D-Led Shield v1.0 (for monitoring)
The thing here is, sometimes we have a hard time checking out which I/O pins are LOW or HIGH, especially when we are dealing with LED, motors, etc. Now, here is one of the solutions that you can make in order to have yourself a smooth sailing progress in programming your prototype or project.
One of the shields we sell at our shop in e-Gizmo Mechatronix Central, is an LED shield. It is one of the shields that can help you monitor your I/O pins. Another thing is, in some countries, this kind of shield is not sold and most probably, only prototyping shields are available.
I shall now provide you a DIY LED shield that will you a LOT in your projects.
19 LED in series with your arduino’s I/O pins for monitoring.
Step 1: Materials
Step 2: Schematic
Here is how I soldered the shield and I know, I’m actually not proud of how I solder stuff since my soldering gun is not really that great.
The running “rail-like” solders are all connected to the ground.
Step 3: Procedures
STEP 1: Buy the materials! I am very particular with this since in some countries, hunting the materials are really tough. So I’m going to give you tips wherever you are in this universe.
In North America, check out Radioshack or try buying from Sparkfun through shipping.
In the Philippines, you can visit Raon and look for DEECO. They sell LEDs for a very low price wherein you can buy 20pcs for I think P25.00 only.
If you have the chance, visit our shop (e-Gizmo) in Taft. The prices of the materials are listed above and I made our shop as a reference for the materials’ prices.
