that familiar with arduinos or microcontrollers in general. …

Previously, I wrote about RS485 communications between two Arduinos using a MAX485 IC. The link for that post is HERE. It showed one Arduino as a tranmitter and the other as a receiver. This post is very similar, however, I am using a different IC, the SN75176BP. This post is about SN75176 RS485 communications between …

There are various ways for two Arduinos to communicate information. A common way is serially via RS232. However, RS232 has distance limitations. If there is a need to serially communication over a longer distance consider using RS485 instead. A couple of MAX485 ICs can facilitate RS485 Arduino communications over that longer distance. Two MAX485 ICs …
