Serial Voltage Level Converter - Arduino

Have you ever needed a serial FTDI adapter for a 3.3v microcontroller but you only have a 5v adapter? Build yourself a voltage level converter and solve the problem http://homediyelectronics.com/projects/arduino/seriallevelconverter/

Build an LED bargraph circuit with transistors. Not an integrated circuit in sight http://homediyelectronics.com/projects/led_bar_graph_with_transistors/

You don't need to search for an integrated circuit to make a bargraph display. Just a few cheap LEDs transistors and diodes will do nicely.

Watch me as I blow up a resistor to explain why resistors have a maximum power rating.

Let me show you how servo motors work and what you need to do to drive them. There's a handy library that you can use with Android which makes things very easy called 'Servo'. But what if you need to drive the servo some other way? If that's the case then you will need to know something about how they work.

I will show you how to connect one up and write a very simple Arduino sketch to experiment with. I explain exactly what goes on inside a servomotor and I finish up with a set of oscilloscope traces. If you want to know more about servo motors then read on.

What are servo motor, how do they work and what can I do with them?

Build yourself a cheap but impressive pc based sound card oscilloscope that you will use time and time again when building electronic circuits.

This is my new book inspired by interest in computer oscilloscopes.

Following on from the Arduino Distance Sensor project here is an updated version of the software sketch. Two new display modes have been added and the 'Select' key on the LCD keypad is used to swich between display modes. Full explanation of the software is provided.

New issue #2 of the Home DIY Electronics magazine out now.
Following on from the previous issue we add two additional display modes and switch between them using the LCD shield keypad.

Also in this issue: An update to the single transistor touch switch project. By adding a transistor to form a Darlington Pair configuration the circuit can be made 100 times more sensitive.

Introduction
Electronics and programming have been in my blood since I was at school and that was a long time ago. I've done enough and seen enough to know that you can achieve anything if you put your mind to it and adopt the right attitude. I now encourage others to do just that.
