HackerBoxes #18 – Using an Arduino to Program a New MCU for the Transistor Tester

As described in my original post on the HB #18 transistor tester, if you want to try one of the various builds found online for the transistor tester, a new ATmega328P MCU can be programmed using a USBTiny.  I also wanted to try programming a new MCU using one of the Arduino clones that came with a previous HackerBox. The Arduino clone I used is the RobotDyn Arduino UNO R3 Microcontroller Board included  with HackerBox #16.  If you use this board, you will need to make sure that you have the drivers setup, and I would load a Blink sketch to test and make sure it is working before proceeding.  Step 12 of the HackerBoxes Starter Workshop details how to do […]

How to Change the MCU Code on the HackerBoxes #18 Transistor Tester with a USBTiny

Updated 05/13/17:  It is possible to use an Arduino to upload new firmware to the HB transistor tester.  I added a tutorial on using the Arduino clone from HB #16 to upload firmware to an ATmega328P. Also, the GitHub project for the transistor tester seems to have two main authors – Markus and Kübbeler. This tutorial for the USBTiny uses the firmware build by Kübbeler while the tutorial using the Arduino uses the build by Markus. This is a short tutorial on how to change or update the code used on the MCU for the Transistor Tester included with HackerBoxes #18.  This involves a few steps to get it working, none of which are particularly difficult, but it is a bit of a pain […]
