You will notice that my connections to the board are very neat and easy to follow. In Image #6 and Image #7 you can see the completed power supply. The capacitor has a marking to show which side connects to ground. One capacitor goes between the input to the voltage regulator and the ground, the other goes between the ground and the regulated 5 volts. Likewise, the capacitor holds extra power for when there is a surge from things starting and stopping. The tank holds enough water to even out the flow. when you flush you need a large flow of water all at once. One way to think of them is like the water tank in your toilet. They act to smooth out the voltage when things like LEDs turn on and off. In Image #5 you can see that we have added a capacitor.

We insert the pins into the breadboard and install the diode. This is done to provide a stronger connection that won't turn or jiggle loose. If you look at image #3, you can see that the wires are soldered to TWO pins. (Single Inline Pins) The wires are soldered to the pins and then can be inserted into the breadboard. they do not plug into a breadboard very well so we need to make it so that we can install the connections properly. The 9 volt battery clip uses stranded wires. it connects to the input of the voltage regulator. The diode has a line printed on it, this should be on the most negative side, in our case. The reason we install it is so that if we connect the battery backwards it will not let the current flow and will protect our circuit from damage. it will allow current to flow in only one direction. We also want to install a diode into the circuit. The 9 volt battery works well in this application. The chip needs to have greater than 6 volts to be able to regulate it down to 5 volts. It has three pins, the first is the input, next is the ground, and last is the output voltage. We will use a voltage regulator called a 7805. So where do we get 5 volts? We will build a power supply from a 9v battery. we will be connecting the power and ground. Tiny 261, 461, 861 Datasheet (PDF) Tiny 26 Datasheet (PDF)īelow is an image with the pins for the chip we will be using. The new chips have more functions that can be assigned to each pin. If used, simply change the header by selecting the appropriate chip and recompile the program to use the newer version.
Note: The Tiny-261, Tiny-461, and Tiny-861 are pin compatible newer versions of the Tiny-26. Once you understand what we are doing here, you may want to try a more powerful chip like the Mega-328P which has more pins and more memory.
It is a smaller microprocessor, very inexpensive, and easy to understand. I picked an older Atmel chip, the Tiny-26 to get started.

your first project can be to change the code slightly to make it into a traffic light. In this Instructable we will blink some LEDs in sequence.
What we will do here is to start with a bare breadboard and build each connection and each component until we have everything we need to program a microcontroller to do something. I have not seen an Instructable that takes you from nothing and builds on each step.

I have seen plenty of Instructables showing how to work with microprocessors, but they all assume that you have worked with them before and know what you are doing.
