It does not take more than a casual glance at the pictures above to recognize that while functional, these are not ideal solutions. This tutorial was kept simple as an introduction to some basic electronic components and so that you can learn how a breadboard works before tackling more complex circuits.Bench power supply connected with alligator clips and jumpers I hope that you enjoyed this tutorial and found it useful. The wire link connects the bottom resistor lead to the bottom horizontal connecting strip which is then connected to the black lead of the battery. The resistor is not shorted out because it jumps across the middle insulated channel of the breadboard to a vertical connecting strip below. The LED connects to the resistor using a top vertical strip. The red lead from the battery is joined to the LED via the top horizontal strip of the breadboard. This photo shows the circuit built in this tutorial with the connecting strips of the breadboard that are used by the circuit in blue. Click the button below to make a donation.

If you try to connect them the wrong way, they won't clip together, but they will put reverse polarity on the circuit for a moment which may destroy the circuit, so be sure to connect the battery the right way around the first time. the battery and battery clip each have a pair of terminals and they will only connect to each other one way. The opposite type of connector on the battery clip must be connected to the battery terminals, i.e. Make sure to connect the battery clip to the battery the right way around. Step 5: Plug the Battery into the Battery Clipįinally plug the battery into the battery clip to power up the circuit and switch the LED on. Plug the black (negative) wire of the battery clip into the bottom rail of the breadboard. Plug the red (positive) wire of the battery clip into the top rail of the breadboard.
Step 4: Insert the Battery Clip into the Breadboard Insert a wire connector into a hole directly below the resistor lead and into the bottom rail of the breadboard. Step 3: Insert the Wire Link into the Breadboard It does not matter which way around the resistor is plugged into the breadboard. This connects the LED cathode to one of the resistor leads. Plug one of the resistor leads into a hole directly below the cathode lead of the LED and the other lead into a hole below the middle channel of the breadboard. Don't try to remove the tape as this will leave a sticky mess on the end of the resistor lead which will then end up in your breadboard.īend the leads of the resistor as shown below. Cut the resistor lead as near to the tape as possible. Use the side cutters to remove a 1k resistor from the string of resistors if they are taped together. Step 2: Insert the Resistor into the Breadboard Plug the longer lead (anode) of the LED into the top rail of the breadboard and the other lead into a hole in the main part of the breadboard as shown: Start by bending the longer lead of the LED as shown in the previous photo. Step 1: Insert the LED into the Breadboard This video clip will show you what you will be doing – step by step instructions follow:
This diagram shows the alternate circuit: Building the Circuit It will be represented by text that will show what voltage must be connected across the circuit. Often the battery or power source is not shown in the circuit diagram. Connect the cathode of the LED to the negative terminal of the battery (black battery clip lead). Connect the other lead of the resistor to the anode of the LED. This circuit diagram tells us (clockwise from the battery): Connect the positive terminal of the battery (red battery clip lead) to the 1 kilo-ohm resistor.
