HFE test using Arduino transistor tester. 7、FAQ for Engineers Q1: Can BC547 handle 12V relays? Yes, if relay coil current ≤100mA. For larger coils (e.g., 250mA), use a MOSFET. Q2: Why my amplifier circuit oscillates? Add 100pF capacitor between Collector and Base (Miller compensation...
In this post we assemble and review the Original Hiland DIY M12864 Transistor Tester Kit. The kit is capable of identifying and measuring: resistors, transistors, capacitors, inductors, diodes, and much more.
A simpler solution is to copy the existing LCR-T4 tester circuit (it's open source and very simple) with a second Atmega processor. Extend the ZIF socket to 16-pin to give three extra pins into which the unknown component can be plugged. The new Atmega acts as a slave on the SPI bus...
