Arduino RGB LED strip control with MOSFETs and optocouplers – Part 1 – The Hardware

Today we tinker us a driver for RGB LED strips using an Arduino. In addition, we use optocouplers to separtae our Arduino from the control unit with the 3 MOSFETs, which is not absolutely essential, but brings some advantages to the circuit.

Tiny RTC DS1307 Real-Time-Clock with an additional temperature sensor DS18B20

In the following article we extend the Tiny RTC module with a DS18B20 temperature sensor, which either already exists on the board or we simply add by soldering. This article is an extension of: Time and calendar functions with a real time clock module based on the DS1307 and an Arduino.

Simple FM stereo radio with a TEA5767 breakout module and an Arduino

To be a little entertained when tinkering, we build us today a small FM stereo radio using a slightly older, but extremely inexpensive, TEA5767 breakout board. However, by this time it will be a little more complicated because we need to solder and have to build some adapters.

Time and calendar functions with a real time clock module based on the DS1307 and an Arduino

Since Arduinos have not directly the possibility to save time, we expand our Arduino with a small DS1307 Real-Time-Clock (RTC) boardWhich can, battery powered, “remember and count” the time and the date.
