Analogue Sensors – Calculate the Nonlinearity Introduced by a Load or Pull Down Resistor
Tecwyn Twmffat @ instructables.com discuss about the notlinearity introduced by adding a pull down resistor and why you may get unpredictable readings from your ADC. For many years I found that I would get strange, unpredictable, readings from my sensor related projects at the...

Troubleshooting a 32kHz Crystal Oscillator
How to Actually Make it Oscillate? Now for an oscillator to work, we need an amplifier with a gain of greater than 1, and a phase shift of 360 degrees to get positive feedback. First problem – the transistor was saturated, with Vc stuck near 0V. For an oscillator to start noise...
