HOW TO – Make a pogo pin testing jig. For more complicated projects, you may need to have a longer testing procedure in which case we can make multi-step testers that also keep the PCB held down with little ears! The plastic pieces hold down the PCB against the pogo bed.
This tester, when used with a little batch script, performs the following test:
Reprograms the board’s fuses and flash with a bootloader (via the ISP port). For this part we’re using the Arduino as an ISP programmer (there’s a sketch that does this)
The computer then bootloads (via USB) a pin-by-pin testing program
Once the board indicates the test completed, the computer erases the testing program
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
