ACES LED Tester for 2023/2024

A device that can quickly confirm whether an LED is still functional is a useful asset to have on your bench. Retail LED testers are readily available but ACES prefer to make their own tools. In doing so, custom features and modifications can be added. In the device described below, not only can single LEDs be tested but, later in the course, you'll have need to test your common cathode (CC) 7-segment display units. The female header pins allows for easy insertion and testing of this display unit.

Familairize yourself with the components outlined below and listen carefully to the soldering instructions provided in class to successfully assemble and confirm your ACES LED Tester.

Again, follow the instructions carefully and with caution as there are no replacement parts
